Methods: This retrospective study evaluated 187 patients who underwent arthroscopic ACL reconstruction. The patients included in the study were categorized into two groups according to the type of femoral suspensory button (FSB) implant used: fixed suspensory button (FxSB) and adjustable suspensory button (ASB). Button malpositions were determined and recorded with intraoperative images in cases where fluoroscopy was used and postoperative X-ray radiographs in cases where fluoroscopy was not used. Malposition rates were compared between the two groups, and risk analysis was performed.
Results: The FxSB implant was used in 89 patients, and the ASB implant was used in 98 patients. Malposition was detected in 24 patients (12.8%). When the FxSB and ASB implant groups were analyzed separately, the number and rate of malpositions were 5 (5.6%) and 19 (19.3%), respectively (p=.0123). Regression analysis showed that the risk of malposition was 3.5 times higher in the ASB implant group than in the FxSB implant group (M: 3.57 (p=.0017) 95% CI (1.36-10.1)). Conclusion: This study found that ASB implants used in ACL reconstruction resulted in a higher rate of button malposition than FxSB implants. In addition, intraoperative fluoroscopy was found to be a useful method to detect malpositions in all FSB implants and allow for proper button positioning with intraoperative interventions.}, number={2}, publisher={Merthan TUNAY}
