Known osteochondral defect MENISCI: The medial meniscus is unremarkable. The lateral meniscus however demonstrates fraying of the inner edge with more discrete loss involving the apical aspect involving the posterior horn. Specifically extension is observed to the inferior articular surface. Both menisci are well anchored posteriorlyARTICULAR CARTILAGE AND BONE: The large medial femoral condyle osteochondral defect is again observed measuring 2 cm in both AP dimension and medial laterally. Depth approximately 6 mm in the defect extends up to and just touching the intercondylar notch. No evidence of underlying loosening or abnormal fluid.Marrow signal is otherwise unremarkable. The remaining cartilage is otherwise also unremarkable without focal defectsLIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Large medial femoral condylar osteochondral defect and minimal apical lateral meniscal tear extending into the posterior horn.
