Reason: fell on left knee History: has difficulty walking and swelling above the patella MENISCI: No significant abnormality noted.ARTICULAR CARTILAGE AND BONE: There is blistering and fraying of the articular cartilage of the medial patellar facet with edema-type signal in the underlying bone. Otherwise, the articular cartilage is unremarkable.LIGAMENTS: There is minimal edema along the superficial band of the MCL as well as the posterior oblique ligament which may represent sprain in the appropriate clinical context, but the medial collateral ligament is otherwise intact. The lateral collateral ligament is intact. EXTENSOR MECHANISM: The quadriceps and patellar tendons appear intact. There are enthesopathic changes affecting the anterior patella as seen on recent radiographs. There is edema in the soft tissues anterior to the patella as well as the patellar tendon, indicating inflammation, perhaps a bursitis. Furthermore, the fibers of the quadriceps continuation anterior to the patella appear focally disrupted, suggesting a partial tear.ADDITIONAL
1.Edema anterior to the patella and the patellar tendon suggests inflammation, perhaps a mild bursitis. Furthermore, the fibers of the quadriceps continuation anterior to the patella appear focally disrupted, suggesting a partial-thickness tear.2.Degeneration of the articular cartilage along the medial patellar facet with edema in the underlying bone.3.Moderate to large joint effusion and other findings as above.
