A navigation system has been developed for minimally invasive knee-joint surgery in this study. Registrations between patient and images are performed by use of surface matching. The registration method are less invasive than other methods such as attaching markers directly to patient or using X-ray images for image-based registration. The system is also integrated with a three dimensional (3D) display, which can visualize 3D images of the anatomical structures as well as the peripheral equipments. Feasibility studies with a set of experiments showed that the registration position error was less than 1.0 mm and determination of the insertion path was 3 times faster than the conventional method. With improvements of the quality of the 3D display and the registration method, the system is possible to be utilized in knee-joint surgery.
