VR-ORS: Virtual Reality in Orthopaedic Surgical Education: A Randomized Controlled Trial
Study Details
Study Description
Brief Summary
Immersive virtual reality (IVR) surgical simulators are increasingly being used for learner education. The aim of this randomized controlled trial is to compare the efficacy of IVR to hands-on orthopaedic workshop sessions (such as arthroscopy simulators, cadaveric models, and Sawbones®) in various orthopaedic subspecialties (such as sports, arthroplasty, and spine surgery).
Overall, in this multi-stage comprehensive randomized controlled the aim is to assess:
-
If IVR simulation using head-mounted displays (HMD) is superior to the current standard of training for orthopaedic surgery residents and medical students.
-
Determine if it is feasible to incorporate immersive headset virtual reality simulation into residency training programs and medical school curriculums.
-
Assess the longitudinal application of IVR training on medical student and resident surgical education.

Detailed Description
Study Stages:
Stage 1 - Medical students and orthopaedic residents participating in the Canadian Orthopaedic Surgery Medical Education Course 2023 (COSMEC) will be selected and computer randomized (1:1) into two groups of experimental (IVR) and control (arthroscopy simulator box), based on level of training. Allocation concealment will be ensured using central randomization. Trainees in both groups will receive a common didactic training for knee arthroscopy. Subsequently, trainees in the experimental group will undergo a IVR surgical training module and trainees in the control group will undergo a similar module using arthroscopy simulator box. Following the training modules, participants will complete knowledge tests, technical skill assessments on knee arthroscopy simulators, and experiential surveys.
Stage 2 - Medical students and orthopaedic residents participating in the 2023 University of Toronto Orthopaedic Surgery bootcamp will be selected and computer randomized (1:1) into two groups of experimental (IVR) and control (sawbones), based on level of training. Allocation concealment will be ensured using central randomization. Trainees in both groups will receive a common didactic training for femoral intramedullary nail (IMN) placement. Subsequently, trainees in the experimental group will undergo a IVR surgical training module and trainees in the control group will undergo a similar module using Sawbones ®. Following the training modules, participants will complete knowledge tests, technical skill assessments on cadaveric models, and experiential surveys.
Stage 3 - The protocol explained in stage 1 and 2 may be repeated for various orthopaedic sub-speciality (including arthroplasty and spine surgery) for the participants in the booth camp.
Stage 4 - All trainees may then be followed longitudinally over the course 6 months. Trainees' performance may be evaluated for procedures in which training was provided, based on preceptor evaluations (for example by completing standardised evaluation forms) on a voluntary basis.

Outcome Measures
Primary Outcome Measures
- Objective Structured Assessment of Technical Skills (OSATS) [2 weeks after the training sessions, over 30 minutes testing period]
The primary outcome of the study is to assess trainee procedural performance using simulators or cadaveric models between the experimental (IVR) and control groups, measured by Objective Structured Assessment of Technical Skill (OSATS) score.
Secondary Outcome Measures
- Global Ratings Scale (GRS) [2 weeks after the training sessions, over 30 minutes testing period]
GRS will be used as a secondary outcome measure to evaluate the performance of the surgical trainees who will be participating in the study. The GRS scores will be recorded by expert evaluators who will observe the trainees performing the surgical procedure. The scores will be analyzed to assess the effect of the intervention on the overall performance of the trainees.
- Hand and body motion analysis using sensors [2 weeks after the training sessions, over 30 minutes testing period]
Motion analysis is used to evaluate the effectiveness of the training intervention and can help identify areas for improvement in surgical technique. By incorporating this objective measure, we can gain a more comprehensive understanding of the impact of the training interventions on surgical performance.
- Experimental and confidence questionnaire [2 weeks after the training sessions, over 30 minutes testing period]
Experimental and confidence questionnaire will be used to assess the participants' confidence level and perception of their own skills in performing the simulated laparoscopic task. This questionnaire will include questions regarding their comfort level with the equipment, confidence in their ability to complete the task accurately and efficiently, and their overall perception of their own skill level. The questionnaire will be administered after each simulation session and will be used to assess any changes in the participants' confidence and perception of their own abilities throughout the study. The results of this questionnaire will provide valuable insight into the participants' perceived skill level, and may be used to inform future training programs or interventions aimed at improving surgical skills.
- Time to complete the procedure [2 weeks after the training sessions, over 30 minutes testing period]
This secondary outcome will measure the total time required to complete the procedure, from the start of the procedure to the end. The time will be recorded in minutes using a stopwatch, and any breaks or interruptions during the procedure will be noted.
