Knee pain MENISCI: There is abnormal increased linear signal intensity within the body of the lateral meniscus indicating tearing which extends from the tibial articular surface through the peripheral fibers. There is a small associated parameniscal cyst and lateral extrusion of the body of the meniscus. The tear also propagates into the anterior horn where it appears to contact the femoral articular surface. The medial meniscus is intact.ARTICULAR CARTILAGE AND BONE: There is near full-thickness to full-thickness degeneration of the articular cartilage of the lateral tibial plateau along the intercondylar eminence. There is also superficial degeneration of the articular cartilage of the adjacent lateral femoral condyle. The articular cartilage of the medial compartment is intact. There is mild heterogeneous signal of the articular cartilage of the medial patellar facet which may reflect mild focal degeneration. The articular cartilage of the lateral patellar facet and femoral trochlear is intact. Residual red marrow is noted within the distal femur, proximal tibia, and proximal fibula. LIGAMENTS: No significant abnormality noted. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Lateral meniscal tear as detailed above. The medial meniscus is intact.2. Cartilage loss of the lateral compartment with additional findings described above.
