Anatomy of the MCL

The medial collateral ligament is a band of fibrous tissue supporting the medial (inner) aspect of the knee joint. It has both a superficial and a deep component, which are separated by a 'pocket' called a bursa. The superficial component has a connection to the posterior (rear) part of the outer rim of the medial meniscus, while the deep component is even more intimately associated with the central part.

The medial and lateral ligament form part of the capsular structures of the knee. They are not visible from within the knee cavity.

Most MCL injuries will heal if the joint is properly protected during rehabilitation.
