Sophisticated computer-based devices have become available to simulate the surgical experience in a protected environment. As with any new educational tool, these devices have generated controversy about the validity of the training experience. HYPOTHESIS: Performance on a virtual reality simulator correlates with actual surgical experience. STUDY DESIGN: Controlled laboratory study. METHODS: Forty-three test subjects of various experience levels in shoulder arthroscopy were tested on an arthroscopy simulator according to a standardized protocol. Subjects were evaluated for time to completion, distance traveled with the tip of the simulated probe compared with a computer-determined optimal distance, average probe velocity, and number of probe collisions with the tissues. RESULTS: Subjects were grouped according to prior experience with shoulder arthroscopy. Comparing the least experienced with most experienced groups, the average time to completion decreased by 62% from 128.8 seconds to 49.2 seconds; path length and hook collisions were more than halved from 8.2 to 3.8 and 34.1 to 16.8, respectively; and average probe velocity more than doubled from 0.18 to 0.4 cm/second. There were no significant differences for any parameter tested between subjects with video game experience compared to those without. CONCLUSIONS: The study demonstrated a close and statistically significant correlation between simulator results and surgical experience, thus confirming the hypothesis. Conversely, experience with video games was not associated with improved simulator performance. This indicates that the skill set tested may be similar to the one developed in the operating room, thus suggesting its use as a potential tool for future evaluation of surgical trainees. CLINICAL RELEVANCE: The results have implications for the future of orthopaedic surgical training programs, the majority of which have not embraced virtual reality technology for physician education. ------>tmu_sno=None ------>sno=3612 ------>authors2=None ------>authors3=None ------>authors4=None ------>authors5=None ------>authors6=None ------>authors6_c=None ------>authors=Tsai MD, Jou SB, Hsieh MS ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Surgical experience correlates with performance on a virtual reality simulator for shoulder arthroscopy. ------>language=2 ------>check_flag= ------>submit_date= ------>country=None ------>no= ------>patent_SDate=None ------>update_bywho= ------>publish_year=2000 ------>submit_flag= ------>publish_month=None |
