66-year-old female with right medial knee pain and swelling for 3 months. MENISCI: Note is made of blunting and linear increased signal abnormality which extends to the femoral articular surface of the posterior horn of the medial meniscus consistent with a complex tear, which extends to the body of the meniscus. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is thinning of the articular cartilage of the medial compartment. There is focal near full-thickness articular cartilage degeneration along the posterior aspect of the weightbearing portion of the medial femoral condyle above the posterior horn of the meniscus with underlying subchondral signal abnormality, likely degenerative in etiology. There is a partial-thickness articular cartilage fissure along the lateral facet of the patella. There is near full-thickness to full-thickness focal articular cartilage degeneration affecting the patellar cartilage, centrally, with underlying subchondral signal abnormality, likely degenerative in etiology.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the medial meniscus as described above.2. Small knee joint effusion.3. Articular cartilage degeneration and fissuring as described above.
