Se hace la rotación externa tanto en la maniobra Varo como en la del valgo ya que los ligamentos colaterales (medial y lateral) ambos se tensan en dicha rotación. Mientras que los ligamentos cruzados "frenan" la rotación interna.
Both test (Forced Valgus - and forced Varus) are made with external rotation because this increase tension in the colateral ligaments (Medial and lateral). While for the internal rotation the cruciate ligaments makes the "stop" (End Fell).
Hi Pablo, you don't necessarily want maximal tension in the collateral ligaments. To stress them and to test for pain it's okay, but not if you want to feel for the degree of joint gapping. For the same reason, you don't do the Lachman test or anterior drawer test in maximal internal rotation to test for the ACL.
Short, educating, no bullshit. Cant ask for more
Thanks, this is what we strive for!

i got MCL injury.. its been 3-4 months .. i can walk and do normal things all fine..but when i try agility traning, squats, bend my knees and walk for a long time it pains.plz help me
+Yunesh Sitoula Hey Yunesh, it´s impossible from distance to tell what is causing your pain. So my advice would be to see a physiotherapist in your region to have a look at your knee. Cheers, Kai
thank you
No worries
Thanks
Thank you for guide

Thanks for the clarification!
Thanks 👍
so in both varus and valgus stress test we externally (laterally) rotate tibia
Thank you so much
You’re welcome 😊
Excellent!!
Literally a life saver study tool
please upload video on jumpers knee and how to treat its bump?
We will upload videos on different pahtologies more and more...Jumper's knee will certainly be one of them!
Thnk u, for informtion
You’re welcome 😊
What is the treatment show dt
Depends on the severity. In some cases a cast is necessary, usually strengthening and coordination exercises and gradual bulid up based on pain.
Tnk u sir 💓
excellent! thank you
Ur welcome Lorenzo! Thanks for following us!
Does any knowledgeable person have any information about new medical technology to repair torn pcl knee ligaments and osteoarthritis. I have heard there are new and exciting things being done with stem cells, spider silk, and new 3D cat scans.
What is the purpose of performing external rotation first?
Valgus is your knee got internal rotated'd so do the opposite
thank uuuu
how many mm should be the gapping and the normal?
Why do you assess in full extension and 20-30 degrees of flexion?
Full extension mainly tests the structure of the posteromedial complex (PMC), while 20-30° of flexion+valgus puts more direct stress on the MCL
Ok so my ligament on the outside part of my knee hurts, how can I de stress it??
For any personal health or rehab questions we recommend to consult with our partners at yourphysio.online for a remote physiotherapy consultation.
What is the different between Abduction & Hughston's valgus stress test, please ?
The Valgus stress test is usually done in 30° of flexion for the anteromedial part of the capsule and the superficial MCL and in extension for the posteromedial corner which is basically the same as abduction.
Je demande numéro je demande numéro
what was meant by excessive gapping on the medial side?
Increased laxity/mushy end feel when testing passive abduction at end range
good
Why should there be an exorotation when performing the valgus and varus stress-test?
We are tought to do it without a rotation. As the Lig. collaterale laterale + mediale run more or less vertical, I can not see any reason to rotate the tibia. At least no reason to specifically exorotate...
Hi Robin. The collaterals don't run vertical. The MCL runs from dorsal on the femur to ventral on the tibia and the LCL runs from ventral on the femur to dorsal on the tibia - same reason why both ligaments limit external rotation of the tibia.
Therefore, externally rotation the tibia puts more tension/stress on the collateral ligaments.
What does he mean by “excessive gapping”?
Separation of the joint space on the medial side
You did valgus in right leg only and varus in left only, I was looking each for opposite side as well
They are the same. You just place the left hand where the right hand was and vice-versa
Physiotutors i know this. But to perform in exam, i wanted to see how to switch hands and i dont find it smooth. Please post link of any video that shows it, valgus on both sides of each leg and varus too
I’m here for my sports medicine class
You aren’t palpating the MCL how!!
No, it's not palpating the MCL but assessing the gapping you feel (+pain provocation in more acute situations) through forcing the knee into a valgus position
