36-year-old male with positive Lachman's test MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: There is a lateral notch along the anterolateral femoral condyle with underlying articular cartilage defect measuring approximately 1 cm in AP dimension and extensive underlying edema consistent with contusion. Linear T1 hypointense signal associated with extensive edema in the posterolateral tibial condyle is consistent with fracturing and contusion, but there is no impaction. There is mild degeneration of the articular cartilage along the medial facet of the patella and posteromedial femoral condyle.LIGAMENTS: The ACL is completely torn. The PCL is intact. The medial and lateral collateral ligaments are intact.EXTENSOR MECHANISM: The patella and quadriceps tendon are intact.ADDITIONAL
1. ACL tear with associated contusions as described above.2. Chondral injury along the lateral femoral condyle. 3. Moderate joint effusion.
