16 year old female with a history of ACL reconstruction with injury one week prior, feels loose, evaluate for tear of the ACL reconstruction versus medial meniscus tear. MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: No articular cartilage defects are identified.LIGAMENTS: The patient is status post ACL reconstruction. The ACL graft is indistinct likely representing a tear. This is perhaps a chronic tear as there is minimal if any edema within the lateral tibial plateau and lateral femoral condyle. The PCL, MCL, and LCL appear intact. The distal gracilis and semitendinosus tendons are indistinct which may reflect harvesting for the ACL graft.EXTENSOR MECHANISM: The extensor mechanism appears intact.ADDITIONAL
Findings compatible with a tear of the patient's ACL reconstruction. No evidence of meniscal tear. Other findings as described above.
