The Accuracy of Bone Tunnel Position Using Fluoroscopic-Based Navigation System in ACL Reconstruction

INTRODUCTION The most common cause of technical failure in anterior cruciate ligament (ACL) reconstruction is the bone tunnel misplacement(1). However it is technically challenging to place the bone tunnel in the anatomically correct position. The aim of this study was to prove the hypothesis that fluoro-based navigation system contribute to the accuracy and reproducibility of bone tunnel placements in single-bundle ACL reconstruction thereby potentially leading to better clinical results than those of conventional method. And its application for doublebundle ACL reconstruction, which still remains lack of reliable technique, was also discussed from the aspects of radiographic and clinical outcomes.
