Female 52 years old Reason: meniscal tear History: knee pain. MENISCI: There is mild intrasubstance signal within the medial meniscus suggesting mild mucoid degeneration. There is also attenuation of the body of the medial meniscus that may reflect chronic attritional fraying, but we see no discrete meniscal tear. The lateral meniscus is unremarkable.ARTICULAR CARTILAGE AND BONE: There is moderate osteoarthritis of the patellofemoral joint with full-thickness cartilage loss along the medial facet of the patella. There are also subchondral cysts in the patella and additional cartilage defects in the femoral trochlea. There is a full thickness, or near full thickness, defect of the articular cartilage of the medial femoral condyle just above the free edge of the posterior horn of the medial meniscus that measures just under 1 cm in diameter. Articular cartilage of the lateral compartment appears intact.LIGAMENTS: Cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: Extensor mechanism is intact.ADDITIONAL
1.Findings suggestive of chronic attritional fraying of the medial meniscus, but no discrete meniscal tear.2.Osteoarthritis as described above.3.Joint effusion with cartilaginous loose body as described above.
