WEBVTT 00:00:00.000 --> 00:00:02.560 Okay, let's unpack this. Imagine a patient walks 00:00:02.560 --> 00:00:05.500 into your clinic with knee pain after, say, an 00:00:05.500 --> 00:00:08.699 awkward twist. Or perhaps a footballer limps 00:00:08.699 --> 00:00:11.599 off the pitch after a tackle. Knee injuries are 00:00:11.599 --> 00:00:13.679 incredibly common, aren't they? And amongst them, 00:00:14.300 --> 00:00:15.880 well, meniscal tears stand out as one of the 00:00:15.880 --> 00:00:18.039 most prevalent challenges we face in orthopedics. 00:00:18.320 --> 00:00:21.120 Often quite perplexing, too. So today, we're 00:00:21.120 --> 00:00:23.500 embarking on a deep dive into the world of meniscal 00:00:23.500 --> 00:00:26.320 tears. We're going to peel back the layers right 00:00:26.320 --> 00:00:28.940 from their intricate anatomy to the subtle ways 00:00:28.940 --> 00:00:31.440 they present, how we diagnose them with precision, 00:00:31.460 --> 00:00:34.579 and then the full spectrum of treatment and rehabilitation 00:00:34.579 --> 00:00:37.179 strategies. Things that, you know, truly enhance 00:00:37.179 --> 00:00:39.719 patient outcomes. By the end of this conversation, 00:00:39.719 --> 00:00:42.000 you should have a really systematic, nuanced 00:00:42.000 --> 00:00:44.640 approach to understanding these injuries, hopefully 00:00:44.640 --> 00:00:46.539 equipping you with the knowledge to navigate 00:00:46.539 --> 00:00:49.939 even the complex cases. Joining me today to unravel 00:00:49.939 --> 00:00:52.659 all of this is an absolute authority in orthopedic 00:00:52.659 --> 00:00:54.539 medicine. Welcome. Thank you. It's a pleasure 00:00:54.539 --> 00:00:57.179 to be here. Yes, it's a fundamental yet, as you 00:00:57.179 --> 00:01:00.359 say, undeniably challenging aspect of knee pathology. 00:01:00.439 --> 00:01:02.880 It's a topic that really constantly demands our 00:01:02.880 --> 00:01:06.680 attention and a refined understanding. Absolutely. 00:01:07.299 --> 00:01:10.159 So before we even consider what goes wrong, could 00:01:10.159 --> 00:01:12.459 you walk us through the basics? What exactly 00:01:12.459 --> 00:01:15.079 are these structures we call menisci and what 00:01:15.079 --> 00:01:17.760 vital, almost underestimated roles do they play 00:01:17.760 --> 00:01:20.560 in the knee joint? Well, at its core, the knee 00:01:20.560 --> 00:01:23.640 joint, which is a surprisingly complex hinge 00:01:23.640 --> 00:01:27.640 joint, really, it relies heavily on two crescent 00:01:27.640 --> 00:01:30.359 -shaped fibrocartilaginous structures. These 00:01:30.359 --> 00:01:32.319 are the medial and lateral menicia. You can think 00:01:32.319 --> 00:01:34.420 of them almost like, well, perfectly sculpted 00:01:34.420 --> 00:01:37.599 wedges. Or shock absorbers. They're not just 00:01:37.599 --> 00:01:39.579 passive pads, you see. They're incredibly dynamic 00:01:39.579 --> 00:01:42.780 components. And collectively, they cover a significant 00:01:42.780 --> 00:01:45.680 portion, roughly 70 % of the tibial plateaus' 00:01:45.840 --> 00:01:49.120 articular surface. 70%, wow. Indeed. Their primary 00:01:49.120 --> 00:01:51.640 functions are quite profound. Firstly, they are 00:01:51.640 --> 00:01:53.760 critical low transmitters and shock absorbers 00:01:53.760 --> 00:01:56.420 within that tibiofemoral joint. Just imagine 00:01:56.420 --> 00:01:58.200 the tremendous forces going through your knee 00:01:58.200 --> 00:02:01.269 with every single... step, every jump. The minutiae 00:02:01.269 --> 00:02:03.269 ensure these forces are distributed effectively 00:02:03.269 --> 00:02:05.950 across the joint surfaces. They prevent that 00:02:05.950 --> 00:02:08.449 sort of bone -on -bone grinding and protect the 00:02:08.449 --> 00:02:10.849 delicate articular cartilage. Right. Crucial 00:02:10.849 --> 00:02:13.979 protection. Absolutely. Secondly, their wedge 00:02:13.979 --> 00:02:16.379 shape actually deepens the articular surface 00:02:16.379 --> 00:02:19.139 area. This significantly improves joint congruency, 00:02:19.419 --> 00:02:21.280 making the knee far more stable than it would 00:02:21.280 --> 00:02:23.620 be otherwise. They actually act as a secondary 00:02:23.620 --> 00:02:25.780 stabilizing mechanism within the joint. Okay, 00:02:25.900 --> 00:02:28.000 so stability as well as cushioning. Exactly. 00:02:28.500 --> 00:02:30.639 Now, what's really fascinating from a structural 00:02:30.639 --> 00:02:33.340 point of view is their composition. Around 70 00:02:33.340 --> 00:02:36.219 % of each meniscus is made of Type I collagen, 00:02:36.219 --> 00:02:39.520 and this is arranged primarily in these incredibly 00:02:39.520 --> 00:02:43.189 strong circumferential fibers. That unique arrangement 00:02:43.189 --> 00:02:45.610 is what lends them their remarkable resilience, 00:02:45.770 --> 00:02:48.710 their ability to withstand significant compressive 00:02:48.710 --> 00:02:52.110 and shearing forces without simply collapsing. 00:02:52.229 --> 00:02:54.069 It's a masterpiece of biological engineering, 00:02:54.129 --> 00:02:56.610 really. That structural design, the collagen 00:02:56.610 --> 00:02:58.750 arrangement, it sounds absolutely key to their 00:02:58.750 --> 00:03:01.210 function and their resilience, as you say. And 00:03:01.210 --> 00:03:02.810 I recall there's something quite distinct about 00:03:02.810 --> 00:03:04.849 their blood supply that really impacts how they 00:03:04.849 --> 00:03:06.349 heal, isn't there? It almost sounds like a tale 00:03:06.349 --> 00:03:08.680 of two zones within the meniscus. You've hit 00:03:08.680 --> 00:03:11.259 on a critical point there. The vascularity is 00:03:11.259 --> 00:03:14.180 indeed paramount. It directly influences a tear's 00:03:14.180 --> 00:03:17.199 healing potential. We categorize the minutiae 00:03:17.199 --> 00:03:20.020 into distinct zones based precisely on this blood 00:03:20.020 --> 00:03:23.020 supply. Okay. Think of the peripheral one -third, 00:03:23.479 --> 00:03:25.659 often referred to as the red zone. Think of it 00:03:25.659 --> 00:03:27.960 like a bustling city center with a fantastic 00:03:27.960 --> 00:03:30.340 road network for blood vessels. Right. This area 00:03:30.340 --> 00:03:33.280 is well vascularized, primarily supplied by branches 00:03:33.280 --> 00:03:35.240 of the medial and lateral genicular arteries. 00:03:35.939 --> 00:03:40.840 So tears within this zone, they have the highest 00:03:40.840 --> 00:03:44.400 potential for spontaneous healing or indeed successful 00:03:44.400 --> 00:03:46.240 surgical repair. Peace, the blood's getting there. 00:03:46.659 --> 00:03:49.120 Precisely because there's ample blood flow necessary 00:03:49.120 --> 00:03:51.900 for tissue regeneration, bringing all those healing 00:03:51.900 --> 00:03:54.199 factors to the site. It's like having a dedicated 00:03:54.199 --> 00:03:56.240 repair crew with all their tools readily available. 00:03:57.020 --> 00:03:59.180 Conversely, the inner two -thirds of the adult 00:03:59.180 --> 00:04:01.879 menisci is largely vascular. This is what we 00:04:01.879 --> 00:04:04.539 call the white zone. It receives nutrition predominantly 00:04:04.539 --> 00:04:07.300 through diffusion from the synovial fluid, which 00:04:07.300 --> 00:04:10.000 is far less efficient. Right. Much slower. Much 00:04:10.000 --> 00:04:13.099 slower. Much less efficient. So healing in this 00:04:13.099 --> 00:04:16.139 area is consequently far more challenging. It's 00:04:16.139 --> 00:04:18.259 like a remote village where getting supplies 00:04:18.259 --> 00:04:20.480 is a real struggle. Then there's also the red 00:04:20.480 --> 00:04:22.579 -white zone, which lies in between possessing 00:04:22.579 --> 00:04:24.980 a more limited blood supply, sort of suburban 00:04:24.980 --> 00:04:27.899 area, if you like. OK. This anatomical distinction 00:04:27.899 --> 00:04:30.639 is fundamental. It's truly the bedrock of our 00:04:30.639 --> 00:04:33.839 treatment decisions. A tear in the red zone might 00:04:33.839 --> 00:04:36.139 respond well to conservative management or repair, 00:04:36.720 --> 00:04:39.279 whereas a tear deep in the white zone often requires 00:04:39.279 --> 00:04:42.279 a different approach, usually excisional, removing 00:04:42.279 --> 00:04:44.579 the torn part. That makes sense. It guides the 00:04:44.579 --> 00:04:47.389 whole strategy. Absolutely. And beyond vascularity, 00:04:47.550 --> 00:04:49.790 something often overlooked, the meniche also 00:04:49.790 --> 00:04:52.790 play a proprioceptive role. Ah, interesting. 00:04:53.029 --> 00:04:55.750 The sensory aspect. Yes. The peripheral two -thirds 00:04:55.750 --> 00:04:58.110 contain non -susceptive free nerve endings pain 00:04:58.110 --> 00:05:00.889 receptors. Whilst mechanoreceptors are specifically 00:05:00.889 --> 00:05:03.069 located in the anterior and posterior horns, 00:05:03.810 --> 00:05:06.329 this sensory input contributes to our awareness 00:05:06.329 --> 00:05:08.769 of knee position and movement. It essentially 00:05:08.769 --> 00:05:11.910 tells our brain where our knee is in space. Approprioception. 00:05:12.269 --> 00:05:14.810 Exactly. So damage here can affect not just stability, 00:05:15.009 --> 00:05:17.990 but also balance and coordination. It's remarkable 00:05:17.990 --> 00:05:20.970 how such a small structure can have such a profound 00:05:20.970 --> 00:05:24.310 impact. Mechanical cushioning, stability, sensory 00:05:24.310 --> 00:05:28.300 roles. fascinating, particularly that proprioceptive 00:05:28.300 --> 00:05:31.040 aspect. Now, is there a difference in how the 00:05:31.040 --> 00:05:34.399 medial and lateral menisci are actually attached? 00:05:34.819 --> 00:05:37.459 Does that influence their susceptibility to injury? 00:05:37.839 --> 00:05:40.180 Because it seems one gets injured more often 00:05:40.180 --> 00:05:43.120 than the other. Yes, absolutely. There's a notable 00:05:43.120 --> 00:05:45.680 anatomical difference that directly impacts their 00:05:45.680 --> 00:05:47.920 vulnerability, and it's something we see reflected 00:05:47.920 --> 00:05:50.740 in the epidemiological data constantly. The medial 00:05:50.740 --> 00:05:52.839 meniscus has a much firmer attachment to the 00:05:52.839 --> 00:05:56.100 joint capsule and also to the fibers of the medial 00:05:56.100 --> 00:05:58.759 collateral ligament the MCL okay this makes it 00:05:58.759 --> 00:06:01.319 considerably less mobile that's quite tethered 00:06:01.319 --> 00:06:03.199 down you could say right compare that to the 00:06:03.199 --> 00:06:05.540 lateral meniscus it has looser attachments with 00:06:05.540 --> 00:06:08.199 the joint capsule and crucially it does not connect 00:06:08.199 --> 00:06:10.220 with the lateral collateral ligament the LCL 00:06:10.220 --> 00:06:15.019 ah okay more freedom to move precisely it has 00:06:15.019 --> 00:06:18.170 far greater mobility Now, this reduced mobility 00:06:18.170 --> 00:06:21.370 of the medial meniscus is a key factor in why 00:06:21.370 --> 00:06:23.889 medial meniscal tears are statistically more 00:06:23.889 --> 00:06:26.329 common than lateral tears in general clinical 00:06:26.329 --> 00:06:28.649 practice. I see. It just can't get out of the 00:06:28.649 --> 00:06:31.410 way as easily. That's a good way to put it. It's 00:06:31.410 --> 00:06:34.290 simply less able to move out of the way of potentially 00:06:34.290 --> 00:06:37.370 damaging rotational or shearing forces. This 00:06:37.370 --> 00:06:39.750 directly influences the epidemiological data 00:06:39.750 --> 00:06:42.610 we see, with medial meniscal tears being more 00:06:42.610 --> 00:06:45.050 prevalent, a point sometimes missed in a quick 00:06:45.050 --> 00:06:47.160 review of knee anatomy. So if we connect this 00:06:47.160 --> 00:06:49.339 to the bigger picture, when you're assessing 00:06:49.339 --> 00:06:52.199 a patient with a suspected meniscal tear, your 00:06:52.199 --> 00:06:54.199 index of suspicion should generally be a bit 00:06:54.199 --> 00:06:56.339 higher for the medial side. Generally speaking, 00:06:56.560 --> 00:06:59.160 yes. Although, as we'll discuss, certain injury 00:06:59.160 --> 00:07:01.800 patterns might point more laterally. But overall, 00:07:02.040 --> 00:07:04.120 medial is more common. Right. Good practical 00:07:04.120 --> 00:07:06.100 point. So understanding how they're meticulously 00:07:06.100 --> 00:07:08.480 built, let's now talk about how these amazing 00:07:08.480 --> 00:07:10.600 structures actually break. What are the common 00:07:10.600 --> 00:07:12.980 mechanisms and the key risk factors that lead 00:07:12.980 --> 00:07:15.990 to meniscal tears? Well, Meniscal tears broadly 00:07:15.990 --> 00:07:18.490 fall into two distinct categories, though sometimes 00:07:18.490 --> 00:07:21.149 they can overlap a bit. These are acute traumatic 00:07:21.149 --> 00:07:24.449 tears and degenerative tears, and their mechanisms 00:07:24.449 --> 00:07:27.509 are quite different. Okay. Acute first. Right. 