This study aimed to determine the effect of a simulation course on gaze fixation strategies of participants performing arthroscopy.
Participants (n = 16) were recruited from two one-day simulation-based knee arthroscopy courses, and were asked to undergo a task before and after the course, which involved identifying a series of arthroscopic landmarks. The gaze fixation of the participants was recorded with a wearable eye-tracking system. The time taken to complete the task and proportion of time participants spent with their gaze fixated on the arthroscopic stack, the knee model, and away from the stack or knee model were recorded.
Participants demonstrated a statistically decreased completion time in their second attempt compared to the first attempt (P = 0.001). In their second attempt, they also demonstrated improved gaze fixation strategies, with a significantly increased amount (P = 0.008) and proportion of time (P = 0.003) spent fixated on the screen vs. knee model.
Simulation improved arthroscopic skills in orthopaedic surgeons, specifically by improving their gaze control strategies and decreasing the amount of time taken to identify and mark landmarks in an arthroscopic task.
本研究旨在确定模拟课程对进行关节镜检查的参与者注视固定策略的影响。
从两个为期一天的基于模拟的膝关节镜检查课程中招募参与者（n = 16），并要求他们在课程前后各进行一项任务，该任务包括识别一系列关节镜下的标志。使用可穿戴式眼动追踪系统记录参与者的注视情况。记录完成任务所需的时间以及参与者注视关节镜堆叠物、膝关节模型以及远离堆叠物或膝关节模型的时间比例。
与第一次尝试相比，参与者在第二次尝试时完成任务的时间在统计学上显著缩短（P = 0.001）。在第二次尝试中，他们还表现出更好的注视固定策略，注视屏幕相对于膝关节模型的时间量（P = 0.008）和时间比例（P = 0.003）均显著增加。
模拟提高了骨科医生的关节镜检查技能，特别是通过改善他们的注视控制策略并减少在关节镜任务中识别和标记标志所需的时间。
