Male, 27 years old. Twisted knee while playing soccer, has history of partial ACL tear in the past that was not operated upon. MENISCI: The menisci appear intact.ARTICULAR CARTILAGE AND BONE: There is edema within the medial and lateral tibial plateaus posteriorly indicating bone contusions. There is also subchondral edema within the lateral femoral condyle above the anterior horn of the lateral meniscus with slight depression of the articular surface indicating a mild impaction fracture. A low signal intensity focus within the articular cartilage of the lateral articular facet of the patella may reflect focal degeneration or tearing. The femoral trochlea appears shallow, suggesting femoral trochlear dysplasia. We see no fluid-filled articular cartilage defects.LIGAMENTS: The anterior cruciate ligament is thickened and poorly defined indicating a full-thickness rupture, we suspect through its proximal to mid fibers. The PCL is intact. The medial collateral ligament and lateral collateral ligament complex are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Anterior cruciate ligament rupture and other findings as above.
