Left knee pain The examination is limited by patient motion artifact.MENISCI: There is abnormal signal intensity throughout most of the medial meniscus representing extensive degeneration and degenerative tearing. There is mild medial extrusion of the body of the medial meniscus. There is intrasubstance degeneration of the lateral meniscus which is otherwise intact.ARTICULAR CARTILAGE AND BONE: There is severe degeneration of the articular cartilage of the medial compartment with large areas along both the tibial plateau and femoral condyle devoid of articular cartilage. Degenerative cysts and edema type signal are identified within the medial compartment as well. There is moderate osteoarthritis affecting the patellofemoral joint with partial and full-thickness defects of the articular cartilage. Associated degenerative edema type signal and degenerative cysts are noted particularly along the lateral patellar facet.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Severe osteoarthritis of the knee particularly affecting the medial tibiofemoral compartment with extensive degeneration and degenerative tearing of the medial meniscus.2. Moderate joint effusion.3. Tapering of the popliteal vein posterior to the knee joint with portions of the vessel not visualized. The possibility of a chronic thrombosis cannot be excluded and this can be further evaluated with Doppler sonography as clinically warranted.
