Precision of Tunnel Execution in Navigated Anterior Cruciate Ligament Reconstruction

Anterior cruciate ligament (ACL) reconstruction is one of the most common orthopedic procedures in sports medicine. As the number of ACL reconstructions have increased, ACL revision surgery is increasing. Nonanatomic femoral and tibial tunnel placement is an important cause of failure of ACL reconstruction. Unfortunately, accurate tunnel placement can be difficult with current techniques, even for experienced surgeons. Computer-assisted surgery and navigation system can provide precise information about tunnel location and impingement, and may reduce the rate of revision surgery. The operative technique and the results of ACL reconstruction with navigation are described.
