An additional information, patellar tendon is a thick and stretchy ligament. It's easier detach it from tibia then snap it. ACL is a range restriction ligament, made to maintain stability of your knee. So the first to suffer from overload. Pretty fun format, let's see some soccer, skiing and fall mechanisms.
Firstly I was noticed he didn't scream, so very unlikely he has severely injured himself. You can see its as if his muscles give way in a fashion faster than humanly possible so its not faked. The noise you hear is a dislocation followed by an immediate relocation of the joint
@@jonmolina948 The opposite, you should train your ligaments to not be fragile enough to break. But of course not hard enough so the same won't happen to you
After watching many of these videos, I initially thought ACL because of the tibia shift. Then I talked myself out of it based on the fact that there didn't seem to be a telltale athletic movement associated with the injury. Then I felt silly for second guessing myself seeing as I have no real medical knowledge and should just go with the simple answer. Excellent format and interesting video Dr.
As a first semester nursing student, this helps a lot with thinking critically about what was going on, what caused the injury, and why. I really appreciate the videos! Please keep doing this series!
@@MikeBarbarossa Old school Physical Therapy myth for sure on the leg extension being terrible. It can be in the rotation. The APTA even wrote up about this exercises a couple years ago. I used to think it was terrible as well but it's not as bad as we once thought. Cheers!
I guessed the ACL tear. When I saw the injury the first time, I remembered your calling out the video of the wide receiver having that forward pop of the tibia. In this case, I can't tell whether the tibia really moves forward or whether it appears to move forward because everything else has popped backwards. The braces seem to be holding the lower leg in place, so the tibia wouldn't really move at all.
@@BrianSuttererMD i’d like to second this- i’m a premedical student at a supposedly top 10 ranked premed school and my biology teachers (especially my development and physiology teacher) have absolutely sucked. They dont teach lectures, they just give us videos and they arent engaging or able to explain things clearly either. I’m certain you would be a better teacher than anyone at my school right now based of teaching style alone, and i would encourage you to consider it ag some point
And this ladies and gentlemen is why some of us come up and give you tips when we foresee what will happen. Unfortunately most people take offense and end up like this man.
Watching the first 10 seconds, my guess is patellar tendon rupture. Edit: In hindsight, the correct answer makes sense. It just seemed like such an extreme translation in the tibia and violent rupture, I thought it was something bigger giving out. Great video.
You had the right mindset and Brian said it. Either something broke (bone) or something ruptured (ligament). I was mainly thinking that since his leg was fully straight and he was bending backwards, that had to be a lot of stress on the ligaments in the knee. Also, with him covering patella ruptures from NBA players, I didn't see a deformity in the knee so I didn't want to guess that. This is gonna be a fun series.
keep these coming!! i'm already a big fan of this soon to be (hopefully) new series! I originally guessed Patellar tendon rupture, but your breakdown and explanations made perfect sense. Thank you for always teaching us in exciting, new ways!
Thank you for the upload Dr! Poor guy I hope he makes a full recovery! I guessed at the start it would be a: ligament; tendon, muscle injury (above the knee leg muscle) or a combination of the three. I have not studied anatomy for decades & never in detail but hey thank you for making me a detective :::)) Peace & Love!
I’ve decided to comment just looking at the full speed video to make it a bit harder on myself. I feel like I can see the tibia shift forward during the ‘snap’ which implies an ACL tear to me, as his leg seems to have lost the ability to keep his tibia from swinging forward. Either way, love the new video idea. I’m a med student so I usually try to guess what’s going on first anyway, and I feel like this channel has helped give me a better handle on a lot of MSK injuries that I would sometimes struggle to identify in the past. Keep up the good work doc!
@Lagdarr As not a med student who could only watch the first 5 seconds of the video before “nope”-ing out I just gotta say thank you for your intellectual and emotional sacrifice. Just finish med school, I believe in you
This is awesome man! Do more! I think it’s super knowledgeable to know peoples injuries before they are diagnosed. That way they aren’t killed being brought to the hospital
Love this format! As a Sports Chiropractor and high school sports medicine teacher, I use your videos frequently to visually demonstrate the injuries we discuss in class. I appreciate your consistent discussion of anatomy, mechanism of injury, and treatment as it mirrors and reinforces what I teach in class. Keep them coming!! BTW, I called ACL tear:)
At first I was thinking platella dislocation but once I realised that the the tibia popped out anterior the way it did, I immediately screamed ACL tear 😅 Great concept Doc, keep it coming!!
I was able to guess the injury correctly based on a few of your other videos I watched, lol. I was initially drawn to your videos for the MMA content, now I find myself watching injury breakdowns for sports I don't even follow! This new style is another great expansion!
First thing I thought was, 'ACL 100%'. Dr. Sutterer has taught me well. (The shift in the tibia, the pop, it looks so similar to other videos of ACLs that have been covered on the channel!)
I've seen enough of your super informative videos to have guessed this 100% right, and even the reasoning why. But I gotta say, this extra sprinkle of detail you showed on this one actually showing exactly why the quad would cause the patellar tendon to pull the tibia forward...you're taking my armchair quarterback diagnostic skills to a whole nother level! Love this extra level of detail on this style of vid.
I have been dealing with an acl sprain for a couple months and this one was obvious to me after all the doctors have done explaining it to me. This was another good demo!
For being “just” a massage therapist I was totally pumped when I was right haha. From just watching the clip my first thought was the patellar tendon rupture but after hearing you break it down I knew it had to be an ACL, love it!
This is a great video idea! Please keep it up! I study PT so it helps me think critically. I think the same applies with anyone else studying or just having an interest in the mechanisms that cause orthopedic injuries.
I knew ACL tear instantly just by looking at that position, waaay too much weight leveraged over the fulcrum point(his knees) as he over extends backwards his quads buckle under the weight so his ACL tears because it's around the fulcrum point
My guess is ACL from the tibia shift! Edit: also thought could be the tendon as well with the eccentric firing but didn’t see much movement from the quad muscle Loved this video!
