Summary: The purpose of this study was to perform a new tibial fixation technique for anatomic ACL reconstruction with a hamstring graft and an outside-in femoral tunnel approach. The secondary purpose was to decrease the costs associated with this procedure. We inverted the graft with its bend into the tibial tunnel, where we performed suspension fixation with simple hardware (staple or screw+washer).

Abstract:

Purpose

The purpose of this study was to perform a new tibial fixation technique for anatomic ACL reconstruction with a hamstring graft and an outside-in femoral tunnel approach. The secondary purpose was to decrease the costs associated with this procedure. We inverted the graft with its bend into the tibial tunnel, where we performed suspension fixation with simple hardware.

Methods

Forty patients who underwent ACL reconstruction were divided into 2 groups: 20 patients received tibial fixation with a screw and washer, and 20 patients received tibial fixation with a staple. The graft was always fixed suspended on the device. The patients underwent postoperative physical examinations at 0, 3, 6 and 12 months with the subjective IKDC form and Lysholm score.

Results

The results were similar between the groups for all time points (p>0.05). Both groups improved over time (p<0.001), and these results aligned with the literature, without major complications.

Conclusion

The proposed technique for anatomic ACL reconstruction with hamstring graft inverted with its bend in the tibial tunnel with a suspension-type fixation with a screw and washer or staple and outside-in femoral tunnel technique reproduces results described in the literature, with lower hardware costs.
