Reason: r/o torn patella tendon History: pain superior to patella with weight bearing MENISCI: Globular increased signal abnormality within the posterior horn of the medial meniscus indicating intrasubstance degeneration. Some of this signal extends to the femoral articular surface indicating superficial fraying. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: No bone marrow signal abnormality is identified. The medial and lateral compartment articular cartilage appears intact. There is a full-thickness articular cartilage cleft along the medial facet of the femoral trochlea with underlying subchondral signal abnormality and full-thickness articular cartilage degeneration in the surrounding area.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. A skin marker is noted along the superomedial aspect of the patella/quadriceps tendon presumably corresponding to the patient's area of concern. The quadriceps tendon is unremarkable. The patellar tendon appears intact. The vastus medialis muscle underlying the skin marker is unremarkable. There is nonspecific edema within the quadriceps fat pad which can be seen in fat pad impingement or contusion.ADDITIONAL
1. Full-thickness articular cartilage cleft along the medial facet of the femoral trochlea.2. Findings consistent with a ruptured Baker's cyst.3. Edema within the quadriceps fat pad is nonspecific but can be seen in fat pad impingement syndrome or contusion in the setting of trauma. Other findings as described above.