Current DPT student and immediately identified anterior translation of the tibia and thought ACL. So many different mechanisms to create anterior translation!
Wow great video. As a physics student I definitely appreciate the explanation of the forces and torque in play. IMO its definitely a great tool to have to understand anatomy and movements better.
I feel like I've watched enough of these videos to be confident in calling that an ACL tear. The shin seemingly popping forward is a dead giveaway for me. Edit: Whew, really happy my confidence paid off! Great video as always doc
Really love this idea and concept for a video. Being in PT school it definitely challenges me and teaches me a lot. I tore my acl in 2020 and was told to never do quad extensions again, you kinda have that same motion here, instead of your torso being stationary while doing a sitting quad sets, your legs are stationary. Either way you do it, it puts enormous tension on that acl as you said. I initially said patella tendon rupture but after explanation and remembering my past from the injury it makes a lot of sense!
Really nice video please do more of these! I am a physiotherapy student and I think this is a great teaching method and your reasoning and explanation as the video continues is a great way to learn, it is much better way of teaching in my opinion (at least from a learning perspective) than just going through the video and explaining what happened. It forces you to think and learn instead of just saying what happened, which is still really good information and useful, but this is nicer to learn from.
I wouldn’t even classify it as a sissy squat, I believe he thinks he’s doing a core/back extension or something of that nature. The weight is just fuel to the fire.
I thought it was a patellar tendon rupture. I figured it wasn’t a quad tear - the injury looked like it clearly took place at the knee, but I made sure to watch to see if you would say an ACL tear. Sure enough I got my answer 👍 Love the idea for guessing the injury as you explain it first. Great work again, Doc!
I'll subscribe for videos like this! This is an educational format which invites us to not just listen to a presentation of information but to use the video to evaluate using the knowledge we have and see why we might have been correct or missed something you caught. I personally did see the shift of the relation of the tibia and femer. I didn't notice the forward travel as much as the downward shift of the femer till pointed out. I thought it had something to do with a supporting ligament rupture but wasn't sure which. Great video!
In the slow mo I can see the tibia move forward really quick which from my understanding is the same motion in the lachman test so I am going to guess an ACL tear. I think it is a tear because of that pop (credit to Doc for mentioning that). This style of video is very fun - unless you are the person in the video! hopefully he recovers fast!
ACL tear, because ACL is mainly responsible for preventing anterior translation of tibia. The upper cushion and lower cushion in the leg has formed an anticlockwise coupling force on tibia while the ACL has been stretched with the eccentric contraction of the sissy squat.
Initially I thought patellar tendon rupture or acl at full speed. In slow motion that immediate anterior shift of the lower leg made me believe it was the acl. I love the explanation about how the quadriceps concentric contraction added to the anterior force causing the tear. My questions are: Is it more or less common to tear the acl with an added rotational force? Would the menisci possibly be compromised as well given the sudden shift under load?
it has to be ACL tear. as ACL prevents the anterior translation of the tibia. Right at the moment of the injury, the moment arm of the quadriceps is the smallest, the CG is the most far out. then the ACL takes up those force. it is under too much tension that it pops.
As a student of sports medicine I was able to guess ACL tear first with a patellar tendon tear as my second guess. Seeing that ventral articulation of the tibia in relation to the femur is a high probability of ACL injury. I wouldn’t program this exercise to any personal training clients ever.
Good evening Doctor Sutterer. Presently I'm a university faculty member teaching course work in our Health and Exercise Science Department. Prior to this, I was an head athletic training at the university level for 30 years dealing with all aspects of sports performance and injuries. I wanted to thank you for your content and the educational opportunities you provide to myself and my students on a daily basis. Your work is much appreciated and I encourage all of my students each quarter to subscribe to your channel.
Writing this as I watch: Looks like a pretty clear patellar tendon rupture. Large snappy sound under eccentric loading of the quads match’s the MOI. You can also see a little window-shading happening too
Cool video aspect!! Got it right because of your most awesome educational videos!!! Thanks!!! .....and yes, it's cool to confirm that we're learning from your videos by diagnosing the injury!!!!
That's the coolest video idea ever. I love it 👍. Btw I guessed ACL. The doctor's always did the lachmann test on me, when I injured my knee on the soccer field. (luckily I never had a torn ACL) I'm starting med school in February and your videos are great to hype me up for my future 😅.
Quad /patellar rupture vs acl tear As always, great video! Addendum LOL: In addition to the quadricep contraction, when his body is parallel to the floor, that would create the longest lever arm, for max tension on the ACL, opposed to the other ranges of motion
I think it's a cognitive deficit brain injury. How else would someone think this movement is a good idea? I'm thankful he filmed it for our edification.
As a non med background guy but I've watched enough of your videos, I immediately thought ACL because of the way his lower leg shifted and ACL is my go-to like on House the first guess was almost always Lupus. I like these, too!
I’ve torn my acl and had it operated. The doctor always use the same nanuever in this video to hold my knee in place, move my tibia back and forth to test out the acl. I immediately knew this was acl, possibly quad tear as well
It's obviously an ACL tear. The apparatus set up is kind of like a high-intensity Lachman's test which is used here in India to diagnose ACL tears at first glance/before the MRI.
At the beginning of the video I first thought quadriceps tendon… When you gave a moment to guess I went to patellar tendon… Good to know my guessing was along the right path of wrong answers, at least! 😂Great video!
Going waaaaasy back to my nursing school days, i was thinking a knee CL injury of sorts due to the immense strain this "exercise" puts on the knee and it's components but wasn't sure. I was also wondering if it could've been a muscle tear or something too. But ACL makes sense, thanks doctor for the brain exercise
The first watch I immediately thought "son los ligamentos cruzados" (spanish is my mother language). As I didn't knew the name of those ligaments in english I keept watching to see the answer and now I now a lot more about injuries and medical terms in english. Thank you, great vid.
Appreciate the support on the new format!! Link videos below that I should do in future episodes

