68 year old female with possible right patellar tendon tear on plain film. MENISCI: The medial meniscus appears intact. There is globular increased signal abnormality within the body of the lateral meniscus consistent with intrasubstance degeneration. Some of this signal extends to the femoral articular surface consistent with degenerative tearing/superficial fraying.ARTICULAR CARTILAGE AND BONE: There is a focal full thickness articular cartilage cleft along the medial facet of the patella with underlying degenerative subchondral signal abnormality and cyst formation. There is subjective thinning of the lateral tibiofemoral compartment articular cartilage. There is a focal full-thickness articular cartilage degeneration along the lateral tibial plateau with underlying subchondral signal abnormality. There is full-thickness articular cartilage degeneration along the posterior aspect of the medial femoral condyle with underlying degenerative subchondral signal abnormality.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact. There is increased signal abnormality within the distal fibers of the patellar tendon indicating mild patellar tendinosis.ADDITIONAL
1. Findings consistent with mild patellar tendinosis. The patellar tendon appears intact.2. Full-thickness articular cartilage cleft and degeneration as described above.3. Intrasubstance degeneration/degenerative tearing of the lateral meniscus.4. Nonspecific subcutaneous edema along the anterior aspect of the patellar tendon.
