Knee pain MENISCI: There is attenuation of the posterior horn and body of the medial meniscus representing degenerative tearing. Additionally, there is abnormal signal intensity within the body and posterior horn which extends to the tibial articular surface representing more focal tearing. There is deformity of the posterior horn of the medial meniscus near the root likely representing additional tearing with a displaced flap fragment.There is globular increased signal throughout much of the lateral meniscus representing intrasubstance degeneration with linear signal intensity of the posterior horn extending to the femoral articular surface indicating more focal tearing. There is truncation of the root of the posterior horn of the lateral meniscus likely representing a large radial tear with associated lateral extrusion of the body of the lateral meniscus. Signal abnormality within the body of the lateral meniscus extending to the tibial articular surface represents additional tearing as does branching signal abnormality and fragmentation of the anterior horn.ARTICULAR CARTILAGE AND BONE: There is severe osteoarthritis of the lateral compartment with areas of full-thickness cartilage loss, subchondral cystic change, and subchondral edema along the weightbearing portions of both the lateral tibial plateau and lateral femoral condyle. There is relatively mild cartilage degeneration of the medial compartment. There are full-thickness clefts involving the articular cartilage of the patella along the median eminence and medial facet with additional superficial degeneration along the lateral facet. There is also a low signal intensity full-thickness cleft of the articular cartilage of the femoral trochlea centrally. There are tricompartmental osteophytes and osteoarthritis of the proximal tibiofibular articulation.LIGAMENTS: The cruciate and collateral ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Severe osteoarthritis of the knee, particularly of the lateral compartment, with extensive tearing of both the lateral and medial menisci. Additional findings are described above.