00:07:27.670 --> 00:07:30.350 Acute tears typically occur due to sudden rucational 00:07:30.350 --> 00:07:33.269 or shearing forces placed across the tabiofemoral 00:07:33.269 --> 00:07:36.250 joint, especially when there's an increased axial 00:07:36.250 --> 00:07:39.329 load. Think about scenarios involving what we 00:07:39.329 --> 00:07:41.750 call increased degrees of closed kinetic chain 00:07:41.750 --> 00:07:43.970 flexion. That's essentially when your foot is 00:07:43.970 --> 00:07:45.949 fixed on the ground. Like squatting or twisting. 00:07:46.370 --> 00:07:48.529 Exactly. Kneeling, squatting, lifting heavy weights. 00:07:49.370 --> 00:07:51.589 These tiers are also incredibly common in sports 00:07:51.589 --> 00:07:54.310 that demand rapid acceleration, deceleration, 00:07:54.589 --> 00:07:56.750 and quick changes of direction. Think football, 00:07:57.310 --> 00:08:02.050 rugby, skiing, activities with pivoting. A direct 00:08:02.050 --> 00:08:04.129 traumatic impact to the knee, like a fall or 00:08:04.129 --> 00:08:06.949 a collision, can also cause these tears. They 00:08:06.949 --> 00:08:09.050 often present as vertical longitudinal tears, 00:08:09.370 --> 00:08:11.769 and we typically see a peak incidence in individuals 00:08:11.769 --> 00:08:15.410 aged, say, 21 to 30 years, often athletes, due 00:08:15.410 --> 00:08:17.430 to sports -related incidents. Okay, the younger, 00:08:17.589 --> 00:08:20.050 more active group typically. And degenerative. 00:08:20.430 --> 00:08:22.750 Degenerative tears, on the other hand, are more 00:08:22.750 --> 00:08:25.290 common in adults over the age of 40, and they 00:08:25.290 --> 00:08:28.279 can occur with relatively less force. often without 00:08:28.279 --> 00:08:31.459 a distinct inciting event at all. So not necessarily 00:08:31.459 --> 00:08:34.899 a big injury. Not at all. For instance, an awkward 00:08:34.899 --> 00:08:37.299 twist when simply getting up from a chair or 00:08:37.299 --> 00:08:39.820 even just turning over in bed might be enough 00:08:39.820 --> 00:08:42.220 to cause a tear in an aging, perhaps slightly 00:08:42.220 --> 00:08:45.179 worn meniscus. These are frequently associated 00:08:45.179 --> 00:08:47.620 with pre -existing osteoarthritis, where the 00:08:47.620 --> 00:08:50.320 tissue simply becomes worn over time due to age 00:08:50.320 --> 00:08:52.679 -related changes and cumulative stress. Wear 00:08:52.679 --> 00:08:55.799 and tear. Essentially, yes. They are more prevalent 00:08:55.799 --> 00:08:58.360 in older populations, making up about 30 % of 00:08:58.360 --> 00:09:00.919 all meniscus tears. Peak incidence occurs in 00:09:00.919 --> 00:09:04.899 men aged 41 to 50 and women aged 61 to 70. That 00:09:04.899 --> 00:09:07.039 distinction between acute, often high -energy, 00:09:07.039 --> 00:09:09.460 trauma and the more insidious nature of degenerative 00:09:09.460 --> 00:09:12.279 tears is vital for our diagnostic approach, isn't 00:09:12.279 --> 00:09:14.500 it? Absolutely. It shapes how you take the history 00:09:14.500 --> 00:09:17.070 and what you look for. Given these mechanisms, 00:09:17.190 --> 00:09:20.350 who is most susceptible? Are there specific demographics, 00:09:20.389 --> 00:09:22.690 activities, or even pre -existing conditions 00:09:22.690 --> 00:09:25.889 that put individuals at higher risk? Yes, definitely. 00:09:26.590 --> 00:09:28.309 Epidemiological studies, for example, from the 00:09:28.309 --> 00:09:30.970 U .S. indicate a general incidence rate of around 00:09:30.970 --> 00:09:35.269 61 meniscal tears per 100 ,000 people. However, 00:09:35.269 --> 00:09:38.470 that figure jumps significantly, up to 8 .7 per 00:09:38.470 --> 00:09:41.870 1 ,000 in active duty military populations. Wow, 00:09:41.990 --> 00:09:45.190 quite a leap. It is, and that immediate jump 00:09:45.340 --> 00:09:48.360 tells you there's a very strong link to demanding 00:09:48.360 --> 00:09:50.399 physical activities and repetitive stress. Makes 00:09:50.399 --> 00:09:53.179 sense. Occupations requiring frequent squatting 00:09:53.179 --> 00:09:55.860 or kneeling. Think plumbers, carpet fitters, 00:09:56.200 --> 00:09:58.399 construction workers, and sports with pivoting 00:09:58.399 --> 00:10:01.639 and cutting movements. So soccer, rugby, football, 00:10:01.980 --> 00:10:04.779 basketball, skiing, wrestling. They all notably 00:10:04.779 --> 00:10:07.720 increase the risk. We also see a higher incidence 00:10:07.720 --> 00:10:10.620 in males compared to females and in individuals 00:10:10.620 --> 00:10:13.740 over 40 years of age, largely due to those degenerative 00:10:13.740 --> 00:10:16.240 changes starting. Right. Interestingly, and as 00:10:16.240 --> 00:10:18.580 we touched upon earlier, medial meniscal tears 00:10:18.580 --> 00:10:20.500 are generally more common than lateral ones in 00:10:20.500 --> 00:10:22.860 the general population, primarily due to that 00:10:22.860 --> 00:10:24.759 decreased mobility from its firm connection to 00:10:24.759 --> 00:10:27.379 the MCL. However, it's worth noting a key exception. 00:10:27.659 --> 00:10:30.399 In the setting of an acute ACL tear, lateral 00:10:30.399 --> 00:10:33.259 meniscal tears can actually be more common initially, 00:10:33.559 --> 00:10:36.120 right at the time of injury. Ah, okay, so the 00:10:36.120 --> 00:10:39.000 pattern shifts with an ACL injury. It can do. 00:10:39.129 --> 00:10:41.230 And this leads us to a really important clinical 00:10:41.230 --> 00:10:44.690 point. For those with anterior cruciate ligament 00:10:44.690 --> 00:10:48.830 or ACL deficient knees. So an ACL tear that hasn't 00:10:48.830 --> 00:10:51.909 been reconstructed, there's a heightened risk 00:10:51.909 --> 00:10:54.330 of developing secondary medial meniscal tears 00:10:54.330 --> 00:10:56.870 over time. Right. The chronic instability takes 00:10:56.870 --> 00:10:59.919 its toll. Precisely. Particularly if that ACL 00:10:59.919 --> 00:11:02.200 reconstruction is delayed for over a year from 00:11:02.200 --> 00:11:04.919 the initial injury, it's almost as if the knee's 00:11:04.919 --> 00:11:07.980 instability puts extra stress on the medial meniscus. 00:11:08.080 --> 00:11:10.980 That's a really key point for managing ACL injuries. 00:11:11.200 --> 00:11:13.500 It is. Delay can have consequences beyond the 00:11:13.500 --> 00:11:15.559 ligament itself. And what about younger patients? 00:11:15.700 --> 00:11:18.139 You mentioned tears are rare under 10. Generally, 00:11:18.360 --> 00:11:20.639 yes, but there's an important exception. The 00:11:20.639 --> 00:11:23.519 presence of a discoid meniscus. Ah, the anatomical 00:11:23.519 --> 00:11:26.220 variant. Exactly. Most often occurring in the 00:11:26.220 --> 00:11:29.139 lateral meniscus, where it has an abnormal, usually 00:11:29.139 --> 00:11:31.620 more disc -like shape instead of the normal crescent. 00:11:31.820 --> 00:11:34.779 This can predispose younger individuals to tears 00:11:34.779 --> 00:11:38.200 at an earlier age because of its inherent instability 00:11:38.200 --> 00:11:41.460 and abnormal biomechanics. Doesn't function quite 00:11:41.460 --> 00:11:44.320 right. So if you see a young child presenting 00:11:44.320 --> 00:11:47.299 with what looks like meniscal symptoms, you absolutely 00:11:47.299 --> 00:11:49.720 have to consider the possibility of discoid meniscus. 00:11:50.100 --> 00:11:53.720 It needs specific management. Right. Okay, so 00:11:53.720 --> 00:11:56.259 once a tear occurs, And this is where it gets 00:11:56.259 --> 00:11:58.039 really interesting for diagnostics and treatment 00:11:58.039 --> 00:12:00.960 planning. How exactly do we classify them? I 00:12:00.960 --> 00:12:03.000 understand the morphology, the shape, and the 00:12:03.000 --> 00:12:05.600 location, especially relative to those vascular 00:12:05.600 --> 00:12:08.759 zones, are incredibly important. What's the key 00:12:08.759 --> 00:12:11.500 takeaway for us here? Precisely. This is arguably 00:12:11.500 --> 00:12:13.620 the most critical piece of the puzzle for making 00:12:13.620 --> 00:12:16.240 treatment decisions. Meniscal tiers are categorized 00:12:16.240 --> 00:12:18.779 by both their shape, their morphology, and their 00:12:18.779 --> 00:12:21.450 location. And we primarily visualize this on 00:12:21.450 --> 00:12:24.289 MRI scans. The key insight here for you in practice 00:12:24.289 --> 00:12:27.350 is that the vascular zone dictates destiny. Right. 00:12:27.610 --> 00:12:30.230 That's the crucial link. It is. A tear in the 00:12:30.230 --> 00:12:32.870 red zone is fundamentally a different beast than 00:12:32.870 --> 00:12:35.029 one in the white zone when it comes to healing 00:12:35.029 --> 00:12:37.110 potential and what you can realistically offer 00:12:37.110 --> 00:12:39.669 your patient. This isn't just academic. It's 00:12:39.669 --> 00:12:41.490 the bedrock of your treatment decision making. 00:12:42.230 --> 00:12:44.700 On MRI. the presence of a high -end -tensity 00:12:44.700 --> 00:12:47.360 intraminiscal signal. A bright line. Essentially, 00:12:47.679 --> 00:12:50.220 yes. A bright line on certain sequences communicating 00:12:50.220 --> 00:12:52.460 with at least one articular surface on the otherwise 00:12:52.460 --> 00:12:55.259 black -appearing meniscal tissue that's usually 00:12:55.259 --> 00:12:57.879 indicative of a tear. Okay, so what are the common 00:12:57.879 --> 00:13:00.179 patterns we see? Right, let's briefly go through 00:13:00.179 --> 00:13:03.080 the common patterns. Each has distinct characteristics 00:13:03.080 --> 00:13:05.639 and, importantly, implications for treatment. 00:13:05.980 --> 00:13:08.740 First, we have horizontal or cleavage tears. 00:13:09.419 --> 00:13:12.120 These run parallel to the tibial plateau. They 00:13:12.120 --> 00:13:14.720 effectively split the meniscus into a superior 00:13:14.720 --> 00:13:17.039 and an inferior layer. Okay, splitting it flat. 00:13:17.519 --> 00:13:19.720 Exactly. They're more likely to occur in people 00:13:19.720 --> 00:13:22.899 over 40, often without a distinct traumatic event. 00:13:23.600 --> 00:13:26.620 They're often degenerative in nature. Healing 00:13:26.620 --> 00:13:28.320 potential for these is generally low because 00:13:28.320 --> 00:13:30.539 they commonly originate in that vascular inner 00:13:30.539 --> 00:13:32.980 zone and are exposed to constant shear stress 00:13:32.980 --> 00:13:35.389 during weight -bearing. Right. Bad location, 00:13:35.549 --> 00:13:38.850 bad forces. Pretty much, although there's a fascinating 00:13:38.850 --> 00:13:42.289 nuance. Some central horizontal tears might experience 00:13:42.289 --> 00:13:44.769 better healing if they are subjected to more 00:13:44.769 --> 00:13:48.289 compressive rather than sheer stress. Some studies 00:13:48.289 --> 00:13:50.789 report good healing with specific rehab protocols, 00:13:51.629 --> 00:13:54.350 but generally they're tough to heal. Okay, what's 00:13:54.350 --> 00:13:58.090 next? Next, longitudinal or vertical tears. These 00:13:58.090 --> 00:14:00.950 run perpendicular to the tibial plateau, but 00:14:00.950 --> 00:14:04.039 parallel to the meniscus's long axis. Think along 00:14:04.039 --> 00:14:06.759 the curve. These can occur in areas with better 00:14:06.759 --> 00:14:09.159 blood supply, often making them more amenable 00:14:09.159 --> 00:14:12.200 to repair, offering a greater potential for healing, 00:14:12.779 --> 00:14:14.240 especially if they're in that peripheral red 00:14:14.240 --> 00:14:16.600 zone. So potentially repairable. Potentially, 00:14:16.659 --> 00:14:19.519 yes. Then we have radial tears. These extend 00:14:19.519 --> 00:14:21.679 perpendicular to both the tibial plateau and 00:14:21.679 --> 00:14:24.059 the long axis of the meniscus. They typically 00:14:24.059 --> 00:14:26.139 start from the inner free edge and go outwards. 