Introduction: Augmented reality is an innovative technology which superimposes virtual reality images onto a real world. It can visualize an affected lesion hidden by normal structures. We’ve introduced this computer-aided technique into the arthroscopic surgery. The purpose of this study is to examine the usefulness of the augmented reality navigation system in the arthroscopic surgery. Materials & Methods: The navigation system for arthroscopic surgery was built with new designed arthroscopy for navigation and modified point to point registration using the customized reference stay with optical markers. We designed 10 models of osteochondritis dissecans (OCD) knees with Sawbones®. 3D OCD knee models were made from CT knee data set using the 3-D reconstruction algorithm. CT was performed with skin fiducial markers. Registration was performed using skin markers and Poraris® optical tracking system. The accuracy of registration and that of image overlay using new devices were evaluated. Results: The accuracy of registration by using the new devices was mean 0.94±0.74 mm. The overlay accuracy was mean 3.51±2.64 mm on 2D monitor and 5.76±3.91 mm on 3D space. Conclusion: Augmented Reality would be a useful help for arthroscopic surgery not only in the treatment of OCD lesion but also in the treatment of ACL injury, the visualization of tumor site and important vessels.
