Male 56 years old Reason: Right knee pain, medial and anterior evaluate for meniscus tear, chondral injury History: Right knee pain MENISCI: There is a thin longitudinal, vertically orientated tear through the peripheral fibers of the posterior horn of the medial meniscus near its root. This was not clearly evident on prior study. It is present on at least two consecutive sagittal images. There is intrasubstance degeneration within the body of the medial meniscus. There is also mucoid degeneration resulting in a globular collection of intermediate signal within the anterior horn of the medial meniscus at its root which is new from prior study.Also seen is maceration of the anterior horn of the lateral meniscus with degeneration and extrusion of the body of the lateral meniscus that appears similar to prior. There is a new complex tear consisting of a complete longitudinal component involving the posterior horn of the lateral meniscus seen on several consecutive sagittal images.ARTICULAR CARTILAGE AND BONE: There is full thickness cartilage loss along the lateral tibial plateau anteriorly with underlying subchondral type edema and cysts which appear similar to prior study. There is also full-thickness cartilage loss along the lateral femoral condyle which appears similar to prior study. There is near full thickness to full-thickness degeneration along the far medial rim of the medial femoral condyle, similar to prior study. There are also subchondral cysts in the anterior aspect of the medial tibial plateau with degeneration of the overlying cartilage which appears to have progressed slightly compared to prior study. Relatively mild degeneration affects the cartilage of the patellofemoral joint which is similar to prior study. Tricompartmental osteophytes are noted.LIGAMENTS: The anterior cruciate ligament, posterior cruciate ligament, medial collateral ligament and lateral collateral ligament appear unremarkable. There is thickening of the lateral capsular ligament, unchanged in appearance compared to prior study.EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Severe degenerative arthritic changes of the right knee with new tears of the posterior horn of the medial meniscus and posterior horn of the lateral meniscus and other findings as described above.