00:14:26.159 --> 00:14:28.840 Like a slice through it. Exactly. They are quite 00:14:28.840 --> 00:14:32.330 problematic biomechanically. A complete radial 00:14:32.330 --> 00:14:34.470 tear that extends all the way out to the menisco 00:14:34.470 --> 00:14:38.529 -capsular junction is, in functional terms, pretty 00:14:38.529 --> 00:14:42.289 much equivalent to a posterior root tear. It 00:14:42.289 --> 00:14:45.070 significantly disrupts the crucial hoop stress 00:14:45.070 --> 00:14:47.649 mechanism of the meniscus. It stops it working 00:14:47.649 --> 00:14:50.049 like a C -shaped ring. Right. It compromises 00:14:50.049 --> 00:14:51.950 the whole structure. It does. It effectively 00:14:51.950 --> 00:14:54.909 allows the meniscus to flop or extrude outwards, 00:14:55.269 --> 00:14:57.960 losing its shock absorption function. These often 00:14:57.960 --> 00:15:00.220 require surgical intervention to restore that 00:15:00.220 --> 00:15:02.899 hope tension. Okay. Very different implications. 00:15:03.100 --> 00:15:05.559 Very different. Then we have complex tears. These 00:15:05.559 --> 00:15:08.559 just involve a combination of patterns, horizontal, 00:15:08.620 --> 00:15:11.080 longitudinal, radial elements, all mixed together. 00:15:11.259 --> 00:15:13.639 Messy one. You could say that. They are frequently 00:15:13.639 --> 00:15:16.220 seen with degenerative joint changes and typically 00:15:16.220 --> 00:15:19.080 not amenable to repair. They often lead to further 00:15:19.080 --> 00:15:21.899 joint degeneration and usually require a partial 00:15:21.899 --> 00:15:24.279 meniscectomy. Right. Just cleaning up the damaged 00:15:24.279 --> 00:15:27.539 bits. Exactly. Then there are displaced tiers. 00:15:28.139 --> 00:15:31.360 This involves either complete detachment or flipping 00:15:31.360 --> 00:15:34.620 of a piece of the meniscus into the joint. A 00:15:34.620 --> 00:15:37.080 specific and clinically very significant type 00:15:37.080 --> 00:15:40.059 is the bucket handle tear. Ah yes, the classic 00:15:40.059 --> 00:15:42.740 locking tear. Precisely. It's a large fragment, 00:15:42.820 --> 00:15:45.279 usually from a complete longitudinal tear, that 00:15:45.279 --> 00:15:47.639 has actually migrated centrally, flipping over 00:15:47.639 --> 00:15:49.659 into the middle of the joint, over the remaining 00:15:49.659 --> 00:15:52.740 meniscus. These often cause severe mechanical 00:15:52.740 --> 00:15:55.200 locking symptoms, making it impossible for the 00:15:55.200 --> 00:15:57.759 patient to fully extend their knee. Interestingly, 00:15:58.399 --> 00:16:00.399 recent evidence suggests that for the newer generation, 00:16:00.899 --> 00:16:03.200 all inside repair devices, the re -operation 00:16:03.200 --> 00:16:05.639 rates and clinical outcomes are actually becoming 00:16:05.639 --> 00:16:07.980 comparable for radial tears and bucket handle 00:16:07.980 --> 00:16:10.289 tears. which is quite a promising development. 00:16:10.429 --> 00:16:12.409 That is interesting, better repair options. Yes. 00:16:12.850 --> 00:16:14.870 We also classify flap tears, which are partially 00:16:14.870 --> 00:16:17.429 detached fragments, often from horizontal tears 00:16:17.429 --> 00:16:21.269 and ramp lesions. These are specific menisco 00:16:21.269 --> 00:16:23.950 -capsular separations found in the posterior 00:16:23.950 --> 00:16:27.470 inner part of the medial meniscus, usually, often 00:16:27.470 --> 00:16:30.730 in that well -vascularized red zone. They're 00:16:30.730 --> 00:16:33.940 frequently associated with ACL tears. Smaller 00:16:33.940 --> 00:16:36.720 ramp lesions may actually heal non -surgically, 00:16:37.000 --> 00:16:38.759 again, underscoring that critical importance 00:16:38.759 --> 00:16:41.559 of tear location and blood supply. Right. Location, 00:16:41.559 --> 00:16:44.299 location, location. It really is key. Finally, 00:16:44.440 --> 00:16:46.799 root tears. These involve the detachment of the 00:16:46.799 --> 00:16:49.759 meniscus right at its posterior attachment, its 00:16:49.759 --> 00:16:53.720 root, onto the tibia, medial or lateral. Okay. 00:16:53.879 --> 00:16:56.860 Where it anchors down. Exactly. While less common, 00:16:56.980 --> 00:16:59.100 especially on the medial side, these can have 00:16:59.100 --> 00:17:01.059 incredibly significant implications for knee 00:17:01.059 --> 00:17:04.140 function. They often lead to rapid meniscal extrusion 00:17:04.140 --> 00:17:06.559 where the meniscus squishes out from between 00:17:06.559 --> 00:17:08.599 the bones and very rapid joint degeneration. 00:17:09.299 --> 00:17:11.440 It essentially transforms a healthy knee into 00:17:11.440 --> 00:17:14.759 an arthritic one alarmingly quickly. So quite 00:17:14.759 --> 00:17:17.519 catastrophic biomechanically. They can be. Surgical 00:17:17.519 --> 00:17:19.079 repairs generally consider the most effective 00:17:19.079 --> 00:17:21.480 approach for these root tears to try and restore 00:17:21.480 --> 00:17:24.000 proper knee biomechanics and prevent that almost 00:17:24.000 --> 00:17:27.089 inevitable cascade to arthritis. Right. A lot 00:17:27.089 --> 00:17:29.650 to consider in the classification. So the specific 00:17:29.650 --> 00:17:33.130 pattern and, crucially, that vascular zone really 00:17:33.130 --> 00:17:35.250 dictate the likelihood of success for different 00:17:35.250 --> 00:17:37.829 treatments. That's a critical distinction for 00:17:37.829 --> 00:17:40.630 us to consider in clinical practice. Helps guide 00:17:40.630 --> 00:17:42.730 those patient conversations about prognosis and 00:17:42.730 --> 00:17:45.529 options. Now, let's turn to how these injuries 00:17:45.529 --> 00:17:48.150 typically present to us clinically. What are 00:17:48.150 --> 00:17:50.509 the hallmark symptoms a patient might describe? 00:17:50.789 --> 00:17:53.150 And what's the diagnostic pathway we should follow 00:17:53.150 --> 00:17:55.400 once they walk into our clinic? Well, the clinical 00:17:55.400 --> 00:17:58.119 presentation is highly variable. It depends heavily 00:17:58.119 --> 00:18:00.759 on the injury mechanism, the type of tear, and 00:18:00.759 --> 00:18:03.759 any concomitant damage like an ACL tear. It's 00:18:03.759 --> 00:18:06.759 rarely a completely textbook case. Patients might 00:18:06.759 --> 00:18:09.759 report a distinct sensation of a pop with immediate 00:18:09.759 --> 00:18:12.460 knee effusion or swelling during a high -impact 00:18:12.460 --> 00:18:15.230 activity or acute trauma. This scenario is often 00:18:15.230 --> 00:18:18.410 associated with an ACL tear and a possible medial 00:18:18.410 --> 00:18:20.950 meniscal tear as these injuries frequently occur 00:18:20.950 --> 00:18:24.009 together. The classic unhappy triad if the MCL 00:18:24.009 --> 00:18:25.589 is also involved. Right, the combined injury 00:18:25.589 --> 00:18:28.890 pattern. Exactly. In contrast, a fusion that 00:18:28.890 --> 00:18:31.990 develops more gradually, perhaps over 24 hours, 00:18:32.470 --> 00:18:35.269 is often more indicative of an isolated meniscal 00:18:35.269 --> 00:18:37.809 tear without significant ligamentous damage. 00:18:37.970 --> 00:18:41.220 Okay. more subtle onset of swelling. Yes, and 00:18:41.220 --> 00:18:43.339 symptoms can also be quite insidious, particularly 00:18:43.339 --> 00:18:45.680 with those degenerative tears. You might just 00:18:45.680 --> 00:18:48.059 see low -grade effusion and stiffness developing 00:18:48.059 --> 00:18:50.599 over several days or weeks without a distinct 00:18:50.599 --> 00:18:53.920 inciting event. Perhaps just after a prolonged 00:18:53.920 --> 00:18:56.740 period of activity, or even sometimes after rest, 00:18:57.380 --> 00:18:59.259 pain is typically localized over the anterior 00:18:59.259 --> 00:19:01.900 medial or anterior lateral joint line. Although 00:19:01.900 --> 00:19:04.140 it can also be reported more medially, laterally, 00:19:04.180 --> 00:19:06.640 or even posteriorly, depending on the tear's 00:19:06.640 --> 00:19:09.140 exact location. But the joint line is the key 00:19:09.140 --> 00:19:12.000 area. It's a very common finding. But crucially, 00:19:12.220 --> 00:19:14.119 patients may also describe mechanical symptoms. 00:19:14.160 --> 00:19:16.500 And these are really our red flags for something 00:19:16.500 --> 00:19:20.680 catching or blocking. Locking. Exactly. Locking, 00:19:21.019 --> 00:19:23.140 where the knee gets truly stuck and can't be 00:19:23.140 --> 00:19:25.779 straightened. Clicking, which is often a reproducible 00:19:25.779 --> 00:19:29.309 sound or sensation. Or catching. where it feels 00:19:29.309 --> 00:19:31.549 like something is physically getting caught inside 00:19:31.549 --> 00:19:35.049 the joint. These all occur when torn pieces of 00:19:35.049 --> 00:19:37.269 the meniscus interfere with the smooth movement 00:19:37.269 --> 00:19:40.809 of the knee. They might also report an intermittent 00:19:40.809 --> 00:19:43.710 inability to fully extend the knee, what we call 00:19:43.710 --> 00:19:46.549 a fixed flexion deformity, or a feeling of the 00:19:46.549 --> 00:19:48.930 knee giving way, suggesting some instability. 00:19:49.829 --> 00:19:53.190 Sometimes, especially acutely, patients experience 00:19:53.190 --> 00:19:55.470 that popping sensation at the time of injury, 00:19:55.930 --> 00:19:58.170 followed perhaps by creaking sounds during movement. 00:19:58.269 --> 00:20:00.789 And in acute cases, the knee may feel warm to 00:20:00.789 --> 00:20:04.230 the touch due to the inflammation. So a thorough 00:20:04.230 --> 00:20:06.789 history really eliciting those mechanical symptoms 00:20:06.789 --> 00:20:09.910 is absolutely paramount. Paramount, yes. Distinguishing 00:20:09.910 --> 00:20:12.250 true locking from just stiffness is key. And 00:20:12.250 --> 00:20:14.109 what about the physical examination? What objective 00:20:14.109 --> 00:20:16.490 signs are we looking for? And which special tests 00:20:16.490 --> 00:20:18.890 offer the most diagnostic value, especially thinking 00:20:18.890 --> 00:20:22.430 about sensitivity and specificity? Right. A comprehensive 00:20:22.430 --> 00:20:24.970 physical examination should include careful inspection 00:20:24.970 --> 00:20:27.890 of the knee for any visible edema or swelling. 00:20:28.119 --> 00:20:31.880 any obvious deformity. Then palpation, particularly 00:20:31.880 --> 00:20:34.200 of the joint line. Assessment of standing and 00:20:34.200 --> 00:20:36.279 supine range of motion looking for any loss of 00:20:36.279 --> 00:20:38.660 extension or flexion and muscle strength testing, 00:20:39.099 --> 00:20:41.980 though weakness is often secondary to pain. We 00:20:41.980 --> 00:20:44.839 also perform specific provocative tests. Okay. 00:20:45.019 --> 00:20:47.660 Joint line tenderness first. Yes. Antromedial 00:20:47.660 --> 00:20:50.119 and antrilateral joint line tenderness performed 00:20:50.119 --> 00:20:52.299 with the patient's knee flexed to 90 degrees, 00:20:52.539 --> 00:20:54.859 perhaps dangling off the edge of the couch. This 00:20:54.859 --> 00:20:58.079 is a highly sensitive and specific finding. Reported 00:20:58.079 --> 00:21:00.960 accuracy is around 83 % for both medial and lateral 00:21:00.960 --> 00:21:03.759 tears. If you can really pinpoint the pain exactly 00:21:03.759 --> 00:21:05.640 to that joint line, it's a strong indicator. 00:21:05.940 --> 00:21:09.099 Right. Very useful clinically. Very. Pain and 00:21:09.099 --> 00:21:11.259 deficits in either flexion or extension range 00:21:11.259 --> 00:21:13.579 of motion may also be present, depending on the 00:21:13.579 --> 00:21:16.279 tear type and the amount of effusion. A bucket 00:21:16.279 --> 00:21:18.599 handle tear, for instance, will classically severely 00:21:18.599 --> 00:21:21.759 limit extension. Whilst deficits in open kinetic 00:21:21.759 --> 00:21:23.759 chain knee strength testing are unlikely to be 00:21:23.759 --> 00:21:26.180 the primary finding, you might see an italgic 00:21:26.180 --> 00:21:29.180 gait, a limp, to avoid pain or increased pain 00:21:29.180 --> 00:21:32.259 with single or double leg squatting due to those 00:21:32.259 --> 00:21:34.220 increased compressive forces over the menisci. 