As a man who has torn my ACL,medial&lateral meniscus and patellar tendon and now has arthritis, it felt like you were inspecting my knee lol thanks skateboarding
At wht age after acl tear u got arthritis
Lol same same but Rugby 🥲
@@dhanapriya1021 22-25 (had surgery at 21, I’m 27 now)
@@dhanapriya1021 you can get arthritis at any age. But when you injury a joint it's more likely to happen. It's your body's way for compensating for an injury. Like bone spurs in joints. I have both in my left knee from years of running.
All of the above but with a permanent dislocation of the patella causing my leg to bend out of alignment..all caused by myself on a motorcycle having a head-on collision with a vehicle.
(Edit: Didn't expect all the likes, support and well-wishes! Thanks everyone. In a weird way it helps to know I'm not the only one.)
In a motorcycle accident 10 years ago I was going 40mph and someone turned out in front of me like I didn't exist.
I hit their hood and things didn't go well. Completely severed my right knee's ACL PCL and LCL. Stretched my MCL and the artery.
Dislocated both knees and snapped my left femur. 5 breaks below the knee on the right shin.
They told my family they were going to amputate but I was lucky to have one of the best bone trauma surgeons in all of California on call that day.
Leg is still here but I can't run and have limited range of motion from excessive scar tissue. Glad to be alive and still have the leg :D
Broo i can't imagine what that was like😬
Wow
@@Sizzle.7 I can tell you that anyone who dies from serious injury likely only felt a second or two of the pain before it turned off. Shock and adrenaline is a hell of a thing.
@@seanahern9511 Good point
*This* close to having an epic bionic leg. In all seriousness, you’re very lucky. My dad was stopped at a light on his motorcycle and got hit behind by a car going 40 mph because the driver was on their phone. He broke a couple ribs and vertebrae, and also suffered a brain bleed and a collapsed lung. He’s also starting to get some sort of atrophy in his legs. Despite this, he’s mostly alright now. He still has some pain every so often and he’s very stubborn since his brain was damaged.
It’s strange he didn’t break any more bones, considering he was 57 at the time of the accident and wasn’t very active
I’ve been a highway patrol officer/accident specialist officer for 10 years now and let me tell you that the most painful, non-lethal accidents are when people have their feet up on the dash while driving. The car crashes, and both of their knees are completely hyper extended. I’ve seen some where the leg is bent backwards at nearly 70 degrees. Moral of the story is don’t put your feet up on the dash when in a moving vehicle.
Or the knees being smashed into their face
Fold like bologna
Shhh.... Let natural selection does its things...
That REALLY should be common sense even without hearing stories about horror accidents.
Srbija!!!
As a retired Muay Thai fighter I now have pretty bad arthritis in both of my knees. When you are in your 20s you really don't think of the problems that your chosen sport is gonna lead to when you are in your mid 40s.
But why ,shouldn't conditioning strengthen the joints?
@@fabioooh this is like Sharpening a knife, once is gonna make it sharper, Sharpening it hundreds of times is gonna Chip away at the metal, until none is left to sharpen. (correct me if my assumption is wrong)
@@neon9165 doesnt make sense
@@neon9165 or at least, I didnt get your example
@@fabioooh conditioning strengthens the bones and muscles, no amount of conditioning is gonna save your from the amount of wear and tear you go through the years of training.
I had a friend who tore both their acl’s during a football game, cannot imagine the amount of pain they had to go through.
This is the last I place I thought I would see you in lol
@@silverdragon9504 True
Strangely enough someone I know had an acl with no pain, just instability, couldn't put much of her weight on it. Tore it jumping on a trampoline. Apparently she heard a pop when she landed from a jump and couldn't stand after that.
P0o9
@@iamzyz That's not really that strange, in fact torn cruciate ligament (either anterior or posterior) often doesn't really hurts. Of course, the trauma itself is painful, but after a while - not so much. Instead this, what your friend described, is what people generally report: feeling of instability when walking plus general "I feel that there is something wrong with my knee, but can't tell what exactly". That's academic knowlegde, but also once I have met a girl who was living with torn PCL for a year or so and she was mostly alright. She have it repaired later, of course.
Back in the early 90s I was in a car accident that resulted in a total EDIT FOR CORRECTION [ changing "hypertension" to "hyperextension" ] Acl and Pcl were toast. First they tried to repair it with muscle tendons taken from my thigh muscles. Those stretched out. Then they tried cadaver ligaments. That resulted in staph infection. Finally they drilled through the knee and used Goretex rope with screws in each end to hold it in place. It worked well. 3 years ago they had to replacement knee because my cartilage was gone. Same doctor who did the original knee surgery did the replacement and said he was surprised as the Goretex was still tight and strong as when he put it in. Replacement knee is working great btw.
