This is patient who is post ACL repair with persistent flexion deformity. MRI was done as a part of evaluation. MRI revealed following : Metallic screws are noted in the lower end of femur and tibia limiting the evaluation by resultant suspectibility artifacts. There is evidence of altered signal intensity around the ACL graft which is not well seen which probably indicates arthrofibrosis of the ACL graft. There is evidence of altered lesion in the tibial insertion of the graft which may be indicative of cyclops lesion versus cystic lesion as it hyperintense on T2 weighted images and cyclops lesion is usually low-intermediate signal. Tibial tunnel appears mildly anteriorly placed as compared to intercondylar roof line.
