Left knee pain MENISCI: There is marked attenuation of the anterior horn and body of the lateral meniscus compatible with chronic attrition and degenerative tearing (in the absence of prior meniscectomy). There is linear intrasubstance signal within the posterior horn which extends to the tibial articular surface, indicating additional tearing. This is superimposed upon mild attenuation of the posterior horn.There is globular intrasubstance degeneration of the body and posterior horn of the medial meniscus with additional vertically oriented intermediate signal within the posterior horn. This intermediate signal extends to both the femoral and tibial articular surfaces, indicating a vertical tear. There is a small parameniscal cyst adjacent to the posterior horn and body and there is blunting of the inner free edge of the posterior horn and body which indicates fraying. The anterior horn is intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness articular cartilage degeneration of the lateral femoral condyle and lateral tibial plateau with numerous intra-articular osteophytes present. There is thinning of the articular cartilage of the posterior aspect of the medial femoral condyle with numerous intra-articular osteophytes present in the medial compartment as well. Multiple focal full-thickness defects affect the patellofemoral joint with subchondral cystic changes in the underlying patella. A small cyst is noted within the lateral femoral condyle just posterior to the origin of the popliteal tendon.LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
Medial and lateral meniscal tears with tricompartmental osteoarthritis. Additional findings are detailed above.
