AB  - Background:Accurate implant orientation reduces wear and increases stability in arthroplasty. This is a technically demanding skill. Augmented Reality headsets overlay digital information over the real world. We have developed an enhanced AR headset capable of tracking bony anatomy in relation to an implant. Questions/Purposes:The purpose of this study was to validate this enhanced AR headset in the training simulator setting as determined by (1) quantitative assessments accurately orientating an acetabular component, and (2) a questionnaire regarding the realism of the task, acceptability ofthe technology, and its potential role for surgical training. Methods:Twenty-four novice surgeons voluntarily participated in a simulation trial. Demographics and baseline performance in orientating an acetabular implant to six patient-specific values on the phantom pelvis, were collected prior to training. All participants received standardised educational lectures based around four clinical vignettes on hip surgery to normalise their knowledge. Participants  were  randomised  to  two  groups,  completing  four,  once-weekly  sessions  of  baseline assessment, training, and re-assessment. One group trained using AR (with live holographic feedback of orientation), and the other received one-on-one tuition from an expert surgeon (ES). The solid-angle error in degrees between the planned and achieved orientations was measured. Participants completed baseline assessments, then training, and then assessment in this fashion after each weekly session, and a validated post-training questionnaire evaluating their experiences. Results:Novice surgeons of similar experience in both groups performed with a similar error prior to training (Baseline ES mean error 16° ± SD 7° compared to AR 14±7°, p>0.05). During training, participants achieved average errors in orientations of 1±1° using AR, and 6±4° when guided by the ES (p<0.001). At fin
