65-year-old female with right knee pain and antalgic gait with history of osteoarthritis, evaluate for meniscus tear MENISCI: Globular increased signal intensity within the medial meniscus at the junction of the body and posterior horn represents intrasubstance degeneration. Additionally, the inner third of the posterior horn of the medial meniscus is replaced with intermediate signal intensity likely representing degenerative tearing. Horizontally oriented signal abnormality within the posterior horn of the medial meniscus may represent additional tearing. The anterior horn of the medial meniscus appears intact. Increased signal intensity within the undersurface fibers of the inner half of the posterior horn of the lateral meniscus likely represents a degenerative articular surface tear. Intermediate signal within the body and anterior horn of the lateral meniscus suggests degeneration.ARTICULAR CARTILAGE AND BONE: Severe osteoarthritis affects the patellofemoral joint with subchondral cysts along the lateral facet of the patella and the femoral trochlea. There is moderate thinning of the articular cartilage along the weightbearing portion of the medial femoral condyle. There is also subchondral cyst formation posteriorly within the medial femoral condyle. Edema-type signal within the lateral tibial plateau with heterogeneity of overlying articular cartilage is likely degenerative in etiology. Tricompartmental osteophytes are noted.LIGAMENTS: There is mild edema along the medial collateral ligament, but the ligament itself appears intact. The lateral collateral ligament proper appears attenuated which may reflect prior injury, but this is equivocal. The iliotibial band and biceps femoris tendon are intact.EXTENSOR MECHANISM: The extensor mechanism is intact.ADDITIONAL
Tricompartmental osteoarthritis with degenerative tearing of both menisci and other findings as described above.
