Development of simulated arthroscopic skills.

Area of Science:

• Surgical Education
• Medical Simulation
• Orthopedic Surgery

Background:

• Virtual reality (VR) simulation is increasingly used in surgical training.
• Previous research indicates a correlation between arthroscopic experience and VR performance.
• The learning curve for novice surgeons in arthroscopic procedures requires effective training methods.

Purpose of the Study:

• To analyze the skill development of inexperienced surgeons undergoing VR training for shoulder arthroscopy.
• To evaluate the impact of a structured VR training program on surgical performance metrics.

Main Methods:

• 14 inexperienced surgeons were randomized into an intervention group (receiving 5-hour VR training) and a control group.
• An experienced surgeon group served as an additional control.
• All participants were tested twice on the insightMIST arthroscopic VR trainer over 6-15 days.

Main Results:

• The intervention group showed a significant reduction in average arthroscopy time (720 to 223 seconds, p=0.03).
• Camera travel distance was significantly reduced in the intervention group (367 to 84 cm, p=0.02).
• Improvements were observed in depth of collisions, probe distance, and collision count, though not all reached statistical significance.

Conclusions:

• VR training offers a viable method for novice surgeons to acquire fundamental navigation skills for arthroscopic surgery.
• Further research is needed to confirm the transferability of VR-acquired skills to the actual operating room environment.
