22-year-old male with history of lateral knee pain status post ACL repair MENISCI: The medial and lateral menisci appear intact.ARTICULAR CARTILAGE AND BONE: Old mild deformity of an impaction fracture of the lateral femoral condyle is seen overlying the anterior horn of the lateral meniscus. The overlying articular cartilage appears intact. The remainder of the articular cartilage is within normal limits. There is mild edema type signal within the intracondylar eminence of the tibia, particularly within the medial tibial spine just posterior to the graft, which may be reactive in etiology.LIGAMENTS: The patient is status post ACL reconstruction with the graft appearing slightly thickened and mildly heterogeneous in signal intensity, but otherwise intact. There is focal increased signal intensity within the anterior fibers of the graft, which can be seen in graft impingement. A small focus of intermediate signal intensity immediately anterior to the graft may represent scar tissue, also seen on the prior exam. The PCL is intact. The medial and lateral collateral ligaments are intact.EXTENSOR MECHANISM: The quadriceps tendon is intact. The patella tendon is bisected and thickened, representing changes from prior graft harvesting, appearing similar to the prior exam.ADDITIONAL
Postoperative changes of ACL graft reconstruction appearing similar to the prior exam, with slight heterogeneity of the graft that could represent impingement in the appropriate clinical setting. We see no articular cartilage injury, meniscal tear or loose body.