Acl tear. The tibia relocates after the tear.
No cheating! Let me know if you like this new style of video :D
I love it! Greetings from MX
Yeah I love it
It was awesome!!
Really like this type of video
As a pre-physio student this is perfect. Thanks!
i thought it was a patellar tendon tear, surprised it was an ACL tear.. as a recovering ACL recipient, this hurt SO MUCH to see 30 times
Same. I was almost 100% sure it was a patellar tendon rupture lol
I didn’t know what it was, but I guess I’m skipping legs today.
Oh my! 👀
Never tore my acl but this hurts me too

it was clearly acl, the patellar tendon rupture is out because of the patella stays in place afterwards.
It would have been easier if he was upright and attempted to walk. Just watching that joint collapse was enough evidence for me.
As a first semester nursing student, this helps a lot with thinking critically about what was going on, what caused the injury, and why. I really appreciate the videos!
Please keep doing this series!
Also, if you ever see this, please consider going into teaching at some point. You'd make an amazing instructor!
Good luck with school, it’ll fly by and next thing you’ll know you’ll be interviewing for residency 🎉
Why? Stupidity thats why tbh
ACL. I'm an athletic trainer.. We literally had a class where we watched different injury mechanisms... This is gonna be a fun series of videos!!
That movemen mimickes the terrible leg extension. Very hard on the knees, and replicates no real world movement

