Reason: Assess for meniscal pathology History: Lateral knee pain MENISCI: There is blunting and deformity of the posterior horn of the lateral meniscus likely representing complex degenerative tearing. There is extension of this tearing to involve the body of the meniscus. The anterior horn appears intact. There is increased signal abnormality within the posterior the medial meniscus which extends to the tibial articular surface which may represent superficial fraying.ARTICULAR CARTILAGE AND BONE: There is full-thickness articular cartilage degeneration along the weightbearing surface of the lateral femoral condyle and lateral tibial plateau with areas completely devoid of articular cartilage, posteriorly. There is relative sparing of the articular cartilage of the medial tibiofemoral compartment. There is superficial fraying of the articular cartilage along the lateral facet of the patella. There are near full-thickness to full-thickness articular cartilage clefts along the lateral facet and median eminence of the patella with associated delamination. There are tricompartmental osteophytes.LIGAMENTS: The cruciate and collateral ligaments appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Complex degenerative tearing of the lateral meniscus 2. Osteoarthritis of the knee most pronounced along the lateral tibiofemoral compartment with full-thickness articular cartilage defects.3. Near full-thickness to full-thickness articular cartilage clefts with delamination along the lateral facet of the patella.4. Large joint effusion. Other findings as described above.
