Objective: To assess the face, content and construct validity of a virtual reality hip arthroscopy simulator. Design: Participants were divided into expert or novice groups, dependent on whether they had assisted on or performed more than 50 hip arthroscopy procedures. Participants were given a standardized introduction and shown a video on how to use the simulator. They were given a 5 minute diagnostic task to complete, to familiarise themselves with the equipment. Participants then undertook a therapeutic task. On completion, the simulator produced a summary of performance metrics for the domains: Operation time, Safety, Economy, Detailed Visualization and Overall Score. A 7-point Likert scale questionnaire was completed by participants to assess the face and content validity of the simulator. Setting: University lab or exhibition stand at orthopaedic conference. Participants: Clinicians from a hospital orthopaedic department or attendee at UK orthopaedic conference with varying levels of experience in hip arthroscopy surgery. Results: Twenty two participants were recruited. Six were classified as expert, 16 as novice. Statistically significant differences were found between experts and novice scores for ‘Overall Score’ (p=0.001), ‘Safety’ (p=0.002) and ‘Economy’ (p=0.033) domains but no difference was found for the ‘Detailed Visualization’ (p=0.097) domain. Questionnaire responses were positive for all items related to face and content validity. Conclusion: This study suggests that training on the ArthroSTM VR hip arthroscopy simulator has construct, face and content validity. It expands the evidence base for VR simulator training, and is the first study to evaluate the hip arthroscopy module.
