Shaping the Future of Surgical Training

Historically, surgical training has often been summarized by the phrase “see one, do one, teach one.” Modern surgical education is increasingly structured, competency-based, and focused on patient safety. However, hands-on training opportunities remain limited due to supervision requirements, and the risks and costs associated with practicing on real patients or cadaveric specimens. The PROFICIENCY project aims to enhance surgical training by providing a safe, repeatable, and cost-effective environment using extended reality (XR) technologies. 

Compared to conventional virtual simulators, our system allows resident surgeons to practice using real surgical instruments on physical bone models, creating a more realistic tactile experience. Augmented reality glasses overlay step-by-step procedural guidance directly into the user’s field of view, and the precise tracking of instruments enables real-time feedback on performance. This setup supports self-directed training and helps reduce the need for continuous expert supervision. 

Currently, the XR Training Simulator focuses on total hip replacement, a technically demanding and high-impact orthopedic procedure, requiring precise spatial orientation, careful handling of instruments, and adherence to a well-defined sequence of steps. By combining physical interaction with autonomous digital guidance, the simulator allows trainees to repeatedly practice critical parts of the procedure, receive immediate feedback on their technique, and build confidence before entering the operating room - ultimately contributing to better patient outcomes.
