   Introduction
 
Although reconstruction of the anterior cruciate ligament (ACL) is a common procedure, accurate and reproducible placement and tensioning of the graft remain difficult tasks. We introduce a proof-of-concept prototype that demonstrates how the combination of an intuitive interface and a surgical navigation system can address the difficulties associated with selecting and evaluating a graft site.

KneeNav-ACL is a surgical navigation system that was created to enable surgeons to evaluate ligament placement and performance before committing to an attachment site and also to provide surgeons with subsequent tooling guidance once satisfactory ligament insertion locations have been determined.

Image Overlay is a novel visualization technology with the potential to be of considerable utility in the operating-room setting. Image Overlay utilizes a partially reflecting mirror to display relevant geometric and procedural information within the surgeon's general line of sight. The result is a type of "heads-up" display for clinical use.
