The Effect of Interference Screw Diameter on Fixation of Soft-Tissue Grafts in Anterior Cruciate Ligament Reconstruction

Conclusions: All interference screws tested provided adequate fixation strength. The results of this study show no statistical significance for ultimate strength or graft slippage with variable screw diameter. Clinical Relevance Aperture fixation with the interference screw technique provides adequate stability for soft-tissue grafts in ACL reconstruction. Although no statistical significance was found, there was a trend toward less graft-site motion when we used a screw diameter equal to tunnel size.
