The cyclops lesion after bicruciate-retaining total knee replacement Su EP, Su SL, Valle AG Della. The cyclops lesion, a well-known complication of ACL reconstruction surgery, is an ovoid fibroproliferative nodule found anterior to the ACL graft. So just wanted to add that it seems like scar tissue can maybe still be an issue even if it doesn't form a true cyclops. Previous studies reported that after ACL reconstruction, the incidence of joint stiffness was between 4 and 38% [8]. An arthroscopy four months after the original surgery showed a cyclops lesion at the roof of the femoral intercondylar notch the inverted cyclops lesion (Fig 1). Previous studies reported that after ACL reconstruction, the incidence of joint stiffness was between 4 and 38% [8]. A second arthroscopy is then needed to remove the nodule of scar tissue in order to regain extension (2). It could be that the old ACL stump has a protective effect on the graft.

The Pseudocyclops lesion is a rare complication of the arthroscopic reconstruction of the ACL in which a partial graft tear occurs and subsequently the torn fibres are flipped anteriorly mimicking a Cyclops lesion. Cyclops Lesions That Occur in the Absence of Prior Anterior Ligament Reconstruction1. Cyclops lesions are located just above the tibial tunnel and cause loss of knee range of motion with a mechanical block that restricts getting the leg completely straight following surgery. 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. The reconstruction was performed using a four-strand hamstring graft and fixed on the femoral side using the TransFix technique and Bio-Interference screw (Arthrex, Naples, FL, US) fixation for the tibial side. Cyclops lesions detected by MRI are frequent findings after ACL eCollection 2009.
