Reason: Assess L knee for cause of diffuse pain History: h/o L knee arthroscopy x 2 (4/2015 and 9/2015) for medial meniscal tear s/p partial medial meniscectomy x 2 and chondroplasty med fem condyle and patellofemoral joint x 2 MENISCI: There is blunting of the posterior horn and body of the medial meniscus likely representing a combination of degeneration, postsurgical change and prior tearing. There is linear increased signal abnormality within the body and posterior horn of the meniscus which extends to the femoral articular surface suspicious for a horizontal tear. The lateral meniscus appears intact.ARTICULAR CARTILAGE AND BONE: There is partial-thickness articular cartilage degeneration along the weightbearing surface of the medial femoral condyle. There is relative sparing of the lateral compartment articular cartilage. There is full-thickness chondromalacia along the medial facet of the patella.LIGAMENTS: There is thickening and increased signal abnormality within the anterior cruciate ligament. The PCL appears intact. The LCL and MCL appear intact. EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
1. Blunting of the posterior horn and body of the meniscus likely representing a combination of degeneration, postsurgical change and prior tearing. There is linear increased signal abnormality within the body and posterior horn of the meniscus which extends to the femoral articular surface suspicious for a re-tear. 2. Osteoarthritis of the knee with articular cartilage degeneration most pronounced along the medial femoral condyle.3. Small joint effusion.4. Findings indicating mucoid degeneration of the ACL, although this could represent a sprain injury in the correct clinical context.
