69-year-old male with right pain. MENISCI: There is heterogeneity and increased signal abnormality within the posterior horn of the medial meniscus which extends to the tibial and femoral articular surfaces consistent with complex degenerative tearing that extends to the body and anterior horn of the meniscus. There is globular increased signal abnormality within the posterior horn indicating intrasubstance degeneration. There is globular increased signal abnormality within the posterior horn of the lateral meniscus indicating intrasubstance degeneration. Some of the signal extends to the tibial articular surface consistent with degenerative tearing. The anterior horn appears intact.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle above the posterior horn of the meniscus. There is near full-thickness to full-thickness articular cartilage degeneration along the medial tibial plateau with underlying degenerative subchondral signal abnormality There is superficial fraying of the articular cartilage along the medial facet of the patella. There are tricompartmental osteophytes. There is subchondral cyst formation within the anterior tibial plateau.LIGAMENTS: The cruciate ligaments appear intact. The LCL appears intact. The superficial band of the MCL appears intact. The meniscal femoral coronary ligament appears thickened which may reflect prior injury or sprain. There is a small amount of edema type signal abnormality along the medial aspect of the MCL which may reflect a sprain.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Tearing of the medial and lateral meniscus as described above.2. Osteoarthritis of the right knee with full-thickness articular cartilage degeneration as described above.3. Small joint effusion.4. Findings consistent with a MCL sprain.
