Virtual reality (VR) training effectiveness in improving hip arthroplasty surgical skills requires further evaluation. We hypothesised VR training could improve accuracy and the time taken by medical students compared to a control group with only video teaching.
This single-centre randomized controlled clinical trial collected data from March to June 2023. Surgically naïve volunteer undergraduate medical students performed three sessions on a VR training platform, either cup (VR-Cup=Control-Stem) or stem (VR-Stem=Control-Cup) implantation. The primary outcome was the mean difference between predefined cup inclination (60°) and stem anteversion (20°) compared to the actual implanted values in sawbones between VR and control groups. Secondary outcomes were task completion time and mistake number between the groups.
A total of 101 students participated (VR-Cup 47, VR-Stem 54). Groups did not significantly differ concerning age (p = 0.879), gender (p = 0.408), study year (p = 0.938), previous VR use (p = 0.269) and baseline medical and procedural knowledge. The VR-Cup implanted the cup closer to the intended target (p < 0.001) and faster than the Control-Cup group (p = 0.113). The VR-Stem implanted the stem closer to the intended target (p = 0.008) but not faster than the Control-Cup group (p = 0.661). Stem retroversion was commoner in the Control-Stem than in the VR-Stem group (p = 0.016).
VR training resulted in higher rates of accurate procedure completion, reduced time and fewer errors compared to video teaching. VR training is an effective method for improving skill acquisition in THA.

虚拟现实（VR）培训在改善髋关节置换手术技能方面的效果需要进一步评估。我们假设 VR 培训可以提高准确性，并减少医学生的时间，与仅接受视频教学的对照组相比。
这项单中心随机对照临床试验于 2023 年 3 月至 6 月收集数据。未经手术的志愿本科医学生在 VR 培训平台上进行了三次训练，分别为杯（VR-Cup=Control-Stem）或柄（VR-Stem=Control-Cup）植入。主要结果是在 VR 和对照组之间，在使用 VR 培训和对照组培训后，在人工骨上预先设定的杯倾斜度（60°）和柄前倾角（20°）与实际植入值之间的平均差异。次要结果是两组之间的任务完成时间和错误数量。
共有 101 名学生参加（VR-Cup47 名，VR-Stem54 名）。两组在年龄（p = 0.879）、性别（p = 0.408）、学习年限（p = 0.938）、以前使用 VR（p = 0.269）和基线医学和程序知识方面没有显著差异。与 Control-Cup 组相比，VR-Cup 组植入的杯更接近目标（p < 0.001）且速度更快（p = 0.113）。VR-Stem 组植入的柄更接近目标（p = 0.008），但速度不如 Control-Cup 组（p = 0.661）。与 VR-Stem 组相比，Control-Stem 组的柄后倾更为常见（p = 0.016）。
与视频教学相比，VR 培训在提高程序完成的准确性、减少时间和减少错误方面效果更好。VR 培训是一种有效的 THA 技能获取方法。
