Female 53 years old Reason: Evaluate for ligament or meniscus injury History: L knee pain/injury with gait instability MENISCI: Blunting of the medial meniscus with a complex tear of the posterior horn, consisting of a horizontal cleavage tear with an associated vertical component. The anterior horn of the lateral meniscus is obscured by metallic artifact. Anterior to the joint, at the fat pad of Hoffa there is considerable metallic artifact which may be concealing arthrofibrosis or a Cyclops lesion.ARTICULAR CARTILAGE AND BONE: There is severe thinning of the patellofemoral cartilage particularly overlying the lateral facet. There is mild thinning of the cartilage in the medial and lateral joint compartments however no full-thickness defect is identified.LIGAMENTS: Evaluation of the ACL autograft is limited by metallic artifact. Within this limitation the autograft appears to be impinging on the roof of the intercondylar notch with at least a partial ACL tear. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
