The medial collateral ligament (MCL) is a broad, thick band that runs down the inner part of the knee, from the femur (thighbone) to about four to six inches from the top of the tibia (shinbone).The MCL's primary function is to prevent the leg from over-extending inward, but it also is part of the mechanism that stabilizes the knee and allows it to ...
The MCL is another one of the four ligaments in the knee. The MCL is on the inside of the knee joint. and spans the distance from the end of the femur (thigh bone) to the top of the tibia (shin bone). The MCL resists widening of the inside of the joint, or prevents opening-up of the knee. The MCL is usually injured when the outside of the knee joint is struck, causing the outside of the knee to buckle, and the inside to widen. When the MCL is stretched too far, it may tear. A MCL injury may be an isolated injury, or it may be part of a complex injury to the knee. Other ligaments, most commonly the ACL or the meniscus may be torn along with a MCL injury. MCL injury pain is usually focused directly over the ligament.