Whoa, you mean a simple (not simple?) car crash caused you to suddenly have high blood pressure?
@@adventureoflinkmk2 It must have been a very stressful car crash!
@@AceNinja2112 must've been, I've been in a few scrapes myself and my hypertension hasn't gotten any worse
I’d like to have my feet removed and replaced them with blades…
Hellova journey man.
Hyperextention of the knee was sadly inevitable for me. I have Ehler’s Danloss Syndrome, and my knees just dislocated about a year apart just walking in my house when I was still in my teens. This was just the first of many other joint injuries. My elbows hyperextend also, since I was a child. Now in my late 40s, my fingers, ankles, and hips dislocate randomly with just the wrong motion. So painful.
I’m so sorry you have to deal with that terrible challenge .
You are not alone! I’m a zebra sister with hEDS!
That sucks! I have hypermobility but no EDS, luckily. Hang in there. 😢
Is there nothing that could help the joints not be so mobile like braces on the joints?
Eds here too. My trouble spots are ribs, one hip, and a subluxing shoulder. Oh and the jaw from hell.
As a person who had a full achilles tendon rupture that required surgery, this really hits home. My range of motion of my ankle is STILL severly restricted after years of rehab and daily ankle mobility exercises. The only silver lining is that I am not a professional athlete but it has impacted my workouts and my favourite leisure activity of playing football (soccer).
Thank you as always for the videos and I wish you all the best.
And to those who are fighting through rehab and struggling through an injury, just do your best and keep a support system around you to remind yourselves that things will get better.
Peace!
@PKD Orion First Kobe was a supreme athlete in great shape compared to us mortals and very strong. Kobe made the 2 easy important shots flat footed and then got out while the pain wasn't severe [adrenaline]. I fully ruptured my left achilles tendon when I was training for a job. It was raining outside when the front of my foot wasn't secure on the slippery step and my weight went backwards down, fully rupturing the tendon. I fell and felt a good gap at the tendon. I first thought I sprained my ankle which I've done before. I didn't want to miss my training class so I got up, the pain wasn't too bad but when I walked my heel would just drag since the tendon wasn't connected.
I didn't say anything and really faked it when I walked there to hide the injury fearing I'd lose my new job, I was young. I didn't have insurance at the time but went to a doctor 2 days later. He put me in a boot that was tilted so I was really tippytoe [making the tendon connect better] and I used crutches. I didn't lose my new job and was like this for 4 months, then went to a normal/flat boot for 3 months. I never did rehab or daily mobility exercises and I'm fine with full strength and motion plus no pain at all. My left calf muscle is just a little smaller than my right b/c of atrophy. Most people do get surgery but sometimes there's a risk of complications when they cut you open.
@@pkdorion4059It helps when you are on steroids (for pain, more muscle everywhere to give you more balance, you dont lose focus etc)
And yes, every athlete is on steroids, and yes they take it for recovery and that reason you described. To push through situations, where normal people would quit. Also, they have an extremely healthy and effective training plan, so that combined with steroids make you do some crazy stuff.
I know from first hand experience
I played ice hockey and have hundreds if not thousands of falls with no injuries. About 10 years ago I was standing on ice and my left foot slipped and I partially tore my right MCL! Damned of all things!
Yep, I’ve fallen hard so many times while roller blading with no issues but step out of someone’s way on a bus and bust my knee.
My husband did the saaaaame thing
Funny similar story my jui jitsu instructor been teaching the art for 4 decades not so much as a staved toe. Tore his lower back muscles taking his Xmas tree out the loft 😆😆😆
Torn my cycling on rainy morning and slipped been a shitty 6 months
I was diagnosed at 17 with
Chondromalacia patella when I was seventeen years old. WORST thing for me, but, I have had a disc removed, cadaver bone added in the 'cage' & much more done. So, pretty sure I have degenerative stuff all over.
I know I desperately need both knees replaced.
You always present very clear, thorough information so we can really learn facts. Thank you.
Have a beautiful weekend.
Wish you well and good luck finding appropriate replacements ❤️🩹
@@prapanthebachelorette6803
Thank you.
Chondromalicia can be treated with Physical Therapy, as well as wearing a patella centering brace. Knee replacement is honestly reserved for patients that are 65 and over. Trust me. You don't want to do it when you are young.
Have had RA since I was 15. Had my first Knee replacement at 30, and need next one soon I'm currently 31.
@@dxmthebeast3800
I'm 63.
Both knees gave out a week ago. Pain was horrendous, & I was in a locked room. My adult kids were unable to help me. Degeneration of both knees. At this point, I can't wait to have one, or both knees done. 🌻
I'm glad you explained the hyper mobility. I've dealt with it, and injuries thanks to it my entire life.
me too
Me, too! I have Ehlers Danlos Syndrome
I have a complete inability to hyperextended.
