55-year-old male with left knee swelling. Evaluate for left knee meniscal tear. MENISCI: There is blunting/deformity and increased signal abnormality of the posterior horn of the medial meniscus which extends into the body of the meniscus consistent with the patient's known history of a meniscal tear. There is blunting and increased signal abnormality of the posterior horn of the lateral meniscus which extends to the tibial articular surface, consistent with a re-tear of the meniscus. ARTICULAR CARTILAGE AND BONE: There is fraying of the articular cartilage of the femoral trochlea as well as along the medial and lateral facets of the patella. There is near full-thickness articular cartilage degeneration along the medial femoral condyle. There is a small amount of bone marrow signal abnormality in the underlying area, likely degenerative. There is mild articular cartilage degeneration along the lateral femoral condyle. LIGAMENTS: The cruciate and collateral ligaments appear intact EXTENSOR MECHANISM: The extensor mechanism appears intactADDITIONAL
1. Tearing of the medial and lateral meniscus as described above.2. Articular cartilage degeneration as described above.3. Knee joint effusion.
