- How to assess the posterolatearal corner on MRI. In this video, I show you the anatomy of all posterolateral corner structures (PCL) that you need to know and how to simplify the assessment of knee MRI for posterolateral corner injuries. It does not have to be complicated.
The three important structure you need to assess are the:
1. lateral collateral ligament (LCL)
2. biceps femoris tendon
3. popliteus tendon
Smaller structures you can asses are:
4. poplitefibular ligament
5. meniscopopliteal fascicles
6. fabellofibular ligament
7. arcuate ligament

Brilliant. I've never seen an arcuate ligament in my life.
some say not to use the term at all, so you probably did not miss anything at all. different paper call different structures the arcuate ligament.
I always found it a daunting task to evaluate the posterolateral corner structures particularly after I had learned that posterolateral corner injury is considered as a surgical emergency by some orthopedic surgeons. Your video made me feel more comfortable. Thanks.
Cool
Have been struggling with search for this arcuate ligament since a long time. We have this checklist style reporting and I hate filling the posterolateral corner section of the report.
Great video, Dr. Agten
That is good to read. Any other structures you are struggling with? Just fishing for some ideas
Doctor Please more posts about shoulder impingement ...
The topic made incredibly simple! Thanks a ton!
This was super helpful and will definitely help me improve my reports.
Thank you!
Cool. Thx
Thanks a lot.
You are the best!
nice ppt thank you
Thanks a lot.. great disambiguation
Glad you liked it
Many Thanks.
Great job. Ty four your efforts
Thanks
Very useful video. In one MSK Ultrasound course someone wanted to teach us how to find arcuate ligament. How weird!
Really nice videos with examples!:)
Thanks! 😃
Nice lecture!!!
Glad it was helpful!
Great video..thank you :)
Thx
Excellent ♥️
Thank you! Cheers!
Thanks for the great lecture Dr. Agten. Can you please help me differentiate OPL and arcuate ligament .
I loved this video as it made it a lot easier for me to understand my own MRI. I was wondering, in the event of a high grade lateral collateral ligament tear, but the remaining supporting lateral ligamentous structures are normal, is it common practice just to reconstruct the LCL, or do a complete anatomical reconstruction of the posterolateral corner including the politeus tendon and the politeal fibula ligament?
That is more a question for a knee surgeon.
i laughed at your comment 'so stupid'🤣. Totally agree with u it is. But as a surgeon we only want to know FCL or some call it LCL, popliteus and PFL. These are structures that can be reconstructed. PFL is needed yea.
👏
Great as usual. Do you have a video on MCL? also seems confusing the classification system (superficial, middle, deep vs superficial and deep) and different attachments. I think it can make a nice, informative yet quick video!
I'll consider it
I'll add it to my list
@@DrChristophAgten great, looking forwards to!!
Colon or large intestine ulcers can be seen in ct scan?
When you are confused about finding a ligament like the arcuate ligament , they confuse you more by other structures like finding the geniculates vessels ......... the potero latéral corner was nightmare for me ...........;
interestingly enough at ECR in the Level III knee session, the arcuate ligamet was predominantely featured again, without giving clear anatomy------- still confused :D
@@DrChristophAgten LOL, the guy from NY , confuse me more with the RAMP lesion and tutti quanti ; found the wrist for sport injury very well donne though .
I liked when U said a stupid, it is really stupid
Hello sir ,My mother 52 years old. The doctor took an MRI scan and said that the swelling of the membrane on the lower side of the spune was affecting the blood flow in the veins of the right leg. The doctor said that the solution can be treatef with laser treatment. Is there ant other way?
SIR WHAT IS STRENGTH OF MACHINE WHISE IMAGES ARE DISPLAYED HERE
Honestly I still feel difficulty in interpretation of arcuate ligament in my 10 years of radiology practice
Yes. Because it doesn't really exists and everybody things if something different. 😉
Arcuate ligaments: An enigma to all radiologists... but of questionable importance. Leave it to beaver.
Hello,
I wonder if you are open for sending you dicom files to investigate it.
I'm suffering from issues in the posteror pain which isn't showing anything - HOWEVER, there dial test is considered positive (with 5 dagrees).
It's been a year and half since my injury and none can indentify it (I have downloaded the MRI but it's clearly isn't so much meaningful for me).
Cheers,
Mor
I offer second opinions through www.aristra.com
Particular identification of arcuate ligaments is not clear.
because there is no such thing or everybody thinks it is something different.
