    The medial collateral ligament (MCL or tibial collateral ligament) is one of the four major ligaments of the knee. It is on the medial (inner) side of the knee joint in humans and other primates.

    Doctor Christopher Zarembinski:The lateral meniscus is less likely to be injured or torn than the medial meniscus. Diagnosis of lateral meniscus tear is done with McMurray's test. If a tear is detected, treatment depends on the type and size of the tear. Small tears can be treated conservatively, with rest, ice, and pain medications until the pain is under control, then exercise may be started with gradually increasing intensity, to improve range of motion and decrease swelling. More severe tears of the lateral meniscus require surgical repair or removal, which can often be done arthroscopically. Swelling and stiffness of the knee can occur when you have a torn lateral meniscus.

    Dr Christopher Zarembinski

    It is fused with the tibial collateral ligament which makes it far less mobile than the lateral meniscus. The points of attachment are relatively widely separated and, because the meniscus is wider posteriorly than anteriorly, the anterior crus is considerably thinner than the posterior crus. The greatest displacement of the meniscus is caused by external rotation, while internal rotation relaxes it.

    Dr Zarembinski:

    The anterior attachment of the lateral meniscus is twisted on itself so that its free margin looks backward and upward, its anterior end resting on a sloping shelf of bone on the front of the lateral process of the intercondyloid eminence.
    Doctor Christopher Zarembinski
    The lateral meniscus is grooved laterally for the tendon of the popliteus, which separates it from the fibular collateral ligament.
    Its anterior end is attached in front of the intercondyloid eminence of the tibia, lateral to, and behind, the anterior cruciate ligament, with which it blends; the posterior end is attached behind the intercondyloid eminence of the tibia and in front of the posterior end of the medial meniscus.