00:21:35.049 --> 00:21:37.890 And the provocative tests. Which ones are most 00:21:37.890 --> 00:21:40.069 reliable? Well, the Thessaly test actually stands 00:21:40.069 --> 00:21:42.730 out with quite impressive metrics. Around 75 00:21:42.730 --> 00:21:46.329 % sensitivity and 87 % specificity in some studies. 00:21:46.430 --> 00:21:48.509 How is that performed again? The patient stands 00:21:48.509 --> 00:21:51.170 on one leg with the knee flexed slightly, say 00:21:51.170 --> 00:21:54.490 20 degrees. They then internally and externally 00:21:54.490 --> 00:21:56.690 rotate their body on the fixed foot and knee, 00:21:57.170 --> 00:22:00.039 maybe performing a slight squat as well. If this 00:22:00.039 --> 00:22:02.299 twisting motion under load elicits discomfort, 00:22:02.519 --> 00:22:04.640 clicking, or a sense of instability or locking, 00:22:05.059 --> 00:22:07.480 it's considered a positive test. It's essentially 00:22:07.480 --> 00:22:10.380 trying to trap or pinch the torn meniscus between 00:22:10.380 --> 00:22:13.000 the femur and tibia. Right. Simulates the injury 00:22:13.000 --> 00:22:15.740 mechanism. To some extent, yes. The McMurray's 00:22:15.740 --> 00:22:18.259 test, though perhaps more widely known and commonly 00:22:18.259 --> 00:22:20.799 taught, actually has slightly lower metrics in 00:22:20.799 --> 00:22:23.599 some reviews, maybe around 61 % sensitivity and 00:22:23.599 --> 00:22:26.599 84 % specificity. Still useful, though. Still 00:22:26.599 --> 00:22:29.730 part of the standard exam, yes. It involves passively 00:22:29.730 --> 00:22:32.650 extending the supine patient's knee from a fully 00:22:32.650 --> 00:22:35.490 flexed position up towards 90 degrees whilst 00:22:35.490 --> 00:22:38.049 maintaining full external or internal rotation 00:22:38.049 --> 00:22:41.650 of the tibia. A palpable popper click combined 00:22:41.650 --> 00:22:44.410 with pain reproduction along the joint line indicates 00:22:44.410 --> 00:22:48.130 a positive test. Traditionally, external rotation 00:22:48.130 --> 00:22:51.190 stresses the medial meniscus and internal rotation 00:22:51.190 --> 00:22:54.049 stresses the lateral. Apley's compression test. 00:22:54.200 --> 00:22:56.700 where the prone patient's knee is passively flexed 00:22:56.700 --> 00:22:59.579 to 90 degrees and then rotated externally or 00:22:59.579 --> 00:23:01.920 internally with an axial compressive force down 00:23:01.920 --> 00:23:04.220 through the heel. This actually has quite low 00:23:04.220 --> 00:23:06.460 sensitivity, maybe less than 20%. Oh, really? 00:23:06.660 --> 00:23:08.880 Yes, but its specificity can be quite high, maybe 00:23:08.880 --> 00:23:11.839 up to 80, 90%. So Walston might miss a lot of 00:23:11.839 --> 00:23:14.740 tears. If it is positive, it's quite indicative 00:23:14.740 --> 00:23:17.220 of a meniscal problem rather than ligamentous. 00:23:17.359 --> 00:23:19.740 Right. So useful like positive, but a negative 00:23:19.740 --> 00:23:22.299 doesn't rule much out. Exactly. It's more about 00:23:22.299 --> 00:23:24.839 the combination of findings history, joint line 00:23:24.839 --> 00:23:27.599 tenderness, range of motion, and these tests 00:23:27.599 --> 00:23:30.150 that builds the clinical picture. Given that 00:23:30.150 --> 00:23:32.390 variability in presentation and physical exam 00:23:32.390 --> 00:23:35.369 findings, which can sometimes be subtle, what 00:23:35.369 --> 00:23:38.049 imaging studies are absolutely essential to confirm 00:23:38.049 --> 00:23:40.390 the diagnosis and really characterize the tear 00:23:40.390 --> 00:23:43.309 moving beyond just clinical suspicion? Right. 00:23:43.710 --> 00:23:45.829 When a meniscal tear is suspected clinically, 00:23:45.910 --> 00:23:48.670 we always begin with standard radiographs, x 00:23:48.670 --> 00:23:51.890 -rays. Standard views. Yes, including AP, enter 00:23:51.890 --> 00:23:55.329 posterior, lateral oblique views, often a sunrise 00:23:55.329 --> 00:23:58.089 or skyline view for the patella femoral joint, 00:23:58.390 --> 00:24:00.819 and crucial weight -bearing views. These are 00:24:00.819 --> 00:24:02.940 vital not primarily for seeing the meniscus itself 00:24:02.940 --> 00:24:04.839 because it's soft tissue. Right, x -ray show 00:24:04.839 --> 00:24:07.519 bone mainly. Exactly. Yeah. But they're crucial 00:24:07.519 --> 00:24:10.630 to assess for any concomitant... bony pathologies, 00:24:11.009 --> 00:24:13.150 like fractures, especially avulsion fractures 00:24:13.150 --> 00:24:15.990 near ligament attachments, to identify any loose 00:24:15.990 --> 00:24:18.230 bodies floating in the joint. And importantly, 00:24:18.529 --> 00:24:20.170 particularly in older patients with suspected 00:24:20.170 --> 00:24:22.509 degenerative tears, to assess for the presence 00:24:22.509 --> 00:24:24.809 and severity of pre -existing osteoarthritis. 00:24:25.309 --> 00:24:27.549 This significantly influences treatment options. 00:24:27.910 --> 00:24:30.569 OK. So rule out other things and check for arthritis. 00:24:30.970 --> 00:24:33.930 Precisely. In young patients with an acute meniscal 00:24:33.930 --> 00:24:36.390 injury, these radiographs should typically appear 00:24:36.390 --> 00:24:39.259 normal. Although occasionally you might see meniscal 00:24:39.259 --> 00:24:41.579 calcifications in cases of crystalline arthropathy 00:24:41.579 --> 00:24:45.420 like CPPD, Pseudogout, which can sometimes mimic 00:24:45.420 --> 00:24:48.700 meniscal tear symptoms. However, for actually 00:24:48.700 --> 00:24:50.700 diagnosing and characterizing the meniscal tear 00:24:50.700 --> 00:24:54.880 itself, magnetic resonance imaging or MRI is 00:24:54.880 --> 00:24:57.539 unequivocally the best modality. The gold standard. 00:24:57.819 --> 00:24:59.819 It's widely considered the gold standard for 00:24:59.819 --> 00:25:02.319 assessing soft tissues in the knee when compared 00:25:02.319 --> 00:25:04.799 to the ultimate standard of arthroscopy. It gives 00:25:04.799 --> 00:25:07.809 us incredible detail. MRI has demonstrated impressive 00:25:07.809 --> 00:25:12.210 accuracy, around 93 % sensitivity and 88 % specificity 00:25:12.210 --> 00:25:16.369 for medial meniscal tears, and maybe 79 % sensitivity 00:25:16.369 --> 00:25:19.589 and 96 % specificity for lateral meniscal tears. 00:25:19.829 --> 00:25:22.150 Pretty good numbers. Very good. MRI findings 00:25:22.150 --> 00:25:24.170 that strongly indicated tear include that grade 00:25:24.170 --> 00:25:26.329 3 signal we mentioned, the linear high signal, 00:25:26.650 --> 00:25:28.829 that bright line extending all the way to an 00:25:28.829 --> 00:25:31.529 articular surface, or the presence of a paramaniscal 00:25:31.529 --> 00:25:34.230 cyst. Ah, yes. The cyst often points to an underlying 00:25:34.230 --> 00:25:37.319 tear. It does. It's fluid leaking out through 00:25:37.319 --> 00:25:39.819 the tear. For specific tear patterns, particularly 00:25:39.819 --> 00:25:42.460 those causing mechanical symptoms like locking, 00:25:43.380 --> 00:25:46.380 MRI offers crucial insights. For bucket -handle 00:25:46.380 --> 00:25:49.059 tears, for example, key MRI signs include the 00:25:49.059 --> 00:25:51.819 double PCL sign or the double anterior horn sign, 00:25:51.880 --> 00:25:53.640 where the displaced fragment appears next to 00:25:53.640 --> 00:25:55.660 these normal structures. Clever signs to look 00:25:55.660 --> 00:25:58.019 for. They are. Meniscal extrusion, where the 00:25:58.019 --> 00:26:00.039 meniscus is pushed out from its normal position 00:26:00.039 --> 00:26:02.539 between the femur and tibia, or a ghost sign. 00:26:02.680 --> 00:26:04.960 indicating a loss of the normal meniscal signal 00:26:04.960 --> 00:26:07.480 where the root should be. Yeah. These might signal 00:26:07.480 --> 00:26:09.700 a root tear. Which we know is serious. Exactly. 00:26:10.220 --> 00:26:12.200 So MRI helps identify those high -risk tears 00:26:12.200 --> 00:26:15.859 too. If MRI isn't available or perhaps contraindicated, 00:26:15.920 --> 00:26:18.440 like with certain pacemakers, a CT arthrogram 00:26:18.440 --> 00:26:21.339 with dye injection or even ultrasound and experienced 00:26:21.339 --> 00:26:24.450 hands might be considered. But MRI remains the 00:26:24.450 --> 00:26:27.269 preferred and most comprehensive method. It allows 00:26:27.269 --> 00:26:30.410 us to truly see the tear in 3D, assess its type, 00:26:30.750 --> 00:26:33.069 its exact location, its size, and its relationship 00:26:33.069 --> 00:26:35.670 to the vascular zones. Invaluable information. 00:26:36.109 --> 00:26:38.829 Absolutely invaluable for planning. Okay, so 00:26:38.829 --> 00:26:41.009 once diagnosed, often with that precision MRI 00:26:41.009 --> 00:26:43.769 offers, what's the typical treatment pathway? 00:26:44.150 --> 00:26:46.089 You've already hinted it's not one size fits 00:26:46.089 --> 00:26:48.289 all. It clearly depends on the tear, the patient. 00:26:48.849 --> 00:26:51.460 That's absolutely right. Treatment is highly 00:26:51.460 --> 00:26:53.619 individualized. It depends on a number of crucial 00:26:53.619 --> 00:26:56.839 factors. The patient's age is important, their 00:26:56.839 --> 00:26:58.880 specific symptoms, especially those mechanical 00:26:58.880 --> 00:27:01.980 ones, their activity level and functional demands. 00:27:02.680 --> 00:27:05.420 And critically, the specific type, size, and 00:27:05.420 --> 00:27:08.190 location of the tear. particularly its vascularity. 00:27:08.730 --> 00:27:11.089 That decision matrix can be quite complex sometimes. 00:27:11.950 --> 00:27:14.569 So what's the initial approach usually? Initial 00:27:14.569 --> 00:27:16.890 treatment for an acutely painful swollen knee 00:27:16.890 --> 00:27:19.549 where a meniscal tear is suspected often involves 00:27:19.549 --> 00:27:22.150 the classic rice precipules for acute soft tissue 00:27:22.150 --> 00:27:25.609 injury. Rest, ice, compression, elevation. Exactly. 00:27:25.890 --> 00:27:28.269 Rest from aggravating activities, regular ice 00:27:28.269 --> 00:27:30.450 application, compression with a bandage or sleeve, 00:27:30.789 --> 00:27:33.529 and keeping the leg elevated. Oral analgesics 00:27:33.529 --> 00:27:36.169 like paracetamol and non -steroidal anti -inflammatory 00:27:35.950 --> 00:27:38.569 inflammatory drugs, and asides such as ibuprofen 00:27:38.569 --> 00:27:40.950 or naproxen are commonly prescribed to help manage 00:27:40.950 --> 00:27:43.789 pain and reduce swelling. Bracing or knee sleeves 00:27:43.789 --> 00:27:46.470 can offer some protection and compression. An 00:27:46.470 --> 00:27:48.970 early pain -free knee and ankle range of motion 00:27:48.970 --> 00:27:51.650 exercises are also encouraged, quite early on 00:27:51.650 --> 00:27:54.210 actually. To prevent stiffness. Precisely. To 00:27:54.210 --> 00:27:56.450 limit motion loss and also to help with edema 00:27:56.450 --> 00:28:00.079 control through muscle pumping action. Patients 00:28:00.079 --> 00:28:02.779 are typically advised to avoid exercises requiring 00:28:02.779 --> 00:28:06.299 maximal knee flexion, like deep squats, or using 00:28:06.299 --> 00:28:08.339 things like stair steppers or rowing machines, 00:28:08.619 --> 00:28:10.880 as these can exacerbate symptoms by compressing 00:28:10.880 --> 00:28:13.740 the posterior horns. Okay, so initial calming 00:28:13.740 --> 00:28:16.319 down phase. Then what? Conservative versus surgical? 00:28:16.460 --> 00:28:19.480 Right. For simple tears, particularly those confined 00:28:19.480 --> 00:28:22.339 to that outer one -third, are well vascularized 00:28:22.339 --> 00:28:25.440 red zone. And for many degenerative peers, especially 00:28:25.440 --> 00:28:27.799 in older patients, without significant mechanical 00:28:27.799 --> 00:28:30.190 symptoms. A conservative approach consisting 00:28:30.190 --> 00:28:33.089 of, say, four, six weeks of relative rest and 00:28:33.089 --> 00:28:35.309 structured physiotherapy is a very reasonable 00:28:35.309 --> 00:28:37.250 first line of management. See how things settle. 