Male, 61 years old. Left knee pain MENISCI: There is mild globular intrasubstance degeneration affecting the meniscus, but we see no tear.ARTICULAR CARTILAGE AND BONE: There is heterogeneity of the articular cartilage of the patella indicating mild to moderate degeneration with partial- and full-thickness foci of cartilage loss. Mild heterogeneity of the articular cartilage of the femoral trochlea likely represents minimal degeneration. There is also mild degeneration of the articular cartilage along the lateral femoral condyle anterior to the meniscus. There is a lobulated lesion within the distal femoral metaphysis, representing a benign enchondroma.LIGAMENTS: There is increased intrasubstance signal within the proximal half of the posterior cruciate ligament, likely representing chronic mucoid degeneration or less likely a partial thickness tear. The proximal fibers of the medial collateral ligament appear slightly thickened, which may reflect old injury, but we see no edema to reflect acute injury. The lateral collateral ligament complex is intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Cartilage degeneration as described above, particularly affecting the patella.2.Mucoid degeneration of the posterior collateral ligament and other findings as described above, but no meniscal tear is noted.
