ARTHROSCOPY SKILLS DEVELOPMENT WITH A SURGICAL SIMULATOR: A COMPARATIVE STUDY IN ORTHOPAEDIC SURGERY RESIDENTS

The International Society for Technology in Arthroplasty (ISTA), 27th Annual Congress. PART 2.



Abstract

Introduction

Junior level orthopaedic surgery residents who train with a virtual surgical simulator can lead to improved arthroscopy performance.

Methods

Study participants were first and second year orthopaedic surgery residents at a single institution who were randomized to either train on the virtual reality surgical simulator (Insight Arthro VR) for a total of 2.5 hours (n=8) or receive 2 hours of didactic lectures with models (non-simulator) (n=6). Both groups were then evaluated in both knee and shoulder arthroscopy using a cadaver. Performance was measured by time to completion of a standardized protocol checklist and cartilage-grading index (CGI) (scale 0–10).

Results

All subjects had no previous arthroscopy experience prior to the study. The simulator group had a shorter time to completion in both knee (simulator: 5.1 ± 1.8 min, non-simulator: 8.0 ± 4.4 min; p=0.09) and shoulder (simulator: 6.1 ± 1.5 min, non-simulator: 9.9 ± 3.2 min; p=0.02) arthroscopy. Similarly, the simulator group had improved CGI scores in both the knee (simulator: 4.0 ± 1.1, non-simulator: 5.3 ± 1.5; p=0.07) and shoulder (simulator: 3.4 ± 0.8, non-simulator: 5.5 ± 1.6; p=0.008) arthroscopy.

Discussion and Conclusion

This study suggests that surgical simulators are beneficial in arthroscopy skills development for orthopaedic surgery residents.
