Reason: pain, difficulty with ambulation History: pain MENISCI: The lateral meniscus appears intact. The medial meniscus appears intact.ARTICULAR CARTILAGE AND BONE: The medial and lateral compartment cartilage appears intact without evidence of a full-thickness or near full-thickness articular cartilage defects. There is superficial fraying and partial thickness fissuring of the articular cartilage along the lateral facet of the patella as well as along the median eminence of the patella.LIGAMENTS: The cruciate and collateral ligaments appear intact. There is increased signal abnormality within the proximal fibers of the lateral collateral ligament proper which may reflect a mild sprain. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Subcutaneously edema interposed between the iliotibial band and lateral femoral condyle may reflect a mild sprain injury. Alternatively, this could represent the sequela of iliotibial band friction syndrome, particularly if the patient is an avid runner.2. Superficial fraying and partial-thickness articular cartilage fissuring along the lateral facet of the patella with elevated tibial tubercle trochlear groove distance. These findings can be seen in patellofemoral instability.
