Summary
A new low-cost shoulder arthroscopy simulator effectively differentiates surgical skill levels. This validated training tool was accepted by all participants as useful for improving arthroscopic surgery proficiency.
Area of Science:
- Surgical Education
- Medical Simulation
- Orthopedic Surgery
Background:
- Arthroscopic surgery training requires effective and accessible simulation tools.
- Low-cost simulators can potentially democratize surgical skill acquisition.
Purpose of the Study:
- To validate a novel, low-cost shoulder arthroscopy simulator.
- To assess the simulator's acceptance and utility in medical training.
Main Methods:
- Ten medical students, ten orthopedic residents, and ten shoulder surgeons performed tasks on the simulator twice.
- Performance metrics included task completion time, lookdowns, and the Global Operative Assessment of Laparoscopic Skills (GOALS) score.
- Participant feedback was gathered using an adapted Likert scale.
Main Results:
- Shoulder surgeons outperformed students and residents in time and GOALS scores.
- All groups showed significant improvement upon task repetition, with surgeons and academics demonstrating statistically significant gains.
- A decrease in lookdowns and 100% participant acceptance of the simulator's usefulness were observed.
Conclusions:
- The developed simulator effectively distinguishes between varying levels of arthroscopic surgery expertise.
- The low-cost simulator is a validated and accepted tool for shoulder arthroscopy training.