Blew left ACL, twice then the right one
All skiing... that was more informative than any of my knee surgeons.. wow your videos are Great . THANK YOU
some people never learn what not to do huh 😂 adrenaline junkies are hilarious
Going through the actual names of the tendons vs the colloquial names was very helpful. After which I couldn't help but notice that "blow out" seems to be the colloquial term as well as the accepted medical term for various knee injuries

Blow out is just rupture.
I've had two slipped patellas in two years once at 16 and 18, (one on each knee, both of them with one torn ligament and and parts of the sesamoid bone splintered from the slipp, symmetry yay😆)
This video was extremely interesting and i got to understand the english names of these parts of my knee, since I am neither a medical student nor American.
Amazing video as always 👏
I went to kick a rugby ball once and missed. Even the small amount of hyper extension caused severe pain for several weeks
This was so interesting!! I just had knee surgery a few weeks ago to remove 4 loose bodies that were about 1cm in size each. That pain was awful, so I can't even imagine what the injuries you described would feel like. So sorry for anyone who's suffered from any of those.
I've had both knees replaced due to arthritis. Was in lots of pain for years. During joint replacement both the acl and pcl are removed. Knees are good now.
How long was the recovery?
@@nickbardan3867 I have had both knees replaced 8 months apart. Recovery was less than 3 months for both. Do the work (therapy & exercises) afterward and you will be so thankful you had the surgery!
Are you able to run or play sports after that?
As someone who developed arthritis really early and had my acls and pcls from both sides compromised due to inflammation, this video hurts deeply
I have become a real fan of this channel for the strait up no nonsense and no bs information. THANK YOU. When the content such as this for example is presented, I instantly ask myself "what could a person do or focus on to strengthen the knee area as the first line of defense in preventing an injury?" Since I already trust and respect the information here, having a link or better yet a short do's and dont's list would be amazing. Thanks again.
I have learned so much watching this channel. You gentlemen are the absolute best at teaching Human Anatomy. Thank You for all of your hard work.
At 10 years old I tore mine to the point that I could feel when standing my whole knee separate. You could feel thè joint move from each other. They would put a cast on it for two months. Then a day later it would reinjury. Ended up off and on in a cast 3 years. Painful and scary.
When I was the same age, I was at this day camp and this girl slipped while running on a grassy surface and started screaming and holding her leg below her knee. I saw what looked like a bone bulging out under her skin; it made me sick and I thought I was going to pass out. The camp counselor straightened her leg out again, and when we went to pick her up the next day, we were told that she was in the hospital with a cast on her leg. Sounds like the same thing you had. Back then (the late 50's) they used to call that an abnormal knee. I was pretty intrigued when I got over being sick.
I shuttered just reading your comment...ouchie!
Happens to me every month
How i still have a leg
I dont know
😰
Eww 😩😖
The landscaping in my garden looked superb, 3 different types of paving went so well together...except for....a small 2m x2m square of paving slabs which didn't quite go. Decided to paint them grey with exterior floor paint, lovely job.
Once wet they were like a skating rink and even worse when someone 🙄 had left the hosepipe laying around. I went ar5e over tit tearing the tendon from the patella. It was the most painful thing ever, apart from fracturing my back after a helicopter crash in the army.
The orthopaedic surgeon though decided not to operate as part of the tendon was still attached.
Took it easy for a few months and was back in the gym tentatively doing leg extentions, the tendon had grown back itself needing no surgery..
I broke both of my ACLs. That's why I am here and I want to say this guy really makes me understand what exactly I have lost.THANKS!
I'm going through treatment for a grade 2 ACL and medial meniscal tear. As much as the scans and explanations from the pros have been really good, watching this video was like looking at my own knee injury (although my injury is on my left side). I feel like I've learnt even more. Thank you Justin
I tore the LCL&MCL in my knee both at the same time, that was the most pain I've been in ever, and I had 3 C-sections.😣
Gosh, that’s a big confirmation that this injury is no joke 🥺
How tf did you do that and how is your knee now?
@@SimonAPOz car accident, I'm not too sure how they both ended up torn, I think it was the way my knee was stuck for a while(I think like 2 hours or longer) I had to be cut out of the car.
I was in a knee immobilizer for 6 months after surgery, now I walk with a limp, and cain.
@@prapanthebachelorette6803 yeah it wasn't fun at all. Now 8 walk with a limp and cain. Never get into a car with someone that's been drinking.
My twenties was a nightmare.