00:28:37.549 --> 00:28:40.670 Exactly. This allows us to determine if spontaneous 00:28:40.670 --> 00:28:43.210 healing might occur, or perhaps more commonly, 00:28:43.690 --> 00:28:45.710 if the patient can return to their desired level 00:28:45.710 --> 00:28:48.829 of function without needing surgery. Symptoms 00:28:48.829 --> 00:28:51.029 might just settle down even if the tear itself 00:28:51.029 --> 00:28:54.079 doesn't fully heal. In many cases, particularly 00:28:54.079 --> 00:28:56.599 for degenerative tears, non -surgical treatment 00:28:56.599 --> 00:28:58.859 has actually been shown in good quality trials 00:28:58.859 --> 00:29:02.779 to be non -inferior to arthroscopic partial meniscectomy 00:29:02.779 --> 00:29:05.099 in terms of long -term functional improvement. 00:29:05.640 --> 00:29:07.500 That's a really significant finding, isn't it? 00:29:07.619 --> 00:29:09.980 Avoid surgery for many. It is. It's a crucial 00:29:09.980 --> 00:29:12.579 consideration, especially in older patients without 00:29:12.579 --> 00:29:15.539 true locking or catching. It's a common misconception 00:29:15.539 --> 00:29:18.240 that all meniscal tears need an operation. Many 00:29:18.240 --> 00:29:21.079 don't. That's a key message. So when do we shift 00:29:21.079 --> 00:29:23.380 gears and start thinking seriously about surgical 00:29:23.380 --> 00:29:25.700 intervention and what are the primary surgical 00:29:25.700 --> 00:29:27.619 options available? Can you walk us through the 00:29:27.619 --> 00:29:31.019 nuances of choosing one over another? Yes. Surgical 00:29:31.019 --> 00:29:33.099 intervention is typically considered when that 00:29:33.099 --> 00:29:35.700 conservative management fails to alleviate persistent 00:29:35.700 --> 00:29:39.099 symptoms after a reasonable trial, perhaps 6 00:29:39.099 --> 00:29:42.680 -12 weeks, or if the patient experiences significant 00:29:42.859 --> 00:29:45.740 functionally limiting pain, persistent swelling, 00:29:46.380 --> 00:29:48.519 and particularly those debilitating mechanical 00:29:48.519 --> 00:29:51.539 symptoms, true locking or persistent catching 00:29:51.539 --> 00:29:53.900 that significantly impair their function and 00:29:53.900 --> 00:29:56.819 quality of life. Okay. So failure of non -op 00:29:56.819 --> 00:30:00.299 or significant mechanical issues. Broadly, yes. 00:30:00.940 --> 00:30:03.279 The two main surgical approaches we then consider 00:30:03.279 --> 00:30:06.599 are meniscal repair and menosectomy. Repair versus 00:30:06.599 --> 00:30:09.259 removal? Essentially, yes. Meniscal repair is 00:30:09.259 --> 00:30:11.339 generally the preferred option whenever it's 00:30:11.339 --> 00:30:13.599 anatomically and clinically feasible. Why the 00:30:13.599 --> 00:30:15.880 preference for repair? Because preserving meniscal 00:30:15.880 --> 00:30:18.180 tissue is absolutely crucial for the long -term 00:30:18.180 --> 00:30:20.880 health of the knee. Its removal significantly 00:30:20.880 --> 00:30:23.039 increases the long -term risk of accelerated 00:30:23.039 --> 00:30:26.059 osteoarthritis. This is due to decreased cushioning 00:30:26.059 --> 00:30:28.880 and increased force transmission across the articular 00:30:28.880 --> 00:30:31.700 cartilage surfaces. Think of it as sacrificing 00:30:31.700 --> 00:30:34.400 a vital shock absorber. You inevitably put more 00:30:34.400 --> 00:30:36.359 stress on the joint's delicate surfaces over 00:30:36.359 --> 00:30:38.460 time. Right. Preserve the tissue if you can. 00:30:38.859 --> 00:30:41.579 Exactly. The best candidates for repair are typically 00:30:41.579 --> 00:30:45.019 tears located in that vascular red zone, or perhaps 00:30:45.019 --> 00:30:47.779 the red -white zone. Tears shorter than about 00:30:47.779 --> 00:30:50.339 two centimeters. Vertical longitudinal tears 00:30:50.339 --> 00:30:53.400 are often good candidates. and acute tears, ideally 00:30:53.400 --> 00:30:55.480 those less than six weeks old, maybe up to three 00:30:55.480 --> 00:30:58.579 months. Acute tears repaired concurrently with 00:30:58.579 --> 00:31:01.579 an ACL reconstruction traditionally showed higher 00:31:01.579 --> 00:31:04.119 healing rates, likely due to the bleeding and 00:31:04.119 --> 00:31:06.339 growth factors released during the ACL surgery. 00:31:07.220 --> 00:31:09.440 Though, as I mentioned, current literature suggests 00:31:09.440 --> 00:31:12.079 maybe less difference now with modern all -inside 00:31:12.079 --> 00:31:14.500 repair techniques, whether done with an ACL or 00:31:14.500 --> 00:31:18.160 in isolation. Okay. And success rates. Overall, 00:31:18.380 --> 00:31:20.700 success rates for meniscal repair and appropriate 00:31:20.700 --> 00:31:23.539 candidates range quite widely, but are often 00:31:23.539 --> 00:31:27.559 reported between 70 -95%, which is very encouraging 00:31:27.559 --> 00:31:29.440 when it works. That's pretty good. What techniques 00:31:29.440 --> 00:31:31.619 are used? Common repair techniques include the 00:31:31.619 --> 00:31:34.039 inside -out approach. This has often been considered 00:31:34.039 --> 00:31:36.359 the gold standard, especially for posterior horn 00:31:36.359 --> 00:31:38.680 tears. It involves passing sutures from inside 00:31:38.680 --> 00:31:40.859 the joint out through the capsule, requiring 00:31:40.859 --> 00:31:43.680 a small accessory incision medially or laterally 00:31:43.680 --> 00:31:46.079 to tie the sutures down securely. Needs careful 00:31:46.079 --> 00:31:48.839 dissection outside. Yes, you have to be very 00:31:48.839 --> 00:31:52.380 precise, carefully navigating neurovascular structures, 00:31:52.920 --> 00:31:55.640 like the saphenous nerve and vein medially, or 00:31:55.640 --> 00:31:58.420 the common peroneal nerve and popliteal vessels 00:31:58.420 --> 00:32:02.480 laterally. So it's technically demanding. The 00:32:02.480 --> 00:32:05.099 all -inside technique is now probably the most 00:32:05.099 --> 00:32:08.420 common method used worldwide. It utilizes specialized 00:32:08.420 --> 00:32:12.359 suture devices with bioabsorbable anchors. allowing 00:32:12.359 --> 00:32:14.980 the repair to be done entirely arthroscopically 00:32:14.980 --> 00:32:17.559 without that outside incision. Quicker, less 00:32:17.559 --> 00:32:20.500 invasive. Potentially, yes. Though it comes with 00:32:20.500 --> 00:32:23.079 its own potential complications like device breakage, 00:32:23.240 --> 00:32:25.920 anchor pull -out, or even iatrogenic chondral 00:32:25.920 --> 00:32:27.940 injury if the device isn't used carefully. Mm 00:32:27.940 --> 00:32:30.940 -hmm. Tradox as always. Always. There's also 00:32:30.940 --> 00:32:33.140 an outside -in technique, which is useful for 00:32:33.140 --> 00:32:35.920 more anterior horn tears. Generally, vertical 00:32:35.920 --> 00:32:38.019 mattress sutures are preferred biomechanically 00:32:38.019 --> 00:32:40.599 for their strength as they capture those circumferential 00:32:40.599 --> 00:32:43.180 fibers effectively. And healing can sometimes 00:32:43.180 --> 00:32:45.940 be enhanced by rasping or needling the tear edges 00:32:45.940 --> 00:32:48.299 to try and stimulate a bleeding response from 00:32:48.299 --> 00:32:51.279 the synovium. Trying to encourage biology. Exactly. 00:32:51.500 --> 00:32:54.920 Post -operatively, after a repair, knee flexion 00:32:54.920 --> 00:32:57.079 beyond 90 degrees is typically restricted for 00:32:57.079 --> 00:32:59.680 about six weeks. And weight bearing is often 00:32:59.680 --> 00:33:02.099 limited, too, to protect that delicate repair 00:33:02.099 --> 00:33:05.819 site while it heals. OK. So quite a careful rehab 00:33:05.819 --> 00:33:08.599 after repair. What about the alternative meniscectomy? 00:33:08.920 --> 00:33:12.039 Right. Partial meniscectomy. This involves arthroscopically 00:33:12.039 --> 00:33:15.099 trimming away only the damaged, unstable meniscal 00:33:15.099 --> 00:33:18.180 tissue, aiming to preserve as much healthy, functional 00:33:18.180 --> 00:33:20.440 tissue as possible. Just taking out the torn 00:33:20.440 --> 00:33:23.079 bits? Essentially, yes. Smoothing off the edges. 00:33:23.900 --> 00:33:25.660 This is currently the most frequent surgical 00:33:25.660 --> 00:33:28.740 treatment for torn menisci worldwide. It's particularly 00:33:28.740 --> 00:33:31.539 indicated for complex tears, degenerative tears 00:33:31.539 --> 00:33:34.000 with mechanical symptoms, or radial tears that 00:33:34.000 --> 00:33:36.519 aren't amenable to repair, or perhaps for cases 00:33:36.519 --> 00:33:39.440 where a previous repair has failed. And recovery. 00:33:39.920 --> 00:33:42.119 Patients often return to sports or full activities 00:33:42.119 --> 00:33:44.490 relatively quickly. perhaps within six to eight 00:33:44.490 --> 00:33:46.890 weeks following this procedure. This makes it 00:33:46.890 --> 00:33:48.769 an attractive option for those needing a faster 00:33:48.769 --> 00:33:51.869 recovery. But the downside? The arthritis risk. 00:33:52.190 --> 00:33:55.970 That's the major concern. While it's highly effective 00:33:55.970 --> 00:33:58.180 for immediate symptom relief, getting rid of 00:33:58.180 --> 00:34:00.779 the catching and pain about 50 % of patients, 00:34:01.220 --> 00:34:03.799 perhaps more with larger resections, may develop 00:34:03.799 --> 00:34:06.380 radiographic changes consistent with osteoarthritis 00:34:06.380 --> 00:34:08.800 in the longer term. It highlights that trade 00:34:08.800 --> 00:34:11.320 -off between quick symptomatic relief and potential 00:34:11.320 --> 00:34:14.500 future joint health deterioration. Right. A difficult 00:34:14.500 --> 00:34:17.420 balance sometimes. It can be. Predictors of better 00:34:17.420 --> 00:34:19.820 outcomes after partial meniscectomy include being 00:34:19.820 --> 00:34:22.719 younger, perhaps under 40, having normal knee 00:34:22.719 --> 00:34:25.400 alignment, having minimal or no pre -existing 00:34:25.400 --> 00:34:28.199 arthritis visible on x -ray, and having a single, 00:34:28.480 --> 00:34:31.039 simple tear pattern rather than complex degeneration. 00:34:31.320 --> 00:34:33.659 Okay. Are there any other surgical options? You 00:34:33.659 --> 00:34:36.239 mentioned transplantation. Yes. For a very select 00:34:36.239 --> 00:34:38.579 group of patients, meniscal allograft transplantation 00:34:38.579 --> 00:34:40.380 is considered. This is really a salvage procedure. 00:34:40.480 --> 00:34:43.280 Who's it for? Typically for younger active patients, 00:34:43.440 --> 00:34:45.980 usually under 50, who have had a previous near 00:34:45.980 --> 00:34:48.420 total meniscectomy, especially of the lateral 00:34:48.420 --> 00:34:51.139 meniscus, which tolerates removal less well, 00:34:51.760 --> 00:34:54.019 and they must have persistent pain related to 00:34:54.019 --> 00:34:56.679 that meniscal deficiency, but crucially have 00:34:56.679 --> 00:34:59.139 an otherwise stable knee without significant 00:34:59.139 --> 00:35:02.530 arthritis or malalignment. So replacing the missing 00:35:02.530 --> 00:35:05.409 meniscus with donor tissue. Exactly. It aims 00:35:05.409 --> 00:35:07.929 to restore some of the meniscus' function, reduce 00:35:07.929 --> 00:35:10.929 pain, improve function, and potentially prevent 00:35:10.929 --> 00:35:13.989 or delay the onset of osteoarthritis. And recovery 00:35:13.989 --> 00:35:16.349 for that. It's a much bigger undertaking. It 00:35:16.349 --> 00:35:18.750 requires a substantial recovery period, typically 00:35:18.750 --> 00:35:21.469 8 -12 months, for the graft to fully incorporate 00:35:21.469 --> 00:35:25.070 and heal biologically. Return to sports, if appropriate, 00:35:25.289 --> 00:35:27.969 generally occurs within 6 -9 months, maybe longer. 