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).
