Rate of Insufficient Ipsilateral Hamstring Graft Harvesting in Primary Anterior Cruciate Ligament Reconstruction

Abstract

AbstractAnterior cruciate ligament (ACL) reconstruction, using an ipsilateral hamstring graft, may necessitate an alternative graft source if the obtained graft is insufficient with regards to length or diameter. The study aims to determine the rate of insufficient ipsilateral hamstring graft harvesting in primary ACL reconstruction. Retrospective review of 50 consecutive primary ACL reconstructions performed by a single surgeon in the United Kingdom. In 3 of 50 cases, there was insufficient ipsilateral hamstring graft harvesting and a contralateral hamstring graft was used. In two cases, this was due to premature division of the ipsilateral hamstring tendons (3/100 harvested tendons). In one case, an adequate length of semitendinosus was obtained, but its central portion was too thin. Retrospective review of preoperative magnetic resonance imaging identified the thin part of the tendon in the latter case. Insufficient ipsilateral hamstring graft harvesting is a recognized, yet unusual intraoperative complication in primary ACL reconstruction. Presurgical planning as to how to manage such complications is essential.
