The medial collateral ligament of the knee 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. It is also known as the tibial collateral ligament, or abbreviated as the MCL.
Causes of InjuryEdit
An MCL injury can be very painful and is caused by a valgus stress to a slightly bent knee, often when landing, bending or on high impact. Depending on the grade of the injury, the lowest grade (grade 1) can take between 2 and 10 weeks for the injury to fully heal. Recovery times for grades 2 and 3 are difficult to predict because of the amount of damage done can take weeks to several months. It is difficult to apply pressure on the injured leg for at least a few days.
