Anterior Cruciate Ligament Reconstruction Using the Endobutton Continuous Loop Bone–Tendon–Bone Fixation System

Introduction

The Endobutton continuous loop (CL) bone–tendon–bone (BTB) Fixation System (Smith and Nephew, Andover, Massachusetts) is a technique for fixation of anterior cruciate ligament (ACL) grafts that have a bone block for the femoral tunnel, such as BTB autografts, BTB allografts, Achilles tendon allografts, and quadriceps tendon grafts. The Endobutton-CL BTB System offers surgeons many advantages over current fixation methods of the femoral bone plug.
