PURPOSE
To test the face validity of the hip diagnostics module of a virtual reality hip arthroscopy simulator.
METHODS
A total of 25 orthopaedic surgeons, 7 faculty members and 18 orthopaedic residents, performed diagnostic supine hip arthroscopies of a healthy virtual reality hip joint using a 70° arthroscope. Twelve specific targets were visualised within the central compartment; six via the anterior portal, three via the anterolateral portal and three via the posterolateral portal. This task was immediately followed by a questionnaire regarding the realism and training capability of the system. This consisted of seven questions addressing the verisimilitude of the simulator and five questions addressing the training environment of the simulator. Each question consisted of a statement stem and 10-point Likert scale. Following similar work in surgical simulators, a rating of 7 or above was considered an acceptable level of realism.
RESULTS
The diagnostic hip arthroscopy module was found to have an acceptable level of realism in all domains apart from the tactile feedback received from the soft tissue. 23 out of 25 participants (92%) felt the simulator provided a non-threatening learning environment and 22 participants (88%) stated they enjoyed using the simulator. It was most frequently agreed that the level of trainees who would benefit most from the simulator were registrars and fellows (22 participants; 88%). Additionally, 21 of the participants (84%) agreed that this would be a beneficial training modality for foundation and core trainees, and 20 participants (80%) agreed that his would be beneficial for consultants.
CONCLUSIONS
This VR hip arthroscopy simulator was demonstrated to have a sufficient level of realism, thus establishing its face validity. These results suggest this simulator has sufficient realism for use in the acquisition of basic arthroscopic skills and supports its use in orthopaedics surgical training.

目的
测试虚拟现实髋关节镜检查模拟器髋关节诊断模块的表面有效性。
方法
共 25 名骨科医生，7 名教员和 18 名骨科住院医师，使用 70°关节镜对健康的虚拟现实髋关节进行诊断性仰卧髋关节镜检查。在中央隔室中可视化了 12 个特定目标；6 个通过前入路，3 个通过前外侧入路，3 个通过后外侧入路。完成此任务后，立即对系统的逼真度和培训能力进行问卷调查。问卷包括七个问题，用于评估模拟器的逼真度，五个问题用于评估模拟器的培训环境。每个问题都包含一个陈述项和 10 分制的李克特量表。根据类似的手术模拟器工作，评分在 7 分或以上被认为是可以接受的逼真度水平。
结果
在除了从软组织接收到的触觉反馈之外的所有领域，诊断性髋关节镜检查模块都被认为具有可接受的逼真度。25 名参与者中有 23 名（92%）认为模拟器提供了一个无威胁的学习环境，22 名参与者（88%）表示他们喜欢使用模拟器。大多数参与者都同意，最受益于模拟器的学员是住院医师和研究员（22 名；88%）。此外，21 名参与者（84%）同意这将是一种有益的培训模式，适用于基础和核心学员，20 名参与者（80%）同意这将对顾问有益。
结论
本虚拟现实髋关节镜检查模拟器具有足够的逼真度，从而确定其表面有效性。这些结果表明，该模拟器具有足够的逼真度，可用于获得基本关节镜技能，并支持其在骨科手术培训中的应用。
