53-year-old female with knee pain, evaluate meniscus MENISCI: There is oblique tear of posterior horn of the medial meniscus with extension to the femoral and tibial articular surfaces. There is globular signal abnormality within the body of the lateral meniscus without extension to either articular surface.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage loss along the medial patella undersurface with full-thickness degeneration and fissuring along the median eminence. Full-thickness and near full-thickness articular degeneration along the femoral trochlea with underlying reactive marrow changes. There is near full thickness loss of the articular cartilage along the medial femoral condyle with scattered foci of full-thickness degeneration and underlying reactive changes in the subchondral marrow. Mild diffuse articular cartilage thinning within the lateral tibiofemoral compartment.Tricompartmental osteophytes are noted.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: The quadriceps and patella tendons appear normal. There is marked prepatellar tendon soft tissue edema.ADDITIONAL
1. Severe osteoarthritis with tricompartmental articular cartilage loss as described above.2. Nondisplaced tear of the posterior horn of the medial meniscus as detailed above.3. Diffuse soft tissue swelling and fluid collection along the medial soft tissues which may reflect prior trauma/degloving injury.4. Moderate joint effusion and small Baker's cyst.
