22-year-old male. Evaluate for meniscus tear. MENISCI: Again seen is branching signal abnormality in the posterior horn and body of the lateral meniscus that contacts the femoral and tibial surfaces as well as blunting of the free edge and body of the posterior horn, consistent with a complex tear. The medial meniscus is intact without evidence of a tear.ARTICULAR CARTILAGE AND BONE: There is increased marked thinning of the articular cartilage of the lateral femoral condyle just above the posterior horn of the lateral meniscus, with areas of near full-thickness cartilage loss. The patellofemoral compartment articular cartilage shows high signal abnormality and surface fraying with areas of partial thickness cartilage loss.Bone marrow signal intensity is within normal limits. There has been interval development of tricompartmental osteophytes.LIGAMENTS: The ACL graft is completely disrupted consistent with a full thickness tear. PCL, MCL, and LCL are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Findings consistent with an ACL graft full thickness tear.2. 11 mm loose body just above the tibial intercondylar eminence.3. Interval progression of chondromalacia of the lateral femoral condyle with areas of near full thickness cartilage loss and new chondromalacia of the patellofemoral compartment.4. Complex tear of the lateral meniscus, not significantly changed.
