Medial collateral ligament injury
Resumo
Definição
The medial collateral ligament (MCL) is a supporting structure on the medial part of the knee joint. [Figure caption and citation for the preceding image starts]: Medial collateral ligament (right knee)Created by Sanjeev Bhatia, MD; used with permission [Citation ends].
Its primary function is to resist valgus (twisting outward away from the midline) and external rotation forces of the tibia in relation to the femur. The mechanism for MCL injury is typically a large valgus and/or external rotation force that is suddenly placed on the knee joint. Injuries to the MCL range in severity from a few torn fibers to complete disunity of the ligament.
