Female, 56 years old. Severe pain and swelling. Sjogren's. MENISCI: There is partial extrusion of the body of the medial meniscus with globular internal signal abnormality which is not definitely extend to an articular surface. There is apical blunting/finding loss of the anterior horn of the lateral meniscus. ARTICULAR CARTILAGE AND BONE: There is mild diffuse cartilage thinning of the patella, with a focal full-thickness defect along the lateral patellar facet with mild underlying marrow signal abnormality as well as a partial-thickness defect near the apex. There is a large area of full thickness cartilage loss involving the medial femoral condyle and medial tibial plateau with bone marrow reactive changes predominantly affecting the femoral condyle and to a lesser degree the tibial plateau. The lateral tibiofemoral articulation shows mild to moderate diffuse cartilage thinning without focal defect or underlying marrow signal abnormality.LIGAMENTS: Cruciate and collateral ligaments are intact.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1.Full-thickness cartilage loss involving the medial tibiofemoral articulation with bone marrow reactive changes predominantly affecting the medial femoral condyle. Associated partial extrusion of the body of the medial meniscus without definite tear.2.Focal patellar full-thickness cartilage defects and associated marrow reactive changes as above.3.Moderate joint effusion.
