79-year-old female with knee pain. MENISCI: There is deformity and truncation of the inner fibers of the posterior horn of the lateral meniscus extending into the body and possibly the anterior horn, consistent with a complex, likely degenerative meniscal tear. There is fraying of the undersurface fibers of the posterior horn of the medial meniscus.ARTICULAR CARTILAGE AND BONE: There is significant thinning of the articular cartilage of the posterior weightbearing surface of the lateral femoral condyle. There is also mild thinning of the articular cartilage of the lateral patellar facet. No full-thickness cartilaginous defects are seen.LIGAMENTS: The anterior collateral and posterior collateral ligaments are intact. The lateral collateral and medial collateral ligaments are intact as well. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Complex, likely degenerative tearing of the lateral meniscus as detailed above.2.Thinning of the articular cartilage of the posterior weightbearing surface of the lateral tibiofemoral compartment as well as mild thinning of the articular cartilage of the lateral patellar facet.3.Tricompartmental osteophytosis consistent with mild osteoarthritis.
