Intra-articular entrapment of the medial collateral ligament: radiographic and MRI findings
1Department of Radiology, Baystate Medical Center, 759 Chestnut Street, Springfield, MA 01199, USA.
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.
