Bone Tunnel Widening After Anterior Cruciate Ligament Reconstruction Using EndoButton or EndoButton Continuous Loop

Abstract

PURPOSE: This study investigated the effect of the EndoButton CL (Smith & Nephew, Andover, MA) used for femoral graft fixation during anterior cruciate ligament reconstruction compared with an EndoButton with knot-fixed polyester tape on femoral and tibial bone tunnel widening and clinical outcome. METHODS: A retrospective case-control study design was used. We compared 120 patients with EndoButton CL femoral fixation with 120 patients with an EndoButton with knot-fixed polyester tape. All patients had hamstring grafts and EndoButton femoral fixation and tibial fixation with a 7 x 30-mm metal interference screw. Tunnel widening was measured on anteroposterior (AP) and lateral radiographs at ..