He was really testing that knee joint. I never heard it snap like that. At least when you’re squatting you can dump the bar to save further damage.

I had guessed PCL. Bad habit of associating ACL ruptures with knee hypertension.

Hey Brian could you possibly check out the eye injury that happened in PFL MMA yesterday ? It’s absurd
ACL tear 100%
And he is doing sissy squats abysmally
I wouldn’t even classify it as a sissy squat, I believe he thinks he’s doing a core/back extension or something of that nature. The weight is just fuel to the fire.
Oh man. This one, the double quad tear during squat, the pec tear on incline bench. Burned into my brain.
Nailed it! I like this new guessing game! Do more of these please!
Doc you gotta do it again. I did guess acl tear based on that shift in the tibia but I wanna see another one of these

Awesome video! Definitely keep these coming! I’m striving to be a PA specializing in orthopedics!
2:32 , because of the anterior movement of the tibia in relation to the femur, ACL might’ve been ruptured on the upward movement of the sissy squat.
Quad /patellar rupture vs acl tear
As always, great video!

In addition to the quadricep contraction, when his body is parallel to the floor, that would create the longest lever arm, for max tension on the ACL, opposed to the other ranges of motion

That's just it, he wasn't thinking.
@@Yeomannn hahahahhaahaha, great reply 🤣

I would also point out that the calf pad is a little low if you ask me...this might've been why there was added stress to the joint.
The first watch I immediately thought "son los ligamentos cruzados" (spanish is my mother language). As I didn't knew the name of those ligaments in english I keept watching to see the answer and now I now a lot more about injuries and medical terms in english. Thank you, great vid.
Love this style of video. Everyone likes to play a doctor.
Thanks
Loved the video, even though I missed it by judging this a pattelar tendon rupture. Looking for more in the future!
Love this! Do more of these videos please 🤗
This was really cool and educational. Thanks, doc!
Great video as always love this new type of video and most likely gonna be a complete tear of the Anterior Cruciate Ligament
I did get ACL. Only other consideration for me was quad tendon rupture but didn't see the quad snap back.
Damn that sound was crazy. Poor guy
Please more of these man!
