Male, 48 years old. Reason: right knee medial meniscus tear History: knee pain MENISCI: There is a bucket-handle tear of the medial meniscus with displacement of the bucket-handle fragment along the medial tibial spine. Additional branching signal abnormality within the posterior horn of the medial meniscus is seen extending to the femoral and tibial articular surfaces representing complex tearing. Overall, the appearance is similar to that seen on the prior study. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: Subjectively the articular cartilage of the medial compartment appears thinned, particularly along the tibial plateau beneath the posterior horn of the meniscus and along the weightbearing surface of the medial femoral condyle. There is also a small full-thickness defect anteriorly along the medial femoral condyle. The articular cartilage of the lateral compartment appears relatively normal. There is a partial-thickness cleft of the articular cartilage of the medial articular surface of the patella and mild blistering of the articular cartilage of the lateral articular surface of the patella. Overall, these findings appear similar to those seen on the prior study. Bone marrow signal intensity is within normal limits.LIGAMENTS: The ligaments of the knee appear normal. EXTENSOR MECHANISM: The extensor mechanism is intact. There is scarring along the anterior capsular structures of the knee which presumably reflects prior surgery.ADDITIONAL
Bucket-handle tear of the medial meniscus and other findings as described above.
