Abstract
Displacement of the medial collateral ligament (MCL) into the medial knee joint is an extremely rare finding associated with MCL tears, and is easily diagnosed on magnetic resonance imaging. A case of intra-articular interposition of the MCL during a severe knee injury is presented. A radiolucent "fat stripe" sign and adjacent skin dimpling on radiographs may be relatively specific indicators of this injury.
