53-year-old male with right medial joint line tenderness, evaluate for meniscal tear MENISCI: There is attenuation of the body and posterior horn of the medial meniscus, likely representing diffuse chronic attritional tearing in the absence of a history of partial meniscectomy. Additionally, there is a more focal defect along the undersurface of the body of the meniscus that is contiguous with abnormal signal within the meniscal substance suggesting a combination of degeneration and undersurface tearing. We see no displaced meniscal fragment. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: Subjectively, there is thinning of the articular cartilage within the medial tibiofemoral joint compartment with no fluid-filled defect visualized. Edema type signal within the medial aspect of the medial tibial plateau is noted beneath the torn meniscus. A small focal defect of the articular cartilage along the lateral tibial plateau near the lateral tibial spine is noted with mild associated signal abnormality within the underlying bone. There is focal signal heterogeneity within the central trochlea consistent with full-thickness degeneration with cyst formation within the underlying bone. Mild heterogeneity of the cartilage along the medial facet of the patella likely represents mild degeneration. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Globular increased signal intensity within the lateral distal quadriceps tendon, as well centrally more proximally within tendon indicates mild tendinosis. The patella tendon is intact.ADDITIONAL