00:35:28.889 --> 00:35:31.190 and long -term results. Long -term follow -up 00:35:31.190 --> 00:35:33.289 studies show generally persistent improvement 00:35:33.289 --> 00:35:35.730 in subjective pain and function scores compared 00:35:35.730 --> 00:35:38.530 to pre -op. However, radiographic progression 00:35:38.530 --> 00:35:40.570 of some degenerative changes is still common, 00:35:41.070 --> 00:35:43.150 unfortunately. And complications like retires 00:35:43.150 --> 00:35:45.690 or extrusion of the graft can occur. So not a 00:35:45.690 --> 00:35:48.349 perfect solution, but an option for some. An 00:35:48.349 --> 00:35:51.650 option in very specific circumstances. Contraindications 00:35:51.650 --> 00:35:53.789 would include things like inflammatory arthritis, 00:35:54.389 --> 00:35:57.110 significant instability, marked obesity, significant 00:35:57.110 --> 00:35:59.889 chondral damage already present, or unaddressed 00:35:59.889 --> 00:36:02.309 malalignment like being very bow -legged or knock 00:36:02.309 --> 00:36:04.710 -kneed. Right. And you mentioned total menosectomy 00:36:04.710 --> 00:36:07.869 is basically historical now. Largely, yes. Its 00:36:07.869 --> 00:36:10.130 outcomes were consistently very poor in the long 00:36:10.130 --> 00:36:13.110 term. Studies showed pretty much 100 % of patients 00:36:13.110 --> 00:36:15.730 developing significant arthrosis at 20 years 00:36:15.730 --> 00:36:18.590 post total menosectomy and 20 % having major 00:36:18.590 --> 00:36:21.969 arthritic lesions even at three years. It just... 00:36:21.739 --> 00:36:24.219 powerfully highlights the absolutely critical 00:36:24.219 --> 00:36:26.920 role of preserving as much meniscal tissue as 00:36:26.920 --> 00:36:29.440 possible whenever feasible. A very stark warning 00:36:29.440 --> 00:36:32.000 from history. This really underscores the immense 00:36:32.000 --> 00:36:34.300 importance of choosing the right treatment for 00:36:34.300 --> 00:36:36.519 the right patient. That bespoke approach, as 00:36:36.519 --> 00:36:38.739 you say. And I imagine that getting the treatment 00:36:38.739 --> 00:36:40.920 right and getting it done in a timely manner 00:36:40.920 --> 00:36:42.960 makes a significant difference in preventing 00:36:42.960 --> 00:36:45.460 those longer -term, often irreversible issues 00:36:45.460 --> 00:36:48.719 like arthritis. Absolutely. It is crucial wherever 00:36:48.719 --> 00:36:52.530 possible to seek appropriate treatment for symptomatic 00:36:52.530 --> 00:36:55.869 meniscal tears promptly. Untreated injuries, 00:36:56.150 --> 00:36:59.150 especially unstable ones, can progressively worsen. 00:36:59.690 --> 00:37:02.489 They can lead to further cartilage damage, significant 00:37:02.489 --> 00:37:05.409 joint issues, and ultimately accelerate the progression 00:37:05.409 --> 00:37:08.670 to degenerative arthritis. We know that the severity 00:37:08.670 --> 00:37:11.289 of degenerative changes is often directly proportional 00:37:11.289 --> 00:37:13.429 to the percentage of meniscus that was removed 00:37:13.429 --> 00:37:16.250 during previous surgery. That's a key clinical 00:37:16.250 --> 00:37:18.989 takeaway for us. More tissue removed equals higher 00:37:19.159 --> 00:37:22.119 future arthritis risk. Delaying necessary surgical 00:37:22.119 --> 00:37:24.820 intervention, especially for tears that are repairable, 00:37:25.219 --> 00:37:27.559 can exacerbate problems. The tear might become 00:37:27.559 --> 00:37:30.739 larger, more complex, or propagate into the vascular 00:37:30.739 --> 00:37:33.460 zone, making it unreparable later. This can lead 00:37:33.460 --> 00:37:36.260 to greater instability and further joint deterioration 00:37:36.260 --> 00:37:39.579 over time. So delay can turn a repairable tear 00:37:39.579 --> 00:37:42.400 into an unreparable one. It certainly can. And 00:37:42.400 --> 00:37:44.840 for younger patients in particular, this cascade 00:37:44.840 --> 00:37:47.500 can result in the need for partial or even total 00:37:47.500 --> 00:37:49.920 knee replacements much earlier in life than they 00:37:49.920 --> 00:37:52.159 otherwise would have needed them, maybe in their 00:37:52.159 --> 00:37:55.539 40s or 50s. That significantly impacts their 00:37:55.539 --> 00:37:57.699 long -term quality of life and ability to remain 00:37:57.699 --> 00:38:00.920 active. It's a stark reminder that procrastination 00:38:00.920 --> 00:38:03.920 or perhaps inappropriate initial management can 00:38:03.920 --> 00:38:06.260 have severe consequences for a patient's future 00:38:06.260 --> 00:38:08.840 mobility. A really crucial point about timely 00:38:08.840 --> 00:38:11.099 and appropriate intervention. So whether the 00:38:11.099 --> 00:38:13.739 path chosen is conservative or surgical, rehabilitation 00:38:13.739 --> 00:38:16.619 is unequivocally the critical next step for successful 00:38:16.619 --> 00:38:19.179 recovery. Could you outline the overarching principles 00:38:19.179 --> 00:38:21.320 and the typical phased approach to recovery, 00:38:21.780 --> 00:38:23.539 highlighting perhaps the distinctions between 00:38:23.539 --> 00:38:26.260 rehab after a repair versus after a meniscectomy? 00:38:26.559 --> 00:38:28.699 Yes, rehabilitation is indeed the cornerstone 00:38:28.699 --> 00:38:31.099 of recovery. You can have the best surgery in 00:38:31.099 --> 00:38:33.780 the world, but without good rehab, the outcome 00:38:33.780 --> 00:38:36.860 won't be optimal. The aims are always to restore 00:38:36.860 --> 00:38:40.380 knee function, strength, and stability. Initially, 00:38:40.800 --> 00:38:43.300 for any symptomatic meniscal tear, whether managed 00:38:43.300 --> 00:38:46.099 conservatively or just after surgery, the management 00:38:46.099 --> 00:38:48.960 focuses on relative rest and avoiding activities 00:38:48.960 --> 00:38:50.900 that strain the knee. Avoiding those aggravating 00:38:50.900 --> 00:38:53.900 movements. Exactly. Squatting, kneeling, twisting 00:38:53.900 --> 00:38:56.039 those closed kinetic chain movements we mentioned 00:38:56.039 --> 00:38:58.840 earlier. Ice therapy is recommended acutely to 00:38:58.840 --> 00:39:01.059 decrease swelling and pain, and the knee should 00:39:01.059 --> 00:39:04.739 be elevated when resting. Early isometric exercises 00:39:04.739 --> 00:39:07.280 for the quadriceps are introduced almost immediately. 00:39:07.460 --> 00:39:10.139 Why so early? To support the joint, minimize 00:39:10.139 --> 00:39:11.880 muscle inhibition, which happens very quickly 00:39:11.880 --> 00:39:14.079 with knee pain and swelling, and prevent muscle 00:39:14.079 --> 00:39:16.800 atrophy. Quads control the knee, so keeping them 00:39:16.800 --> 00:39:19.420 active is vital. These are done without excessive 00:39:19.420 --> 00:39:21.920 stress on the chain itself. As mentioned, patients 00:39:21.920 --> 00:39:24.699 are typically advised to avoid exercises requiring 00:39:24.699 --> 00:39:27.880 maximal knee flexion, like deep lunges, stair 00:39:27.880 --> 00:39:31.199 steppers, or rowing machines. as these can put 00:39:31.199 --> 00:39:34.860 undue stress on the healing or irritated meniscus, 00:39:35.159 --> 00:39:38.099 particularly the posterior horns. Okay, and the 00:39:38.099 --> 00:39:41.079 overall goals? The overall goals are clear. reduce 00:39:41.079 --> 00:39:44.039 pain and swelling effectively, restore full pain 00:39:44.039 --> 00:39:46.619 -free range of motion, improve muscle strength 00:39:46.619 --> 00:39:49.280 and endurance, not just in the quads, but hamstrings, 00:39:49.500 --> 00:39:53.079 glutes, calves too, and importantly, optimize 00:39:53.079 --> 00:39:55.400 neuromuscular coordination and proprioception, 00:39:55.940 --> 00:39:57.880 getting that sense of joint position and control 00:39:57.880 --> 00:40:00.440 back. Right, retraining the whole system. Exactly. 00:40:00.960 --> 00:40:03.179 For non -surgical treatment, success is often 00:40:03.179 --> 00:40:05.659 indicated by minimal swelling, the ability to 00:40:05.659 --> 00:40:07.880 bear weight comfortably without a limp, and achieving 00:40:07.880 --> 00:40:10.719 full range of motion with perhaps only discomfort 00:40:10.719 --> 00:40:13.559 at the very extremes of flexion, allowing them 00:40:13.559 --> 00:40:15.599 to return to their desired activities without 00:40:15.599 --> 00:40:17.539 significant limitation. That makes perfect sense. 00:40:17.760 --> 00:40:20.000 So what does this phased rehabilitation approach 00:40:20.000 --> 00:40:22.059 typically look like in practice, particularly 00:40:22.059 --> 00:40:23.840 thinking about the different considerations for 00:40:23.840 --> 00:40:26.619 a delicate meniscal repair versus a more straightforward 00:40:26.619 --> 00:40:29.699 partial menosectomy? Right. We typically follow 00:40:29.699 --> 00:40:32.239 a structured criteria -based phased approach. 00:40:32.780 --> 00:40:35.119 It needs to adapt based on the patient's specific 00:40:35.119 --> 00:40:37.900 injury, the surgical procedure, if any, and their 00:40:37.900 --> 00:40:40.219 individual progress. It's not just about timeframes. 00:40:40.460 --> 00:40:43.739 OK, phase one. The initial phase, generally the 00:40:43.739 --> 00:40:45.880 first couple of weeks, maybe up to week four, 00:40:45.900 --> 00:40:49.179 six post -op for a repair. This focuses predominantly 00:40:49.179 --> 00:40:51.840 on protecting the repair or letting inflammation 00:40:51.840 --> 00:40:54.380 settle, increasing passive and active assisted 00:40:54.380 --> 00:40:57.159 range of motion carefully, and managing acute 00:40:57.159 --> 00:41:00.030 pain and swelling. Exercises like gentle passive 00:41:00.030 --> 00:41:02.530 knee flexion, maybe wall slides with a good leg 00:41:02.530 --> 00:41:05.289 helps, can be used to facilitate flexion, often 00:41:05.289 --> 00:41:07.869 with specific limits after a repair, say 090 00:41:07.869 --> 00:41:10.909 degrees initially. Once they achieve that comfortably, 00:41:11.429 --> 00:41:14.309 maybe heel slides can replace wall slides, isometric 00:41:14.309 --> 00:41:16.969 quadriceps exercises, quad set straight leg raises 00:41:16.969 --> 00:41:19.190 continue to be crucial for muscle activation 00:41:19.190 --> 00:41:22.449 and preventing that disuse atrophy. Electrical 00:41:22.449 --> 00:41:24.250 muscle stimulation might be employed if there's 00:41:24.250 --> 00:41:26.769 significant quad inhibition. So controlled movement, 00:41:27.070 --> 00:41:30.599 minimal stress. Exactly. And crucially, for repairs, 00:41:31.119 --> 00:41:32.739 there are often weight -bearing restrictions. 00:41:33.519 --> 00:41:35.880 Maybe non -weight -bearing or touchdown weight 00:41:35.880 --> 00:41:38.460 -bearing for several weeks, gradually progressing 00:41:38.460 --> 00:41:41.019 as healing allows. Okay. Intermediate phase. 00:41:41.199 --> 00:41:43.739 In the intermediate phase, spanning perhaps weeks 00:41:43.739 --> 00:41:46.900 3 to 6 for a minosectomy, maybe weeks 6 to 12 00:41:46.900 --> 00:41:50.119 for a repair, strengthening exercises are cautiously 00:41:50.119 --> 00:41:53.329 introduced and progressed. This is where closed 00:41:53.329 --> 00:41:56.110 kinetic chain exercises like mini squats, leg 00:41:56.110 --> 00:41:59.429 presses, step ups can begin. Often once the patient 00:41:59.429 --> 00:42:02.190 can manage basic quad activation exercises without 00:42:02.190 --> 00:42:04.789 pain or compensation. We start light and build 00:42:04.789 --> 00:42:07.880 up. A running program might be initiated. often 00:42:07.880 --> 00:42:10.599 with a walk jog progression on a treadmill, perhaps 00:42:10.599 --> 00:42:12.599 once quadriceps and hamstring strength reaches 00:42:12.599 --> 00:42:15.440 about 70 -80 % compared to the uninvolved leg 00:42:15.440 --> 00:42:18.280 as assessed by functional tests or maybe isokinetic 00:42:18.280 --> 00:42:20.239 testing if available. Right. Need that strength 00:42:20.239 --> 00:42:23.079 base first. Absolutely. Need adequate muscular 00:42:23.079 --> 00:42:25.179 support for the impact of running to minimize 00:42:25.179 --> 00:42:27.960 re -injury risk. Range of motion should be nearing 00:42:27.960 --> 00:42:30.179 full by this stage, especially after menisectomy. 00:42:30.280 --> 00:42:32.340 And the advanced phase, getting back to sport. 00:42:32.519 --> 00:42:35.699 Yes, the advanced phase, from weeks 6 -12 onwards 00:42:35.699 --> 00:42:39.440 for menosectomy, maybe month 3 -6 plus for repair. 00:42:40.139 --> 00:42:42.119 This shifts focus to more dynamic, functional, 00:42:42.260 --> 00:42:45.300 and eventually sport -specific activities. Isotonic 00:42:45.300 --> 00:42:47.159 strengthening for hamstrings and hip muscles? 