Reason: r/o ligamentous tear History: persistent pain and swelling after fall two months ago MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness degeneration of the articular cartilage of the patella, centrally, with possible full-thickness fissuring/delamination. There is subchondral signal abnormality in the underlying bone which is likely degenerative. There is relative sparing of the medial and lateral compartment articular cartilage.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact. There is increased signal intensity between the prepatellar fibers of the rectus femoris and the underlying patella that may represent mild stripping. ADDITIONAL
1. Heterogeneous collection within the subcutaneous fat anterior to the patella likely representing a hematoma or perhaps a chronic bursitis with additional subcutaneous edema extending along the patellar tendon into the anterior soft tissues of the leg.2. Degeneration of the articular cartilage of the patella and other findings as described above.
