| Outline of Final Research Achievements |
Precise osteochondroplasty is the most important factor in hip arthroscopic surgery for cam-type femoroacetabular impingement (FAI). Although computer-assisted surgery, particularly with a navigation system, may improve the accuracy of arthroscopic osteochondroplasty, few clinical studies have assessed its accuracy. The purpose of this study was to evaluate the accuracy of arthroscopic osteochondroplasty with a computed tomography (CT)-based navigation system for cam-type FAI, especially its effect on the deviation of the actual resection from preoperative planning.
Navigation-assisted arthroscopic osteochondoroplasty showed generally favorable overall accuracy. Under-resection was more frequent than over-resection on the anterior-superior side of the femur, even with the assistance of the navigation system.