00:42:47.519 --> 00:42:50.780 glutes, abductors, becomes more intense. These 00:42:50.780 --> 00:42:53.719 are crucial for overall lower limb power, control, 00:42:53.840 --> 00:42:57.159 and stability during landing and cutting. Agility 00:42:57.159 --> 00:43:00.099 drills, cone drills, ladder drills, plyometric 00:43:00.099 --> 00:43:02.599 exercises, hopping, jumping, bounding, or gradually 00:43:02.599 --> 00:43:04.960 introduced once sufficient strength, endurance, 00:43:05.079 --> 00:43:07.780 and control are demonstrated. Track running progresses. 00:43:08.639 --> 00:43:10.619 The progression here is highly tailored to the 00:43:10.619 --> 00:43:13.119 person's individual activity goals. Returning 00:43:13.119 --> 00:43:15.400 to recreational jogging is very different from 00:43:15.400 --> 00:43:17.599 returning to competitive rugby. Absolutely, needs 00:43:17.599 --> 00:43:20.340 careful guidance. Very much so. Now, regarding 00:43:20.340 --> 00:43:22.260 those post -operative rehabilitation differences 00:43:22.260 --> 00:43:24.880 again. For meniscal repair, as we said, a more 00:43:24.880 --> 00:43:26.460 extended period of weight -bearing limitation 00:43:26.460 --> 00:43:29.030 is typical. full weight bearing generally postponed 00:43:29.030 --> 00:43:31.230 for four or six weeks, sometimes longer depending 00:43:31.230 --> 00:43:33.949 on tear type and surgeon preference, to protect 00:43:33.949 --> 00:43:36.250 that delicate repair site. Right, allowing biology 00:43:36.250 --> 00:43:38.849 to happen. Exactly, allowing the stitches and 00:43:38.849 --> 00:43:41.929 the biological healing to take hold without undue 00:43:41.929 --> 00:43:44.170 stress tearing it apart. The emphasis remains 00:43:44.170 --> 00:43:46.789 on managing pain and effusion while carefully 00:43:46.789 --> 00:43:48.949 progressing ROM and strengthening protocols, 00:43:49.489 --> 00:43:51.570 often with those strict limits on flexion initially, 00:43:52.070 --> 00:43:54.190 maybe avoiding deep flexion for three months 00:43:54.190 --> 00:43:57.519 or more. So a much slower, more cautious progression. 00:43:58.039 --> 00:44:00.440 Definitely. The full recovery timeline for a 00:44:00.440 --> 00:44:02.440 meniscal repair allowing return to high -impact 00:44:02.440 --> 00:44:05.219 sport can typically take three to six months, 00:44:05.519 --> 00:44:08.019 sometimes even nine months or longer, for complex 00:44:08.019 --> 00:44:10.880 repairs or revisions. Okay. And menosectomy rehab. 00:44:11.239 --> 00:44:13.920 In stark contrast, partial menosectomy rehab 00:44:13.920 --> 00:44:16.340 is usually much quicker. It often allows for 00:44:16.340 --> 00:44:18.579 immediate or early weight -bearing as tolerated. 00:44:18.760 --> 00:44:21.739 Because no tissue healing is required, it's simply 00:44:21.739 --> 00:44:23.619 trimming away unstable fragments and letting 00:44:23.619 --> 00:44:26.039 the inflammation settle. Return to sports or 00:44:26.039 --> 00:44:28.219 full activities is typically much faster, often 00:44:28.219 --> 00:44:30.599 within three to six weeks for simple cases, maybe 00:44:30.599 --> 00:44:32.920 six, eight weeks for more complex ones, assuming 00:44:32.920 --> 00:44:35.320 good progress with physiotherapy. Big difference 00:44:35.320 --> 00:44:37.659 in timelines. Important to manage expectations. 00:44:38.079 --> 00:44:40.909 Critically important. A patient's overall health, 00:44:41.409 --> 00:44:43.889 their adherence to the physiotherapy plan, their 00:44:43.889 --> 00:44:46.889 motivation, and their pre -injury physical activity 00:44:46.889 --> 00:44:50.070 levels all significantly impact the speed and 00:44:50.070 --> 00:44:52.329 efficacy of recovery, whichever path they are 00:44:52.329 --> 00:44:55.269 on. Furthermore, factors like a balanced diet, 00:44:55.889 --> 00:44:58.349 adequate protein intake for tissue repair, and 00:44:58.349 --> 00:45:00.550 consistent engagement with the exercises also 00:45:00.550 --> 00:45:03.409 facilitate the process. It highlights the holistic 00:45:03.409 --> 00:45:05.969 nature of effective rehabilitation. Absolutely. 00:45:06.090 --> 00:45:08.090 It's a partnership between the patient and the 00:45:08.090 --> 00:45:10.250 therapy team. It really is. OK. We've covered 00:45:10.250 --> 00:45:12.730 a lot on diagnosis, treatment, and that crucial 00:45:12.730 --> 00:45:15.429 road to recovery. Now let's pivot briefly to 00:45:15.429 --> 00:45:18.610 the proactive side. What actionable steps can 00:45:18.610 --> 00:45:21.030 individuals, maybe particularly athletes or those 00:45:21.030 --> 00:45:23.750 in physically demanding jobs, take to try and 00:45:23.750 --> 00:45:26.010 prevent meniscal tears in the first place? And 00:45:26.010 --> 00:45:28.550 then what are the longer term implications if 00:45:28.550 --> 00:45:30.510 these injuries are not appropriately managed? 00:45:30.679 --> 00:45:33.699 Right. Prevention involves a multifaceted approach. 00:45:34.039 --> 00:45:36.159 It's centered on proper training, good conditioning, 00:45:36.579 --> 00:45:38.900 and developing better movement awareness, aiming 00:45:38.900 --> 00:45:41.639 to reduce undue stress on the knee joint. It's 00:45:41.639 --> 00:45:43.880 about building a robust, resilient foundation. 00:45:44.340 --> 00:45:47.019 Okay. Strength training is key. Firstly, yes. 00:45:47.230 --> 00:45:49.269 Strength training. Strengthening the muscles 00:45:49.269 --> 00:45:51.230 around the knee, particularly the quadriceps, 00:45:51.530 --> 00:45:54.309 hamstrings, gluteals, and calves, is absolutely 00:45:54.309 --> 00:45:57.050 crucial. Strong muscles provide better dynamic 00:45:57.050 --> 00:45:59.730 support and stability for the knee joint, helping 00:45:59.730 --> 00:46:02.190 to control movement and mitigate injury risk 00:46:02.190 --> 00:46:04.750 during physical activities, especially those 00:46:04.750 --> 00:46:07.710 involving sudden twists and pivots. Incorporating 00:46:07.710 --> 00:46:10.269 regular strength training enhances joint stability 00:46:10.269 --> 00:46:12.449 and shock absorption. Makes sense. What else? 00:46:12.750 --> 00:46:15.309 Secondly, flexibility and warm -up exercises. 00:46:15.710 --> 00:46:18.969 Dynamic stretches rather than static holds before 00:46:18.969 --> 00:46:21.610 activity and light aerobic exercises as part 00:46:21.610 --> 00:46:23.889 of a comprehensive warmup routine are vital. 00:46:24.510 --> 00:46:26.730 These increase blood flow, improve muscle and 00:46:26.730 --> 00:46:29.030 tendon elasticity, effectively preparing the 00:46:29.030 --> 00:46:31.070 body for activity and potentially preventing 00:46:31.070 --> 00:46:33.449 injuries by allowing tissues to elongate more 00:46:33.449 --> 00:46:35.929 safely under load. Similarly, cooling down after 00:46:35.929 --> 00:46:38.369 workouts helps maintain muscle elasticity and 00:46:38.369 --> 00:46:42.019 aids recovery. Good prep and recovery. Yes. Thirdly, 00:46:42.260 --> 00:46:45.119 proper technique and movement awareness. Education 00:46:45.119 --> 00:46:47.340 on correct body mechanics in sports and daily 00:46:47.340 --> 00:46:50.000 activities is vital. For athletes, this means 00:46:50.000 --> 00:46:51.920 coaching and practicing appropriate cutting, 00:46:52.099 --> 00:46:55.139 landing, and pivoting patterns to minimize undue 00:46:55.139 --> 00:46:58.179 stress on the knee joint during play. Good neuromuscular 00:46:58.179 --> 00:47:02.619 control. Landing softly controlled turns. Exactly. 00:47:03.239 --> 00:47:05.380 For anyone, it means being mindful of awkward 00:47:05.380 --> 00:47:07.659 twisting motions, especially when lifting heavy 00:47:07.659 --> 00:47:10.449 objects or squatting down. using hips and legs, 00:47:10.510 --> 00:47:12.789 not just twisting the knee. Okay. And returning 00:47:12.789 --> 00:47:16.510 after a break. Fourthly, gradual return to activity. 00:47:17.230 --> 00:47:19.050 This is particularly important for our so -called 00:47:19.050 --> 00:47:21.750 weekend warriors or anyone returning after an 00:47:21.750 --> 00:47:24.309 injury or a period of inactivity. Individuals 00:47:24.309 --> 00:47:26.610 should gradually reintroduce high -impact exercises 00:47:26.610 --> 00:47:29.289 in sports, ideally under guidance from a healthcare 00:47:29.289 --> 00:47:31.929 provider or coach. This ensures they avoid sudden 00:47:31.929 --> 00:47:34.309 large increases in training intensity or duration 00:47:34.309 --> 00:47:36.329 that can overload tissues and predispose them 00:47:36.329 --> 00:47:39.429 to re -injury or a new tear. That too much too 00:47:39.429 --> 00:47:42.670 soon is a common pitfall. Finally, lifestyle 00:47:42.670 --> 00:47:46.010 considerations. Monitoring activity levels is 00:47:46.010 --> 00:47:48.570 important, avoiding those sudden spikes in intensity. 00:47:49.219 --> 00:47:51.800 Regular lower impact activities like cycling, 00:47:51.960 --> 00:47:54.320 swimming, or using an elliptical trainer can 00:47:54.320 --> 00:47:56.539 help maintain cardiovascular fitness and knee 00:47:56.539 --> 00:47:59.159 health, support joint stability, and promote 00:47:59.159 --> 00:48:01.800 cartilage health without excessive wear and tear. 00:48:02.440 --> 00:48:04.780 These can contribute to long -term knee resilience. 00:48:05.360 --> 00:48:07.400 And of course, maintaining a healthy body weight 00:48:07.400 --> 00:48:09.820 significantly reduces the chronic load going 00:48:09.820 --> 00:48:12.099 through the knee joint with every step. Right. 00:48:12.239 --> 00:48:14.440 Less load, less stress. It truly sounds like 00:48:14.440 --> 00:48:16.719 a holistic approach to fitness and mindful movement 00:48:16.719 --> 00:48:19.400 is absolutely key for prevention. Now turning 00:48:19.400 --> 00:48:22.239 to the flip side, if these tears aren't managed 00:48:22.239 --> 00:48:24.320 properly either conservatively or surgically 00:48:24.320 --> 00:48:27.019 when needed, what are the potential long -term 00:48:27.019 --> 00:48:29.659 complications patients might face? What are the 00:48:29.659 --> 00:48:31.860 really serious consequences we're trying to avoid? 00:48:32.199 --> 00:48:34.480 That's a critical question and it's the one we 00:48:34.480 --> 00:48:36.699 often have to counsel patients about most carefully 00:48:36.699 --> 00:48:39.280 when discussing treatment options and the importance 00:48:39.280 --> 00:48:42.599 of following through. The most significant long 00:48:42.599 --> 00:48:45.260 -term concern and the one we consistently observe 00:48:45.260 --> 00:48:47.179 in clinical practice and long -term studies, 00:48:47.940 --> 00:48:50.599 is the almost inevitable progression to knee 00:48:50.599 --> 00:48:53.260 osteoarthritis. The wear and tear arthritis. 00:48:53.500 --> 00:48:56.559 Exactly. Studies consistently indicate that individuals 00:48:56.559 --> 00:48:59.139 with significant meniscal tears, particularly 00:48:59.139 --> 00:49:01.639 those where substantial meniscal tissue has been 00:49:01.639 --> 00:49:04.280 removed surgically, have a markedly increased 00:49:04.280 --> 00:49:06.960 likelihood of developing knee arthritis in the 00:49:06.960 --> 00:49:09.369 affected compartment in the future. This can 00:49:09.369 --> 00:49:11.690 lead to severe long -term disability, chronic 00:49:11.690 --> 00:49:14.650 pain, loss of function, and a significant reduction 00:49:14.650 --> 00:49:17.949 in quality of life. As we discussed, the severity 00:49:17.949 --> 00:49:20.409 of those degenerative changes is often directly 00:49:20.409 --> 00:49:22.570 proportional to the percentage of meniscus that 00:49:22.570 --> 00:49:25.849 was removed. Every gram of meniscus counts for 00:49:25.849 --> 00:49:27.710 long -term joint health. That direct link is 00:49:27.710 --> 00:49:30.789 so important. It is. And while surgery offers 00:49:30.789 --> 00:49:34.849 solutions, it also carries inherent, albeit generally 00:49:34.849 --> 00:49:37.909 rare, risks. We have to mention those. Things 00:49:37.909 --> 00:49:40.829 like post -operative blood clots, DVT, or PE. 00:49:41.349 --> 00:49:43.489 Infections, which can be devastating in a joint. 00:49:44.150 --> 00:49:46.510 Or, antigenic damage during the procedure to 00:49:46.510 --> 00:49:49.110 nerves, blood vessels, or even the articular 00:49:49.110 --> 00:49:52.070 cartilage itself. Patients may also experience 00:49:52.070 --> 00:49:54.570 complications related to anesthesia or issues 00:49:54.570 --> 00:49:56.929 arising from the surgical site itself, like persistent 00:49:56.929 --> 00:49:59.789 swelling, stiffness, or wound healing problems. 