59-year-old female with right knee pain stepping into a hole. Evaluate for medial meniscal tear. MENISCI: There is a radial tear of the posterior horn of the medial meniscus, near its root. There is also a horizontal tear of the posterior horn of the medial meniscus which extends to the body of the meniscus. The anterior horn appears intact. There is globular signal abnormality posterior horn of the lateral meniscus indicating intrasubstance degeneration. Some of the signal extends to the tibial articular surface consistent with degenerative tearing/fraying, appearing similar to the prior study.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the lateral facet of the patella with underlying degenerative subchondral signal abnormality. There is full-thickness articular cartilage degeneration within the medial facet of the patella with portions completely devoid of articular cartilage. There is near full-thickness to full-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle above the body and posterior horn of the meniscus. There is also full-thickness articular cartilage degeneration along the medial aspect of the tibial plateau.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, new from prior examination. 2. Intrasubstance degeneration/tearing of the lateral meniscus appearing similar to the prior study. 3. Small joint effusion and articular cartilage degeneration as described above. Other findings as described above.
