Knee pain MENISCI: Abnormal linear signal within and attenuation of the posterior horn of the medial meniscus, compatible with a horizontal cleavage tear. No significant abnormality noted in the lateral meniscus.ARTICULAR CARTILAGE AND BONE: Tricompartmental joint space narrowing with small osteophytes. Diffuse marked cartilage loss in all three compartments of the knee, with areas of partial thickness cartilage defects at the bilateral femoral condyles and full thickness loss at the lateral facet of the patella. Bone marrow signal is within normal limits. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
