Reason: ACL recon assessment. History: right knee pain Evaluation of the knee is slightly limited by metallic susceptibility artifact related to the patient's ACL reconstruction.MENISCI: A small amount of intrasubstance signal is seen within the posterior horn of the medial meniscus, but no discrete tear is identified. The lateral meniscus is intact.ARTICULAR CARTILAGE AND BONE: We see no fluid-filled articular cartilage defects. There is mild edema of the lateral tibial plateau posteriorly.LIGAMENTS: The patient has undergone ACL reconstruction with expected surgical changes in the distal femur and proximal tibia. The graft appears intact. Low signal intensity anterior to the graft has the appearance of metal artifact rather than arthrofibrosis. The PCL and remaining ligaments are intact. EXTENSOR MECHANISM: No significant abnormality noted.ADDITIONAL
1. Surgical changes of ACL reconstruction. The graft appears intact.2. Focal edema in the posterior aspect of the lateral tibial plateau may reflect a bone contusion.
