title: Correlation Between Arthroscopy Simulator and Video Game Performance: A Cross-Sectional Study of 30 Volunteers Comparing 2- and 3-Dimensional Video Games.
abstract: To investigate the association between arthroscopy simulator performance and video game skills.
  
  
  
  This study compared the performances of 30 volunteers without experience performing arthroscopies in 3 different tasks of a validated virtual reality knee arthroscopy simulator with the video game experience using a questionnaire and actual performances in 5 different 2- and 3-dimensional (D) video games of varying genres on 2 different platforms.
  
  
  
  Positive correlations between knee arthroscopy simulator and video game performances (ρ = 0.63, P < .001) as well as experiences (ρ = 0.50, P = .005) were found. The strongest correlations were found for the task of catching (hooking) 6 foreign bodies (virtual rings; "triangulation") and the dribbling performance in a sports game and a first-person shooter game, as well as the meniscus resection and a tile-matching puzzle game (all ρ ≥ 0.60, P < .001). No correlations were found for any of the knee arthroscopy simulator tasks and a strategy game.
  
  
  
  Although knee arthroscopy performances do not correlate with 2-D strategy video game skills, they show a correlation with 2-D tile-matching puzzle games only for easier tasks with a rather limited focus, and highly correlate with 3-D sports and first-person shooter video games. These findings show that experienced and good 3-D gamers are better arthroscopists than nonexperienced and poor 3-D gamers.
