| Summary: | <p><strong>Objectives:</strong> To determine the validity of a novel virtual reality (VR) platform in assessing acetabular component orientation (inclination and version) in a simulated model.</p>
<p><>strong>Methods:</strong> An acetabular cup was manually implanted into a pelvis sawbone across a range of orientations. Simultaneous readings were obtained from the VR system and another validated system (Vicon®) for comparison.</p>
<p><strong>Results:</strong> 55 readings were obtained. The mean average difference in acetabular cup version and inclination between the Vicon and VR systems was 3.4°, and -0.005° respectively. Strong positive correlations were demonstrated in both version (Pearson’s R = 0.92, p<0.001), and inclination (Pearson’s R = 0.94, 99, p<0.001). The adjusted R2 on linear regression for version was 0.84, and 0.88 for inclination.</p>
<p><strong>Conclusion:</strong> The VR platform is highly accurate and reliable in determining acetabular component orientation in a simulated environment, which may be modified for use in a range of settings.</p>
