72-year-old female with left knee pain. Rule out meniscal injury. MENISCI: There is increased signal intensity within the inner third of the posterior horn of the medial meniscus indicating a radial tear with fluid signal intensity entering the undersurface of the posterior horn of the medial meniscus within the white zone indicating additional undersurface tearing. Overall the tears are seen on 4 consecutive sagittal images,. There is globular signal intensity which extends into the body of the medial meniscus indicating intrasubstance degeneration. The anterior horn appears intact. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is increased signal intensity and mild thinning of the articular cartilage of the medial facet of the patella indicating mild degeneration, considering the patient's age. There is linear increased signal intensity within the deep fibers of the articular cartilage of the medial facet of the patella which may represent focal delamination. There is also mild degeneration of the articular cartilage of the medial femoral condyle above and anterior to the posterior horn of the medial meniscus. The lateral compartment articular cartilage appears normal for age. There are small patellar osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Medial meniscus tear involving the inner fibers as described above.2. Mild cartilage degeneration.3. Small lobulated collection of fluid along the posteromedial aspect of the knee that may reflect a small ganglion or fluid within the semimembranosus tibial collateral ligament bursa.