Yeah but you haven't had a kidney stone
I’ve had surgery for my torn meniscus in my left knee, had it stitched back together and a year later i had to get another surgery to trim it. Next I had surgery on my right knee for my torn ACL and torn meniscus, had my ACL replaced with my hamstring and had my meniscus fixed. Now i’m waiting to get 2 more surgery’s on my femur because i’ve been feeling alot of pain on both of my later meniscus from me having Knock-Knees and after that hopefully i’m all good. I’m only 18.
I felt bro my left knee is killing me been kinda nervous to go the doc don’t wanna hear I need more surgery 🤦🏾♂️
I find this helpful as I’m going to have total knee surgery soon 🤩
Fantastic introduction to the skeletomuscular anatomy of the knee. I really enjoy this more anatomy class style of video - it's not as focused on rote memorization, but an understanding of the system.
I have watched many of your videos, even while eating lunch, and really enjoy them. This is the first one that made me ill. Just thinking of a knee blowing out the ligaments or dislocating a kneecap, Shivers!
I've been battling arthritis in my knees since I was twelve, resulting in completely destroying my meniscus, having three surgeries to attempt repair, and endless pain. All four condyle surfaces are ground up from bone on bone contact. No replacement for me because I'm allergic to all metals, so I've been a guinea pig for different things like stem cell implants and later this year, we're going to attempt a cadaveric graft.
Ouch! I had a fractured knee 30+ years ago. I can't imagine the pain you deal with.
I have this problem too. There was a time I literally couldn't walk from so much pain, but being young, nobody believed me 😢 Every few months I get a very strong medication for pain, but it's just so expensive 😭 I feel you
@@amandaromeiro7896 I'm 47 and have walked with crutches or a cane since 2013. Insurance once declined my surgery request because I was "too young to be diagnosed with osteoarthritis." I'm not sure how I wasn't too young at 12, but was at 40.
I, too, have battled arthritis in my knee as a result of a knee injury in my teen yrs (torn medial ligament & patella misalignment-> chondromalecia). Several surgeries later & I’m finally pain free thanks to a bone/cartilage graft donor from a 13 yr old- thanks to the family’s generous & gracious gift ❤️! I really hope that the cadaveric graft works wonders for you!! Being in constant pain from bone on bone surfaces is so exhausting & hard.
I hope everyone knees get better ❤️❤️
At 33 I've got post traumatic arthritis from a knee injury while I was 20. My ortho who specialized in knees and was one the choice doctors for OU sports programs said I had one of the worst injuries he'd seen since college. He was amazed I walked in with the aid of a knee brace but nonetheless I had a destroyed knee in his words. I tore decimated my ACL, tore the MCL and PCL with grade 1 and 2, where my LCL connects to the fibula had broke the fibula but still connected to the LCL. My meniscus were destroyed and to top it off I cracked my femur. Did this with the help of motocross all from a single nasty crash of a near 100ft triple. When I hit the ground I went to tuck n roll, guessing my right inner toe of my boot caught ground first twisting my right knee inside the knee brace which broke aswell. Went to get up immediately collapsed but wasnt in serious pain yet due to adrenaline. Ended pushing my bike off the track and loaded up before driving my self to the er with a small water melon sized knee. Really fun time.
Very terrible story
I was a victim of a home invasion. I fought the two bad guys until my knee gave way. I was forced to walk on my injured knee in order to get away. My tibia shot forward so I had to hold it in place while walking and screaming in pain. Turns out I sustained a bucket handle meniscus tear that was so damaged that the surgeon removed all of it. Also, 60% of my ACL was torn, although that was never addressed during surgery. That was three years ago, I still can’t walk. I’m only 49. I think I’m ready for TKR or a.357 healthcare plan.
The 357 plan caught my attention. Hopefully things work out for you. I do keep a gun near me when watching TV. (Kids are gone) Just in case.
Go for ACL reconstruction, and afterwards do some stem cells injections and you will be great
Pain make you wanna put a .357 in yo head.
I wish you health brother
u ever think about having the leg removed and learning to walk on a prosthesis? i know a guy who had his left leg removed (just above knee) after multiple failed knee surgeries, he now not only walks again, but he learned how to clutch with it (dude is a hardcore driver, no automatic cars) and he drives better than most people with two legs.
i got into a car crash and the dashboard slammed my knee into my femur, shattering my femur. also had a PCL avulsion injury that fractured the tibial spine. i can pop my knee out of place because something didn’t heal correctly and it’s the funniest thing ever seeing people gag at it lol
That's quite the party trick
to clarify: my doctors and i are trying to figure out why my leg healed wrong. i have a plate and a dozen screws that makes it impossible to get a clear view of the ligaments/tendons. my doctor currently suspects my pain is from the plate and screws irritating my IT band. the only way to see if there actually is a problem would be to have surgery again and we just don’t think it’s worth it at this time
when surgery was done to repair my femur, the surgeon didn’t see any ligament injuries and my orthopedist determined the PCL avulsion injury, tibial spine fracture, and fibular head fracture all happened post surgery.
