Male, 33 years old. Left knee pain. Concern for ACL injury. MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: There is bone marrow edema within the posterolateral tibial plateau and the fibular head which may be secondary to contusion. There is a bone fragment adjacent to the lateral aspect of the tibial plateau which likely represents a Segond fracture as seen on prior radiograph. The articular cartilage appears intact.LIGAMENTS: There is intermediate signal within the anterior cruciate ligament, however, some of the fibers appear intact which may indicate a partial tear. The posterior cruciate ligament appears intact. There is intermediate signal within the medial collateral ligament which may represent a sprain. The lateral collateral ligament appears intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Findings consistent with a partial tear of the anterior cruciate ligament and sprain of the medial collateral ligament.
