Pain. Fall injury to left knee. MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: There is a subtle decreased T1 and high T2 signal within the lateral aspect of the lateral femoral condyle with minimal depression of the cortical surface compatible with an impaction injury/bone contusion. Edema is also noted within the posterior aspects of the medial and lateral tibial plateaus.There is minimal thinning of the weight-bearing portion of the articular cartilage of the medial femoral condyle. There is slight thinning of the articular cartilage of the anterior lateral femoral condyle. The extensor compartment articular cartilage is intact.LIGAMENTS: There is a complete tear of the anterior cruciate ligament. The posterior cruciate ligament is intact. The collateral ligaments are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