My knee also dislocates very easily. But when mine does it is extremely painful and I can't walk on it for at least a week.
@@misseselise3864 is your pcl fixed now?
Wow,that was such an amazing mini-lesson!Would you guys consider making a similar video with a knee that has had a full knee replacement?Both of mine have been replaced,and I think it would be so interesting to see how the body would heal into the metal parts.Love your channel!!
So, you're the Bionic Woman! 😁
I have type 3 Ehlers Danlos Syndrom and i have frequent joint injuries due to it. hypertensions and dislocations have lead to me needing hip and shoulder surgeries. i havent had to have knee surgeries yet, but i can feel that the many hypertensions are catching up to me. this video was very informative and helped me to be even more thankful for all my PTs and stability braces 🥳
Oh man, I’ve had 5 knee surgeries and I had to pause this - multiple times..in order to finish! 🙌🏼🙌🏼🙌🏼 nice work! Love your stuff!!!
I have personally torn my meniscus in half at 12 with 2 surgeries at 13 and it’s been the HARDEST injury I’ve ever had to come back from especially being an athlete. Knee injuries are the worst no matter what kind of injury it is
How are you now. Had 2 repairs in my meniscus but still failed
@@Khalito66 i never made a full recovery. i took a year off from sports to recover in 2014 and went back to playing basketball at 15 and ended up having to quit sports all together because doing things like running causes a lot of soreness afterwards and it constantly is in pain. im expected to have a knee replacement later on in life
@@mak3582 god damn
With my joint condition (Larsen's syndrome) just my normal standing puts my knee in a slightly hyper extended position. For me however the most problematic this is that my right knee also tends to bend/dislocate to the left (aka think adding an additional motion to the knee, back and forward like normal and now excessively sideways), I can definitely say that it's rather unpleasant
Both of my knees do that due to a birth defect. For me it isn’t Larsen’s syndrome, that I know of anyway. My knee caps only about 70-75% of the size they should be. It hasn’t happened in a long time, but I could be doing the simplest thing and have a knee cap dislocate. To say that it’s unpleasant is an understatement.
My knees do something similar and tho I was never given a diagnostic label for it, the surgery ultimately didn’t help reduce the dislocations I have in a radical way. I’ve always thought I might have some variation of EDS, but have never heard of Larsons, so I am definitely going to do research into that now, see if it is something worth investigating with my doctor.
I just have achy hypermobile joints, but my knees are constantly bent the wrong way. I can also slip them around sideways! its not really that pleasant though, you're right.
@@mcrchickenluvr The most "fun" one is when you're leaning to get something and then your knee decides it wants to go else were. I'm used to randomly just falling over because of my ankles but that way of going over takes the biscuit
@@hannahherrmann4921 All my other joints are fine when they dislocate (though some like my shoulder now sound like a cement mixer), my knee and my left thumb are the ones I can say are definitely unpleasant, plus I have an exceedingly high pain threshold so that's saying something XD
Thanks for doing this video. I’m due to have knee replacement on my left knee. It wasn’t a slow process I saw coming. I moved houses and did not think I’d overworked myself, but the next morning told me I had. After a week of not walking, or even moving, without pain, and then a dr diagnosed me as arthritic, meniscus gone (showed me the X-ray & the difference between the two knees), and needing a new knee. Seeing the anatomy of the knee, and this knee in particular, as it showed me exactly the issue I have. Fortunately this type of cadaver inspection, does snot bother me in the slightest and I find all your videos. Fascinating. Good job & thanks!
I'm getting my new knee on the 12th of March. Same boat
Great video! As one who has had knee problems & multiple knee surgeries, it’s neat to be able to see an actual knee joint. Thanks for such great content!
These always make me hungry!
Hahaha
LMAO
I know, watching these videos makes me hungry too, it's so weird.
Lol
Had a minor ligament tear few years ago; knee was swollen for about 3 days. Oh! the inconvenience. With that I started learning about ligaments.. tendons.. etc etc.
This is a cool video to see. I fractured my patella once and tore my acl and mcl recently. I also have osgood-schlatters. My knees are 50 and I’m not even 20 year.
I work in ct and mri thanks for showing more anatomy. I sometimes read report and I forget some of the things I studied. Good refresher. Thanks
I tore my ACL in half (grade 3) a couple years ago when I crashed on a bicycle. They told me that at 50 years old, they don’t usually repair it. I almost totally forget that I even have this injury. Every now and then if I move in a funny direction, my knee gets a bit wonky for a second - but it doesn’t cause me to fall. They did tell me that I can no longer ski.