00:49:59.829 --> 00:50:02.150 Mm -hmm. Risks with any intervention. Always. 00:50:02.360 --> 00:50:05.079 And crucially, as we touched on, delayed intervention 00:50:05.079 --> 00:50:07.199 for tears that would clearly benefit from repair 00:50:07.199 --> 00:50:09.679 can exacerbate existing problems. The tear might 00:50:09.679 --> 00:50:12.380 become larger, more complex, displace, or heal 00:50:12.380 --> 00:50:14.880 in a bad position, leading to greater instability 00:50:14.880 --> 00:50:17.300 and further joint deterioration over time. Right. 00:50:17.420 --> 00:50:20.360 Missing the window for repair. Exactly. And for 00:50:20.360 --> 00:50:22.880 younger patients, in particular, this failure 00:50:22.880 --> 00:50:25.139 to intervene appropriately or in a timely manner 00:50:25.139 --> 00:50:28.119 can result in them needing partial or total knee 00:50:28.119 --> 00:50:30.579 replacements much earlier in life than they otherwise 00:50:30.579 --> 00:50:33.369 would have. potentially in their 40s or 50s. 00:50:33.449 --> 00:50:35.949 This significantly impacts their ability to stay 00:50:35.949 --> 00:50:38.809 active and their overall quality of life. This 00:50:38.809 --> 00:50:41.130 is why our initial decision -making repair versus 00:50:41.130 --> 00:50:44.570 removal versus non -op is so absolutely vital. 00:50:44.750 --> 00:50:47.929 And functional consequences. Functionally, untreated 00:50:47.929 --> 00:50:49.989 symptomatic tears often result in persistent 00:50:49.989 --> 00:50:52.750 pain, recurrent swelling, and those debilitating 00:50:52.750 --> 00:50:55.449 mechanical issues like locking or catching. These 00:50:55.449 --> 00:50:57.630 can significantly impair mobility and overall 00:50:57.630 --> 00:50:59.969 quality of life day to day. These functional 00:50:59.969 --> 00:51:02.150 limitations can then lead to compensatory movement 00:51:02.150 --> 00:51:04.389 patterns limping, avoiding certain activities 00:51:04.389 --> 00:51:06.349 where the patient tries to offload the painful 00:51:06.349 --> 00:51:08.889 knee. This, in turn, increases the risk of further 00:51:08.889 --> 00:51:11.130 injury to other joints, like the hip or the other 00:51:11.130 --> 00:51:13.289 knee, or structures within the kinetic chain. 00:51:13.369 --> 00:51:16.170 A knock -on effect. Absolutely. It can create 00:51:16.170 --> 00:51:19.250 a vicious cycle of chronic pain, weakness, and 00:51:19.250 --> 00:51:22.150 functional decline, often accompanied by noticeable 00:51:22.150 --> 00:51:25.090 muscle atrophy, particularly in the quadriceps 00:51:25.090 --> 00:51:28.659 around the affected joint. This is why a comprehensive 00:51:28.659 --> 00:51:31.460 rehabilitation approach guided by physiotherapy 00:51:31.460 --> 00:51:34.420 is essential not only for acute recovery after 00:51:34.420 --> 00:51:36.820 injury or surgery, but also to address these 00:51:36.820 --> 00:51:39.280 potential long -term functional implications. 00:51:40.079 --> 00:51:43.260 Restoring strength, range of motion, and neuromuscular 00:51:43.260 --> 00:51:46.019 control is key to breaking that cycle. Really 00:51:46.019 --> 00:51:47.679 highlights the importance of that whole patient 00:51:47.679 --> 00:51:50.079 journey, not just the initial treatment. Absolutely. 00:51:50.199 --> 00:51:52.599 Long -term view is critical. This deep dive has 00:51:52.599 --> 00:51:54.679 really highlighted just how complex meniscal 00:51:54.679 --> 00:51:57.860 tears can be. From the initial diagnosis, understanding 00:51:57.860 --> 00:52:00.019 the tier pattern and location through to the 00:52:00.019 --> 00:52:02.000 treatment decision -making, the surgery itself 00:52:02.000 --> 00:52:04.460 if needed, and that crucial long -term management 00:52:04.460 --> 00:52:06.679 including rehabilitation and preventing future 00:52:06.679 --> 00:52:09.440 issues, it strikes me that achieving optimal 00:52:09.440 --> 00:52:12.260 patient outcomes truly depends on a highly collaborative 00:52:12.260 --> 00:52:14.920 interprofessional approach. Could you elaborate 00:52:14.920 --> 00:52:16.739 on the importance of the entire healthcare team 00:52:16.739 --> 00:52:18.739 in managing these patients effectively? Yes, 00:52:18.739 --> 00:52:21.480 you've hit upon a critical point there. For any 00:52:21.480 --> 00:52:24.570 patient with a significant meniscal tear, particularly 00:52:24.570 --> 00:52:27.409 perhaps those presenting acutely or needing surgery. 00:52:28.090 --> 00:52:30.570 Effective management is inherently an interprofessional 00:52:30.570 --> 00:52:34.769 team effort. No single clinician can or should 00:52:34.769 --> 00:52:38.329 try to do it all in isolation. Seamless handovers 00:52:38.329 --> 00:52:40.849 and clear communication are paramount. So who's 00:52:40.849 --> 00:52:43.789 typically involved? Well, it often begins perhaps 00:52:43.789 --> 00:52:45.849 with the emergency department physician or a 00:52:45.849 --> 00:52:48.630 GP for the initial assessment and stabilization. 00:52:48.840 --> 00:52:51.139 maybe distinguishing it from other acute knee 00:52:51.139 --> 00:52:53.639 injuries like fractures or ligament ruptures. 00:52:54.300 --> 00:52:56.400 Then, NERF practitioners often play a vital role 00:52:56.400 --> 00:52:58.840 in the patient's journey, maybe an initial triage 00:52:58.840 --> 00:53:01.059 in some systems, providing patient education 00:53:01.059 --> 00:53:03.440 on initial management and home care, arranging 00:53:03.440 --> 00:53:05.780 investigations, and providing follow -up after 00:53:05.780 --> 00:53:08.889 their initial visit. or postoperatively. The 00:53:08.889 --> 00:53:10.809 orthopedic surgeon is, of course, crucial for 00:53:10.809 --> 00:53:13.489 a definitive diagnosis, often interpreting the 00:53:13.489 --> 00:53:16.050 MRI in context, discussing treatment options 00:53:16.050 --> 00:53:18.010 with the patient, surgical planning, and then 00:53:18.010 --> 00:53:20.030 performing any necessary interventions, whether 00:53:20.030 --> 00:53:22.690 it's a repair or a minisectomy. The radiologist 00:53:22.690 --> 00:53:24.989 is absolutely indispensable for that crucial 00:53:24.989 --> 00:53:27.349 imaging interpretation, providing the detailed 00:53:27.349 --> 00:53:29.909 insights from the MRI scans that really guide 00:53:29.909 --> 00:53:31.769 our diagnostic thoughts and treatment decisions. 00:53:32.059 --> 00:53:35.440 A good detailed radiology report is worth its 00:53:35.440 --> 00:53:38.179 weight in gold. Definitely. And critically, the 00:53:38.179 --> 00:53:40.679 physiotherapist is fundamental, both for leading 00:53:40.679 --> 00:53:42.820 conservative management, guiding patients through 00:53:42.820 --> 00:53:45.219 non -surgical pathways with structured exercise 00:53:45.219 --> 00:53:48.380 programs, and also for providing that comprehensive 00:53:48.380 --> 00:53:51.119 preoperative preparation and, even more importantly, 00:53:51.599 --> 00:53:53.940 post -operative rehabilitation. The cornerstone, 00:53:53.940 --> 00:53:56.699 as you called it. It really is. The physio plays 00:53:56.699 --> 00:53:59.219 a vital role in following the prescribed plan, 00:53:59.619 --> 00:54:02.420 but also adapting exercises based on the patient's 00:54:02.420 --> 00:54:05.119 individual progress, identifying any issues early 00:54:05.119 --> 00:54:07.820 and providing continuous feedback on that progress 00:54:07.820 --> 00:54:10.559 to the orthopedic team, often via the orthopedic 00:54:10.559 --> 00:54:12.980 nurse or directly to the surgeon. That feedback 00:54:12.980 --> 00:54:15.820 loop sounds crucial. It's invaluable. It tells 00:54:15.820 --> 00:54:17.639 us how the patient is actually responding to 00:54:17.639 --> 00:54:20.059 the plan in real time. Are they ahead of schedule? 00:54:20.500 --> 00:54:22.940 Are they struggling? Are they developing complications 00:54:22.940 --> 00:54:26.530 like stiffness or persistent swelling? The orthopedic 00:54:26.530 --> 00:54:29.050 nurse in specialist settings often acts as a 00:54:29.050 --> 00:54:31.849 key coordinator, ensuring seamless care transitions 00:54:31.849 --> 00:54:34.489 between hospital and community, answering patient 00:54:34.489 --> 00:54:36.710 questions, providing education on medication 00:54:36.710 --> 00:54:39.829 management or wound care, reinforcing rehab protocols, 00:54:40.250 --> 00:54:42.130 and keeping the treating clinician abreast of 00:54:42.130 --> 00:54:44.949 all developments. Monitoring for any complications 00:54:44.949 --> 00:54:47.989 or lack of progress between appointments can 00:54:47.989 --> 00:54:51.110 be, yes. This coordinated communication and collaboration 00:54:51.110 --> 00:54:53.610 are absolutely essential because the recovery 00:54:53.710 --> 00:54:56.750 especially after a repair, can often be prolonged. 00:54:57.210 --> 00:54:59.269 It requires consistent effort and adaptation 00:54:59.269 --> 00:55:00.909 from both the patient and the various health 00:55:00.909 --> 00:55:03.769 care providers involved. A unified approach where 00:55:03.769 --> 00:55:07.530 everyone surgeon, physio, nurse, GP, and importantly 00:55:07.530 --> 00:55:09.969 the patient is on the same page regarding the 00:55:09.969 --> 00:55:12.789 diagnosis, the specific treatment plan, the precautions, 00:55:12.909 --> 00:55:15.789 and the rehabilitation goals. This significantly 00:55:15.789 --> 00:55:18.349 enhances care coordination and ultimately the 00:55:18.349 --> 00:55:21.230 patient's long -term functional outcome. Whilst 00:55:21.230 --> 00:55:24.239 most patients, thankfully, do achieve a satisfactory 00:55:24.239 --> 00:55:26.440 outcome with good function returning to the knee. 00:55:26.900 --> 00:55:29.460 This is profoundly impacted by the team's ability 00:55:29.460 --> 00:55:31.820 to work together efficiently and effectively, 00:55:32.360 --> 00:55:35.019 putting the patient truly at the center of that 00:55:35.019 --> 00:55:38.030 care pathway. A fantastic summary of the team 00:55:38.030 --> 00:55:40.409 approach. What an incredibly comprehensive deep 00:55:40.409 --> 00:55:43.349 dive into meniscal tears. From the intricate 00:55:43.349 --> 00:55:46.269 anatomy and that crucial insight that the vascular 00:55:46.269 --> 00:55:49.449 zone truly dictates the destiny of a tear right 00:55:49.449 --> 00:55:51.670 through to the tailored treatment pathways and 00:55:51.670 --> 00:55:53.909 the absolutely vital role of rehabilitation. 00:55:54.610 --> 00:55:56.690 It's so clear that understanding these injuries 00:55:56.690 --> 00:55:59.570 requires a really nuanced and detailed approach 00:55:59.570 --> 00:56:01.710 for any medical professional dealing with knee 00:56:01.710 --> 00:56:04.530 pain. You've really demystified a complex area 00:56:04.530 --> 00:56:07.320 for us. Thank you so much for sharing your invaluable 00:56:07.320 --> 00:56:09.239 insights with us today. It's been incredibly 00:56:09.239 --> 00:56:12.000 enlightening. It's been a real pleasure. The 00:56:12.000 --> 00:56:14.079 more we can foster this kind of shared understanding 00:56:14.079 --> 00:56:16.699 across the medical community regarding such prevalent 00:56:16.699 --> 00:56:19.039 conditions like meniscal tears, the better we 00:56:19.039 --> 00:56:20.860 can truly serve our patients and work together 00:56:20.860 --> 00:56:23.260 to improve their long -term outcomes. Indeed. 00:56:23.579 --> 00:56:26.519 I couldn't agree more. And for you, our listener, 00:56:26.639 --> 00:56:28.880 we sincerely hope this deep dive has provided 00:56:28.880 --> 00:56:31.380 you with a clearer, more comprehensive understanding 00:56:31.380 --> 00:56:34.460 of meniscal tears, hopefully equipping you with 00:56:34.460 --> 00:56:36.260 the knowledge to approach these common cases 00:56:36.260 --> 00:56:38.199 with greater confidence and precision in your 00:56:38.199 --> 00:56:40.760 own practice. Perhaps it's prompted a deeper 00:56:40.760 --> 00:56:43.059 look into a particular classification of tear 00:56:43.059 --> 00:56:46.059 you encounter often, or maybe a specific rehabilitation 00:56:46.059 --> 00:56:47.820 phase that you will explore further with your 00:56:47.820 --> 00:56:50.260 therapy colleagues.
