21-year-old male with lateral knee pain and catching MENISCI: The lateral meniscus is intact. There is mild signal heterogeneity within the peripheral fibers of the medial meniscus at the junction of the body and posterior horn extending to the femoral articular surface. This may represent a tear in the vascularized periphery of the meniscus but may be chronic and not necessarily of any current clinical significance.ARTICULAR CARTILAGE AND BONE: There is mild edema type signal within the posterior medial tibial plateau. The overlying articular cartilage is intact. The remainder of the tibiofemoral and patellofemoral articular cartilage is also intact.LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The quadriceps and patella tendons are intact.ADDITIONAL
1. No evidence of lateral meniscus tear. Mild heterogeneous signal intensity within the peripheral fibers of the medial meniscus could represent a tear in the red zone and may be chronic in etiology and not necessarily of any current clinical significance.2. Mild edema within the posterior medial tibial plateau, which is nonspecific but may represent a contusion.3. Baker's cyst.4. Mild nonspecific edema between the lateral gastrocnemius and popliteal tendons without disruption of the muscles or tendons.
