50 year-old female with pain, evaluate for patella chondromalacia MENISCI: The medial and lateral menisci are intact.ARTICULAR CARTILAGE AND BONE: The medial facet of the trochlea and trochlear groove appear flattened, consistent with dysplasia. Heterogeneity of the cartilage along the medial and lateral undersurface patella indicating partial thickness degeneration. There is a small associated focal full thickness cartilage defect along the posteromedial tibial plateau with underlying cyst formation. Addiontal increased T2 signal is present in the lateral tibial plateau and intercondylar notch. LIGAMENTS: The cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: The patella tendon and quadriceps tendon are intact.ADDITIONAL
1. Findings consistent with trochlear dysplasia partial-thickness patellofemoral chondromalacia.2. Small, focal full-thickness articular cartilage defect in the posteromedial tibial plateau with underlying cyst formation.3. Intact cruciate and collateral ligaments.
