Reason: Assess for meniscal tear History: Effusion, pain, + lateral mcmurray test. MENISCI: The medial and lateral menisci are intact without discrete tears.ARTICULAR CARTILAGE AND BONE: The articular cartilage is intact with no discrete focal defects.Bone marrow edema and subacute impaction fracture involving the posterior aspect of the medial tibial plateau. Small amount of bone marrow edema involving the proximal fibula. LIGAMENTS: The ACL is poorly visualized, wavy, and cannot be followed entirely to its insertion on the femur compatible with a partial thickness of full thickness tear. Small amount of pericruciate edema. The PCL and collateral ligaments are intact. EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
1.Subacute impaction fracture involving the posterior aspect of the medial tibia plateau. Small amount of bone marrow edema with the proximal fibula as well.2.Chronic partial thickness or full thickness tear of the proximal insertion of the ACL.3.Intact menisci.
