Virtual Reality Simulation Facilitates Resident Training in Total Hip Arthroplasty: A Randomized Controlled Trial

Published:April 08, 2019DOI:https://doi.org/10.1016/j.arth.2019.04.002

      Abstract

      Background

      No study has yet assessed the efficacy of virtual reality (VR) simulation for teaching orthopedic surgery residents. In this blinded, randomized, and controlled trial, we asked if the use of VR simulation improved postgraduate year (PGY)-1 orthopedic residents’ performance in cadaver total hip arthroplasty and if the use of VR simulation had a preferentially beneficial effect on specific aspects of surgical skills or knowledge.

      Methods

      Fourteen PGY-1 orthopedic residents completed a written pretest and a single cadaver total hip arthroplasty (THA) to establish baseline levels of knowledge and surgical ability before 7 were randomized to VR-THA simulation. All participants then completed a second cadaver THA and retook the test to assess for score improvements. The primary outcomes were improvement in test and cadaver THA scores.

      Results

      There was no significant difference in the improvement in test scores between the VR and control groups (P = .078). In multivariate regression analysis, the VR cohort demonstrated a significant improvement in overall cadaver THA scores (P = .048). The VR cohort demonstrated greater improvement in each specific score category compared with the control group, but this trend was only statistically significant for technical performance (P = .009).

      Conclusions

      VR-simulation improves PGY-1 resident surgical skills but has no significant effect on medical knowledge. The most significant improvement was seen in technical skills. We anticipate that VR simulation will become an indispensable part of orthopedic surgical education, but further study is needed to determine how best to use VR simulation within a comprehensive curriculum.

      Level of Evidence

      Level 1.
