Resorbable screw and sheath versus resorbable interference screw and staples for ACL reconstruction: a comparison of two tibial fixation methods

The anterior cruciate ligament (ACL) reconstruction is one of the most performed and successful orthopaedic procedures. The results are considered independent by the choice of the graft and the fixation devices. A growing interest on resorbable non-metallic fixation devices versus standard metallic fixation devices has been noted over recent years with few clinical experiences reported in the literature. The aim of this study is to compare the clinical and radiological outcomes of patients undergoing ACL reconstruction using autologous hamstring tendons with tibial fixation by a centrally placed resorbable screw and sheath to a combination of an eccentrically placed resorbable interference screw and supplementary staple fixation.
