Right knee pain MENISCI: There is abnormal signal throughout the majority of the posterior horn of the medial meniscus indicating complex tearing with an additional large radial component. The peripheral fibers of the posterior horn are present but also demonstrate abnormal signal suggesting degenerative tearing. Degeneration and tearing extends to the body of the meniscus which is attenuated and extruded medially. There is mild fraying/tearing of the the inner edge of the anterior horn of the medial meniscus.There is blunting of the posterior horn of the lateral meniscus indicating a radial tear. Additional more horizontally oriented signal abnormality extends through the meniscus also reflective of tearing. Additionally, there is intra-/parameniscal cyst formation within the anterior horn and body.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage loss along the lateral femoral condyle and lateral tibial plateau adjacent to the posterior horn of the meniscus. There is similar full-thickness loss of the articular cartilage involving the medial femoral condyle and medial tibial plateau also at the level of the posterior horn of the meniscus. There is moderate degeneration of the articular cartilage of the patellofemoral compartment, particularly the lateral facet of the femoral trochlea. There are tricompartmental osteophytes with foci of degenerative subchondral marrow signal within both femoral condyles.LIGAMENTS: The ACL is intact. There is abnormal thickening and increased signal of the PCL reflective of mucoid degeneration or prior tearing. The medial collateral ligament and lateral collateral ligament complexes are intact.EXTENSOR MECHANISM: The extensor mechanism is intact. A small ossicle is noted within the distal patellar tendon which is of doubtful clinical significance.ADDITIONAL
Tricompartmental osteoarthritis with complex tears of the medial and lateral menisci and other findings as detailed above.