Yes it was! I fractured the bone from the knee to the foot (tibia)and tore some ligaments. I was in a leg cast from my toes to my butt for almost two months. Now when I straighten my legs my left leg goes further back then the right. I had just got a cast off my fractured ankle on the same leg that same year. I was like 13 at the time. But the knee injury was the worst pain I've ever felt to date. I'm 49 now.
How's it now? Did your got torn ligaments?
this was VERY informative thank you! I've been trying to learn more about the knee and you using that cadavers knee helps me visualize much better😊
Amazing ! Would love you guys to do an episode showing the machinations of the ankle.
So interesting I hurt my knee in October 2020 and still hurts. I work for a pt and we work on it all the time. Knees are so hard. There is so much going on there! Thank you for the information. You are a wonderful professor
I was a gymnast and actually tore my ACL, partially MCL, and both menisci by catching the bar going backwards and hooking my knee (causing me to hang from the bar with that leg). Still gives me problems 6 years later.
I’m facing double knee replacement within the next year. This was very informative.
After a massive injury last year to the right knee (grade 3 ACL and MCL, grade 1 PCL, meniscus partially torn/lifted, gracilis and friends torn), I'm watching this with flashbacks and cringing. But I can't stop watching. I love anatomy!
Thanks for sharing your wisdom with the world, guys!
Currently dealing with compound TPF, patellar ligament rupture, ACL rupture, MCL rupture, PCL tear, and both meniscus torn (flipped internally). 4 surgeries abd 5 months later, I've only got 0-40° of ROM.
MRI in 2 days to see about more surgery. :(
Thanks for the educational video. FML.
Hang in there.
Wow. good luck.
I have Hypermobile Ehlers-Danlos Syndrome and I've had to have an MPFL Reconstruction with cadaver ligament. I went from 8 years on crutches with braces to being able to walk independently. The hEDS also required me to have a Fulkerson Osteotomy during the same process(more or less an alignment job on my kneecap) and I never thought I'd be able to walk, much less go up a flight of stairs. Science is amazing.
EXCELLENT! Using cadaver parts to explain anatomy is the best! Looking forward to more videos.
The remarkable teachings of a wonderful doctor! Cheers!
I was ran over by a car, seven years ago. And I got my right-knee PCL severed as a result (Luckily I wore a helmet, and that saved my life). But since the one-year recovery on therapy (and also luckily, the ligament repaired without surgery) I noticed some restricted movement and some pain, espacially then it's cold. Now with your video I understand a lot more about the injury itself, and the impact that it has on my life. I deeply thank you.
Same. I never had surgery on PCL too, and I believe it healed itself. However, I now have this range of motion where I’m able to push my lower legs back. Does yours too?
@@dnlgbrls no it doesn't. I have a lesser range of movement, can't kneel or crawl =(
Great video Justin, i wonder why i felt a phantom pain in my knee while watching? Keep up the good work my friend.
All my life of being around sports i heared of my peers tearing they acl and never really understood how bad it is, until now. What a great channel.
I had a MPFL Knee reconstruction and boy i was in so much of pain when it happened but kudos to my surgeon and physiotherapist getting me back to walking 😊
I have hEDS and issues with my left knee since childhood. This video went a long way in helping me to understand what might actually be happening in that knee when it locks in place at a 90° angle if I bend a certain way. I think it may be something to do with the ACL or PCL, which makes so much sense with my collagen being extra stretchy!
Thank you so much!
Have you all ever covered connective tissue disorders?
I have heds as well and while just standing my knee will sometimes hyperextend backwards and it hurts but thats life. Probably explains my early arthritis. I also just have generalized pain in the knees. Id love to see him cover more joints like this.
Same here!
They can sublux and lock when just sitting still!
Have hyper extended quite a few times when i was younger and dancing.
Painful!!
I had reactive arthritis on my right knee. Probably infection on one of the ligament. One of the worst period of my life, suffered anemia and full body weakness and was bed ridden for 4 months. I am back to normal, 2 years later, but lost my quadricep muscles strength. Still working on it.
I suffered for years with my knees. I recently had bilateral knee replacement surgeries. It’s wonderful! NO MORE PAIN!!!!!!
I love this channel. I was explaining this to a patient who blew out his knee playing rugby.
ruptured patellar tendon victim here. all docs i dealt with called it tendon. it ruptured in the middle not off the bone. it was shredded, like crab meat is what the ortho told me after. took maybe 4-5 years to get back near 100% rom.
