46-year-old man with right knee pain. MENISCI: The lateral meniscus appears normal. There is increased signal intensity within the root of the posterior horn of the medial meniscus, which may reflect focal degeneration. There is also focal signal abnormality in the underlying tibia. ARTICULAR CARTILAGE AND BONE: There is mild focal degeneration of the articular cartilage of the patella at the median eminence. The remaining articular cartilage of the knee appears normal. The remaining bone marrow signal intensity is within normal limits.LIGAMENTS: The ACL and PCL appear intact. The MCL and LCL complex appear intact. There is mild edema between the iliotibial band and lateral femoral condyle. There is additional mild edema within the subcutaneous fat along the anterolateral aspect of the tibia.EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact. There is mild edema in the subcutaneous fat anterior to the patella and patellar tendon, which is nonspecific. ADDITIONAL
1.Normal appearance of the lateral meniscus.2.Increased signal intensity within the root of the posterior horn of the medial meniscus suggesting degeneration.3.Mild subcutaneous edema as described above. Mild edema deep to the iliotibial band could reflect a "friction syndrome."4.Other findings as above.
