AB - Three-dimensional planning of hip arthroplasty is associated with better visualisation ofanatomical landmarks and enhanced mapping for preoperative implant sizing, which can lead to adecrease in surgical time and complications. Despite the advantages of hip resurfacing arthroplasty(HRA), it is considered a technically challenging procedure and associated with inaccurate implantplacement. This study aimed to examine the validity, reliability, and usability of preoperative 3DHip Planner software for HRA. Fifty random cases of various hip osteoarthritis severity wereplanned twice by two junior trainees using the 3D Hip Planner within a one-month interval. Outcome measures included femoral/cup implant size, stem-shaft angle, and cup inclination angle, andwere assessed by comparing outcomes from 2D and 3D planning. An adapted unified theory ofacceptance and use of technology (UTAUT) survey was used for software usability. Bland–Altmanplots between 3D and 2D planning for stem-shaft and inclination angles showed mean differencesof 0.7 and −0.6, respectively (r = 0.93, p < 0.001). Stem-shaft and inclination angles showed inter-raterreliability biases of around −2° and 3°, respectively. Chi-square and Pearson’s correlation for femoralimplant size showed a significant association between the two assessors (r = 0.91, p < 0.001). The 3Dtest–retest coefficient of repeatability for stem-shaft and inclination angles were around ±2° and ±3°,respectively, with a strong significant association for femoral implant size (r = 0.98, p < 0.001). Surveyanalyses showed that 70–90% agreed that 3D planning improved expectancy in four domains. 3Dhip planner appears to be valid and reliable in preoperative HRA and shows significant potential inoptimising the quality and accuracy of surgical planning.