Incredible you did get there in the end
I have hyper mobility and about 2 years ago I hyperextended my knee when I slipped in the shower. Took me half a year to recover properly. The irony is that my hyper mobility likely saved my ligaments from tearing. Still one of the worst pains I’ve ever experienced. Don’t hyperextend, kids.
Same and several of my joints are unnaturally flexible. I have to consciously stand straight or else my knees get painful from the extension. At only 20 i get pain from walking and my knees crack a lot when simply bending.
This was so interesting to watch. I've suffered with hypermobile ehlers danlos syndrome all my life and both my knees/legs hyper extend it was natural for me for years to stand on my legs while they were bent backwards . I was just always told that's normal with my condition. It has left me with chondromalacia patella which has now advanced to moderate to severe arthritis and some deformity along with muscle loss of the vmo. This video is the first I've watched that shows what's being going on on the inside thank you.
Your videos are helping me to take care of my hypermobility disorder! Knowing how my body works means I can DIY my dislocations and visualize the bones, tendons, and ligaments. No wonder my knees are so slidey!
My ACL, MCL and LCL are still torn (Grade 3) following a motorbike accident and my PCL is damaged, more stretched than torn (Grade 1). I also have limited Meniscus therefore part of my Fibula and Tibia are touching and i can get a lot of pain from it. There is probably a lot of scare tissue which would explain why my knee doesn't bend at all. Whilst my knee is pretty much fucked i am hoping for a full knee replacement rather than an amputation. Purely because my other side is amputated below the knee.
Hi, this was super helpful, I think I discovered why my knees hurt. Years ago I had an abusive coach, I ran cross country and kept running through pain. I stopped running afterwards. I remember one doctor telling me my pain was psychological. 4 horrible years later without being able to walk or run without pain I came across this video. I think I damaged my lcl and mcl. It explains the buckling of my knees, the pain, the inflammation that just wouldn’t go away. I’m finally seeking medical treatment. To anyone out there, if it hurts, stop. Don’t bother trying to prove yourself to anyone. Take care of yourself
I love your videos, just recently I had a work accident where my femur was snapped into and I'm still recovering proper movement and feeling within my leg below the knee
Some *phenomenal* acting on the rugby stock footage shots at the start of the video. My dude at 00:10 does a glorious air-tackle move.
I hit my knee bad yesterday and I curled up on my bed for like ten minutes in pain.
I feel like a big baby now after watching this
I hit my patella hard during an offroad bike race last weekend and I was on the ground rolling in pain for 10 minutes as well. Got up and finished the 76 miles afterwards though
Thank you! As a 32 year old who's starting to feel pain in both knees, this video helps me see what's going on inside them.
Have you ever made a video about cracking knees? My right knee is almost always cracking when I bend/flex it. If I put my hand on it I as it moves, I can feel something is scraping in there. Bone with bone I guess.
Tell your doctor
I’d be more inclined to think it’s potentially hardened/scarred tissue than bone on bone. Bone on bone is an unbearable pain. Continuous crepitus (cracking) can come from soft tissue issues.
When I go upstairs, my knees sound like someone squeezing bubble wrap.
Falling down and forward in a less-than-graceful dismount from a twin Huey...broke both ankles, damaged knee cartilage and ligaments, jammed both femurs so hard they tore soft tissues around the hip from the bone, and torqued the sacral spine, damaging both SI joints. Amazing ACL replacement using sterilized cadaver tissue, titanium clip and biodissolvable screws made my right knee better than it was before. Hip surgeries involved tacking down detached labrum to the bone, shaving bone off the femur necks (which got thicker reacting to the damage) removal and replacement of synovium, resurfacing bone in the hip, etc., etc. What they did to put me back together (over a 20 year timeframe) was simply amazing. Told me at 21 that i wouldn't be walking at 35 and I was sparring til age 47 and walking with a cane at 57 (nerve damage) but I am still thrilled overall.
My son has Marfan's and along with Marfan's he has connective tissue disorder. His "knee cap" kept on moving in such a way he needed surgery because the muscle would not restrict back in place. Not sure if I explained it correctly but he needed surgery on both knees.
Great video for the commen people like myself that wants to know in case of any emergency situation.
Thanks for sharing
Восхищён вашей лекцией. я русский врач травматолог. Давно пытаюсь донести своим коллегам данную патологию... если есть возможность, сделайте лекцию по "костной реконверсии" по мрт снимкам
My knees feel weak watching this.. 😥
I used to wonder why the knees seem to break down so easily but the intro of the video really made things make sense. My worst knee injury was doing some serious damage to my knee cap by splitting it open, my doctor says my left knee has the age of a 45 year old man now. Which is really gonna suck in another 20 years lol even now whenever it rains I get pain going across it and every year I have to get calcium injections to keep it from splitting apart again anyway enough of my major bodily trauma very informative videos you do here I wish we had these when we were learning about the muscular system in highschool
I tore my MPFL and afracture also I had 2 surgeries ,while playing TT. Knee joint has very special value in my life since I got to know its value .I’m doing great after rehab , back to normal ;)
I did grade 3 ACL, MCL and POL all in one go while rollerblading, it was so strange looking down at my knee seeing it bending in the wrong direction. I knew as soon as it happened that it was bad. 5 months post surgery and the continued pain is very frustrating.
