Knee pain MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is an area of focal full-thickness cartilage defect involving the femoral trochlea centrally with degenerative cystic changes underlying the defect. Heterogeneous signal within the patellar cartilage likely reflects degenerative change and may be a small partial-thickness defect of the medial femoral condyle. The articular cartilage of the lateral and patellofemoral compartments is intact.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Full-thickness cartilage defect of the femoral trochlea centrally with additional degenerative changes noted in the patellofemoral articulation. The remaining articular cartilage of the medial lateral compartments is intact.2. Small joint effusion.
