Methods: A single-center, retrospective chart review identified 1,902 patients between the ages of 8 and 66 yr who had ACL reconstruction between January 1, 2000, and October 31, 2015. Usually the patient will also have some quadriceps dysfunction. Torn anterior ACL graft fibers remain continuous with the graft in the tibial tunnel and are folded anteriorly (arrows) resulting in a pseudocyclops lesion. With this treatment, patients have a higher level of satisfaction, resolution of knee pain, return of physiological hyperextension (-5), optimal biomechanical joint movement and restoration of activity levels comparable to that following uncomplicated ACL reconstruction.

Another study reported an incidence of 47% within the first year, though symptoms were only present for about 10% of these cases (Kambhampati et al, 2020). 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. It can block the knee range of movement, limiting the full extension of the knee, and can therefore cause quadriceps dysfunction. Association of fibrosis in the infrapatellar fat pad and degenerative cartilage change of patellofemoral joint after anterior cruciate ligament reconstruction. Apply a low load on top of the knee and hold this for a prolonged period e.g 15 minutes.

The accuracy and reproducibility of magnetic resonance imaging (MRI) scans in . Despite such prevalence, cyclops lesions generally have minimal or no clinical symptoms, and their presence does not portend an inferior clinical outcome, with only 2% of cyclops lesions prompting surgical intervention.9 Symptomatic lesions present with loss of extension, snapping, catching, and painful extension with walking and/or running resulting in the cyclops syndrome. 7,8, MRI can assist in distinguishing cyclops lesions from other pathology that may limit knee extension, including roof impingement of the ACL graft (Figure 5), intra-articular bodies (Figure 6), and displaced torn ACL graft fibers. Arthroscopic release of anterior interval adhesions is also successful in relieving pain and restoring range of motion. He said it sounds like either patellofemoral pain syndrome or a cyclops lesion, but sounds more like patellofemoral, so he got me back in physical therapy and said if it still persists in a few months to come back and he'll get me scheduled for an MRI to check for the cyclops lesion.
