Abstract
The efficacy of virtual reality (VR) as a teaching augment for arthroplasty has not been well examined for unfamiliar multistep procedures such as unicompartmental knee arthroplasty (UKA). This study sought to determine whether VR improves surgical competence over traditional procedural preparation when performing a UKA. Twenty-two orthopaedic surgery trainees were randomized to two surgical preparation cohorts: (1) "Guide" group (control) with access to manufacture's technique guide and surgical video and (2) "VR" group with access to an immersive commercially available VR learning module. Surgical performance of UKA on a SawBone model was assessed through time and the Objective Structured Assessment of Technical Skills (OSATS) validated rating system. Participants were equally distributed among all training levels and previous exposure to UKA. No difference in mean surgical times was observed between Guide and VR groups (Guide = 42.4 minutes versus VR = 43.0 minutes; P = 0.9) or mean total OSATS (Guide = 15.7 versus VR = 14.2; P = 0.59). Most trainees felt VR would be a useful tool for resident education (77%) and would use VR for case preparation if available (86.4%). In a randomized controlled trial of trainees at a single, large academic center performing a complex, multistep, unfamiliar procedure (UKA), VR training demonstrated equivalent surgical competence compared with the use of traditional technique guides, as measured by surgical time and OSATS scores. Most of the trainees found the VR technology beneficial. This study suggests that VR technology may be considered as an adjunct to traditional surgical preparation/training methods.
