Reason: MCL Sprain? History: pain MENISCI: There is increased signal abnormality within the medial meniscus indicating intrasubstance degeneration. There is deformity and blunting of the posterior horn of the medial meniscus indicating a complex degenerative tearing. The anterior horn appears intact. There is increased signal within the lateral meniscus indicating intrasubstance degeneration. Some of this signal extends to the tibial articular surface indicating degenerative tearing. There is associated parameniscal cyst formation confirming a tear.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the medial aspect of the medial tibial plateau with underlying subchondral signal abnormality. There is partial-thickness articular cartilage degeneration with superficial fraying along the weightbearing surface of the medial femoral condyle. There is full-thickness articular cartilage degeneration along the medial facet of the patella with large areas completely devoid of articular cartilage. There is underlying subchondral signal abnormality. There is superficial fraying and partial-thickness degeneration of the articular cartilage along the medial facet of the femoral trochlea.LIGAMENTS: There is increased signal abnormality about the superficial band of the MCL indicating a mild sprain. The PCL appears intact. The ACL appears intact. The LCL appears intactEXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Mild sprain of the MCL.2. Degeneration and complex tearing of the medial meniscus. 3. Full-thickness articular cartilage degeneration most pronounced along the patellofemoral articulation.
