Reason: L knee pain, swelling, giving out x 8-9 months History: L knee pain, swelling, giving out x 8-9 months Please note that the high-resolution coil was unable to be used secondary to patient body habitus. An alternative coil was used, however, image quality is suboptimal.MENISCI: There is globular high signal intensity in the body of the medial meniscus extending into the posterior horn without a clear linear component. The lateral meniscus appears intact. ARTICULAR CARTILAGE AND BONE: There is marked thinning with full-thickness signal abnormalities of the articular cartilage of the patella, particularly along its medial facet. There is also pronounced thinning of the condylar surface of the medial compartment. Patchy red marrow signal is seen within the distal femur and proximal tibia. The bones are otherwise unremarkable.LIGAMENTS: Edema-type signal intensity surrounding the medial collateral ligament and iliotibial band suggest a low grade sprain. There are no full thickness defects identified. The cruciate ligaments are intact.EXTENSOR MECHANISM: There is edema throughout the subcutaneous tissues of the knee, particularly within the fat anterior to the patella and proximal tibia. The quadriceps and patellar tendons appear intact.ADDITIONAL
1. Degeneration of the medial meniscus without a definite tear.2. Sprain of the medial collateral ligament and iliotibial band.3. Degeneration of the articular cartilage of the patella and medial tibiofemoral compartment.
