Background. There are several fixation techniques and devices available for ACL reconstruction, which differ significantly in their efficacy. There are no studies in the literature comparing femoral transfixation pins (Rigidfix) and adjustable loop (Rigid-loop) devices. We compared the outcomes of these devices in our study. Methods. A retrospective observational cohort study was done between November 2017 and June 2019. Of the total 95 cases, initial 47 patients had undergone graft fixation with Rigidfix and the subsequent 48 underwent fixation with Rigidloop. Clinical and functional evaluation of these patients was done at one-year follow-up and the results were compared. Results. The two groups were homogenous demographically. Though better outcome and functional scores were noted in the Rigidfix group, these observations were not statistically significant. Two Rigidloop cases had side to side difference in KT-1000 reading of > 5 mm with a fair outcome. Conclusions. Fixation of the hamstring autograft on the femoral side using Rigidfix cross pin and Rigidloop adjustable suspensory devices provide statistically compara-ble stability. The Lysholm grading and IKDC-2000 functional scores between both the groups were similar at one-year follow-up and hence can be used interchangeably intraoperatively if a need arises without any consequences.
