Bone Tunnel Widening with Autogenous Bone Plugs Versus Bioabsorbable Interference Screws for Secondary Fixation in ACL Reconstruction

Abstract

The clinical results associated with bioabsorbable screws and bone plugs were not significantly different. Laxity evaluation demonstrated no significant differences between bioabsorbable screws and bone plugs. Compared with bioabsorbable interference screws, autogenous bone plugs reduced the complication rate and tibial tunnel widening without inducing instability. We believe that an autogenous bone plug for the tibial tunnel is a reasonable option in selected patients.
