By focusing on cyclops lesions, a source of knee extension loss after ACL reconstruction, we aimed to expand the comparison between these two autograft options. One common complication of ACL reconstruction is a limited range of motion, especially obtaining a fully straight knee. It can block the knee range of movement, limiting the full extension of the knee, and can therefore cause quadriceps dysfunction. ACL Reconstruction - Hamstring Autograft. Srinivasan R, Wan J, Allen CR, Steinbach LS. Increased preoperative and postoperative inflammation reflected by swelling, effusion, and hyperthermia also plays an important role in the development of this complication.7,11 On MRI, fibrotic tissue encases the ACL graft and can extend anteriorly into the infrapatellar fat pad and suprapatellar bursa or posteriorly to the posterior joint capsule (Figure 8).7. These exercises allow muscle recruitment without increasing the intra-articular pressure associated with full knee extension. Basically the cartilage on the underside of my patella is a rumble strip.

Keep up to date with the science and best practice in managing sports injuries. What is your diagnosis? A 32 year-old male 3 years post-ACL reconstruction with anteromedial knee pain. MRI can assist in the evaluation of arthrofibrosis in patients with a normal radiographic appearance of the implant but with a limited range of motion.17, MR imaging findings of diffuse arthrofibrosis include widespread heterogeneous thickening of the synovium. Following because this matches all of my issues to a T. I'm also a year and a half out, though I had a quad graft, and had a second surgery for more meniscus issues, bone spurs and cartilage blistering issues.

Women have a higher risk, as the intracondylar notch is narrower. Various terms have been used to describe this pathology including infrapatellar contracture syndrome, synovial fibrosis of the infrapatellar fat pad, scarring of the anterior interval, and patella infera syndrome.12,15,16 Postoperative scarring normally appears as thin linear or spiculated regions of low signal on all sequences with small slightly thickened and more nodular portions found along the route of the arthroscopic portals and at the posterior margin of the fat pad (Figure 9).16 In contrast, symptomatic fibrosis results from more extensive fibrotic changes appearing as thickened and irregular areas of low signal on all sequences, which can greatly reduce the amount of normal fat. (2007). Unable to load your collection due to an error, Unable to load your delegates due to an error. In general, arthroscopic debridement is preferred to open debridement when the pathology is largely intra-articular. MRI can confirm and define the extent of a suspected fibrotic lesion and assist in detecting and differentiating other postoperative complications with a similar clinical presentation. Cyclops lesion which represents arthrofibrosis in midline anterior knee. A sagittal proton density-weighted image demonstrates a diffuse fibrotic reaction encasing the ACL graft with a cyclops lesion anterior to the ACL graft (arrow) and fibrosis posterior to the ACL graft (asterisk) extending to the posterior capsule. 2007; 15:144--146, Knee Surgery, Sports Traumatology, Arthroscopy.
