Reason: knee pain History: pain MENISCI: There is increased signal within the lateral meniscus indicating intrasubstance degeneration. Horizontally oriented signal within the lateral meniscus extends to both the femoral and tibial articular surfaces suggesting degenerative horizontal tears. There is also thinning of the free edge of the posterior horn of the lateral meniscus likely representing additional chronic attritional tearing. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: Residual red marrow within the distal femur, proximal tibia and fibular head may reflect changes secondary to the patient's anemia. Small cysts are seen posteriorly within the intercondylar eminence of the tibia.LIGAMENTS: There is a tiny focus of cartilage degeneration along the posterior aspect of the medial femoral condyle but we see no fluid-filled defects. There is also mild degeneration of the articular cartilage of the lateral tibial plateau with mild degenerative signal abnormality in the underlying subchondral bone. EXTENSOR MECHANISM: There is edema within the subcutaneous fat anterior to the patella and proximal tibia.ADDITIONAL
1. Degeneration and degenerative tearing of the lateral meniscus.2. Mild osteoarthritis.3. Nonspecific soft tissue edema anteriorly and other findings as above.
