49-year-old male patient with pain after pedestrian versus car. Question of chondral injury. MENISCI: The lateral meniscus is intact. Internal signal within the posterior horn of the medial meniscus does not reach an articular surface and no discrete medial meniscal tear is identified. ARTICULAR CARTILAGE AND BONE: There is marked thinning of the articular cartilage of the anterior medial femoral condyle with generalized thinning anteriorly, though full thickness defect. There is generalized thinning of the weightbearing portion of the lateral femoral condyle articular cartilage. There is fissuring of the medial facet patellar articular cartilage with minimal subchondral edema within the bone. Bone marrow signal is otherwise within normal limits. LIGAMENTS: The anterior and posterior cruciate ligaments are intact. The collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Chondromalacia without full thickness defect.2. Intact meniscal and ligamentous structures.