@Jodie Leigh I’m 6 months post ACL surgery with still some discomfort, how do you feel now ?
@@Johnny-ie8dt I'm still in alot of pain, working with a Exercise Physiologist, which is helping but I've recently had an MRI which has shown that the tunnels created for the grafts have not healed so I'm facing more surgery possibly. It's been a very long process. I hope things are progressing better for you.
I have had a hyper extended knee in both my knees a couple times throughout my life. Although it has never required surgery, every time my knees were hyperextended, it felt like my knee was on fire. I could technically walk after I sustained the injury, but my knees would hurt for at least a week and there was a dull pain in them for a couple weeks afterward. They both seem fine today tho but idk what mechanical problems I will have in the future.
In middle school I was running in the halls and slipped and hyperextended my knee, it bent my tibia and now one leg is forever taller than the other, likely other problems to come later in life too.
Thank you- excellent presentation.
Just had ACL reconstruction surgery in January this year on my left knee. Grade 3, complete tear. My surgeon was incredible, and I was walking without crutches in 10 days. I tore it while demonstrating a wheel kick for my karate students. Twisting motion caused it to snap. They used cadaver tissue for my procedure. Try blowing out your ACL on a gymnastics floor, falling to the ground while your leg starts facing the wrong direction, and then NOT crying in front of two dozen children under 16 🤣
I'm made of spare parts, bud!
Glad to hear you came out ok.
@@comeoncarebear thanks! Me too lol
I just had ACL surgery on my left knee too, in December and also had a grade 3 tear! I was walking right after my nerve block wore off. But I also had many months of 'prehab' beforehand.
@@bree12345 I didn't change my daily routine at all after the injury, which definitely helped. I also (against Dr's advice) forced myself to do things 4 days after surgery that I probably shouldn't have. Not weight bearing or anything, but trying to lift my leg under it's own strength with the brace still on. Got those quads strengthened up real quick! I started PT 3 weeks late and already had 109° of motion. Now it's just learning to live with the repair, and dealing with the large numb spot on the front of my leg lol
Glad to hear you recovered well! They way they do these surgeries and the recovery time nowadays is astounding
@@lambofmetallica Okay, so I am also dealing with the large numb spot on the front of my leg as well. My Dr seems unbothered by it... Is yours improving at all? What does yours say about it?
Until I took an arrow to the knee.
As a guy with several surgeries on my knees this was interesting to watch. I had a general understanding of knee anatomy but this gave me a much better understanding.
I have Ehlers Danlos Syndrome and have to wear special braces at time when my knees are hyperextending. It’s not fun and very painful. Very informative. It has explained a lot to me about my condition. EDS is a connective tissue disease just like he said.
Thanks for showing an intact and well-defined articularis genu, Justin.
Videos are amazing and have helped me understand my body a lot. Thanks heaps
This is crazy to watch after completely tearing my acl, pcl, and mcl playing college football a month ago. Lucky I had a lateral dislocation and not a hyper extension dislocation like described in the video. I have a 6 hour reconstructive surgery towards the end of January to reconstruct all 3 ligaments. No more football for me but hopes to at least make a full recovery to run and lift weights again.
Thankyou for this video currently going through rehab for a acl tear
Any chance of getting a similar video but about the shoulders, clavicula, shoulder blades and all its complexity with ligaments and tendons?
Thanks! Love your videos! ❤️
nice, simple explanations...good work!
This video is facts, had my pcl and plc reconstructed, my knee cruches while going up steps now.
Thank you for this. As a ex SASR person in Australia in 6 yrs l have had 2 hip replacements plus in the last 4 months 2 knee replacements. It will take a lot of will power to recover because lm 65yrs old now and VERY tired 🙂
We studied the knee a couple of weeks ago and it was one of my favorite anatomy classes. I wished for more and was kinda sad that I probably wouldn't see a knee piece again like that. Then I discovered this video, I'm happy it looks just like the one in our lab :-)
Hi! Hope you are doing well
I love anatomy. Thank you for teaching us .
Thanks for sharing the information !
One this video was absolutely amazing and great for my highschool project I have, secondly now I'm even more scared of running and damaging my body even though it's my favorite hobby I think I'll stop for a month.😥
