Reason: Left knee chondromalacia History: Left knee pain MENISCI: The lateral meniscus appears intact. The medial meniscus appears intact. There is increased signal abnormality within the posterior horn of the medial meniscus indicating very mild intrasubstance degeneration. Some of the signal extends to the femoral articular surface indicating superficial fraying.ARTICULAR CARTILAGE AND BONE: There is a partial-thickness articular cartilage fissure along the medial facet of the patella, inferiorly. There is focal partial-thickness articular cartilage defect along the far medial aspect of the medial facet of the femoral trochlea with a small amount of underlying subchondral signal abnormality. There are small tricompartment osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: There is thickening of the patellar tendon with intermediate signal intensity indicating mild to moderate patellar tendinosis. There is a large enthesophyte along the superior aspect of the tibial tubercle at the level of the insertion of the patellar tendon which may represent the sequela of prior Osgood Schlatter's disease.ADDITIONAL
1. Focal partial-thickness cartilage defect and fissuring affecting the patellofemoral articulation.2. Findings indicating mild to moderate patellar tendinosis.3. Possible mild strain injury of the gastrocnemius as described above.
