Knee pain The examination is slightly limited secondary to motion artifact.MENISCI: There is abnormal signal intensity and morphology of the posterior horn and body of the medial meniscus (particularly of the undersurface) consistent with complex tearing.The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is mild thinning of the articular cartilage of the medial compartment but there is no full-thickness defect of either the medial or lateral compartment. There is fibrillation and irregularity of the articular cartilage of the patellar facet, particularly medially where there is a partial-thickness cleft identified. The articular cartilage of the femoral trochlea is intact. LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Complex tear of the medial meniscus.2. Mild to moderate articular cartilage loss of the patellar facet.3. Moderate joint effusion.
