Abstract
Object
Computer-aided technology can decrease the difficulty associated with arthroscopic hip surgery. Our computer-aided system helps to navigate in the hip joint during arthroscopy by (1) tracking tool position with a linkage of encoders, and (2) using 3D computer graphics to indicate the tool position relative to the patient anatomy. This paper presents a study of user performance to verify the effectiveness of this computer-aided system for hip arthroscopy as a part of continued work on this project.
Materials and methods
A user study was completed to determine if the computer-aided system could help reduce task completion time and tool-path length. The time and path length provide a measure of operation time and potential tissue damage, respectively. Ten participants completed a simple navigation task with and without the assistance of the computer-aided system.
Results
A time reduction of 38% and a path length decrease of 72% were achieved with the computer-aided system, confirming its effectiveness. A user survey provided overall positive feedback regarding the system. The survey information also suggested areas of improvement for continued research.
Conclusion
The proposed computer-aided system can be used to address the challenges of arthroscopic hip surgery by reducing operation time and improving patient safety.
