Application of 3D-Printed Personalized Guide for Lateral Femoral Positioning in Anterior Cruciate Ligament Reconstruction of the Knee.

Objective: This research aims to investigate the effectiveness of 3D computer-assisted customized guided positioning of the lateral femoral tunnel compared to conventional methods for Anterior Cruciate Ligament (ACL) reconstruction surgery.

Methods: A total of 80 patients with a complete ACL tear who underwent arthroscopic reconstruction with autologous tendon transplantation (semitendinosus-gracilis tendon) were included in this study. The patients were admitted to our hospital between March 2020 and January 2022 and were randomly divided into two groups: the conventional group (n = 40) and the personalized guide group (n = 40), based on the positioning method.
