Abstract
Purpose: To inform the integration of the insight ARTHRO VR® training simulator into a curriculum for U.W.O. orthopaedic surgery residents by constructing performance curves for experts and novices performing simulated arthroscopic procedures.
Methods: This was a pilot prospective cohort study. Participants were divided into two groups by arthroscopy experience: experts (n = 8) and novices (n = 10). Each participant performed six repetitions of four procedures. Performance measures were provided by the VR simulator and included time to completion, distance covered, and roughness. Scores for each parameter were summed for every session and performance curves were constructed by plotting the group mean and standard deviation.
Results: Novices improved consistently in all parameters measured without reaching a plateau by the sixth session, while experts demonstrated a steeper initial improvement but reached a plateau as early as the second session. Experts outperformed novices in terms of time and distance covered, but by the last session, novices approached expert levels for all parameters measured. The VR simulator also demonstrated construct validity by successfully distinguishing between expert and novice groups (Mann‐Whitney U Test p < 0.01).
Conclusions: This pilot study provided preliminary evidence to inform the integration of the insight ARTHRO VR® simulator into a training curriculum by establishing factors like the amount of training necessary to achieve an expert level of skill. While the virtual reality simulator improves the performance of novices in simulated arthroscopy, its ability to teach arthroscopic skills that are transferrable to a real operating room environment requires further study.
