Abstract

PURPOSE: Computer-assisted and robotic (CA/R) total hip arthroplasty (THA) has gained considerable attention due to its superior accuracy and precision. However, few studies have evaluated the public’s understanding and appraisal of this technology. Here, we evaluate the public’s initial perception of technology-assisted compared to traditional THA, and if interactive education may alter an individual’s preferences. MATERIALS & METHODS: A prospective cohort study was developed utilizing a 48-question, paid survey distributed via a clinically validated, public, online marketplace in April 2022. After collecting baseline demographics and knowledge regarding THA, participants were queried whether they would prefer a CA/R THA or traditional THA without additional information. Participants were then separated into “Tech” and “Traditional” THA cohorts. Respondents then completed an educational questionnaire which gathered respondent preferences while presenting evidence-based information regarding the surgical modalities. Upon completion of the educational questionnaire, cohorts were asked again which THA modality they would prefer. Statistical analyses were performed with Student’s t-tests and χ2 tests. RESULTS: Of 567 surveys, 507 surveys were completed with 311 (61.34%) Tech and 196 (38.66%) traditional THA respondents. Tech respondents took fewer daily prescription medications (1.07±1.83 vs. 1.48±2.41, p<.05). These respondents were also more likely to have heard of CA/R THA (45.02% vs. 28.57%; p<.001), but less likely to have any previous orthopedic surgery (12.22% vs. 22.45%, p<.05). All other demographics were similar between the cohorts. After completing the educational questionnaire, 95 (48.47%) of traditional and 267 (85.85%) of Tech THA respondents (total 71.40%) would choose CA/R THA if they needed a hip replacement now. Among this subset of individuals, 73.20% would switch surgeons for CA/R THA. With regards to cost, 88.27% traditional and 94.53% Tech respondents believed health insurance should cover the costs of CA/R THA (p<.05). However, the percentage of individuals willing to supplement their insurance costs was lower (40.51% Tech vs. 27.04% traditional, p<.01). Although significantly different, both groups in general indicated current surgeons should be trained for CA/R THA in its current state (aggregate 69.63%). Similarly, semi-active robotic THA would be preferable to fullyactive robotic and computer-assisted THA. CONCLUSION: Computer-assisted and robotic THA appears well regarded and valued by the public, with a sizable proportion willing to change surgeons in favor of those trained in this technology. Given this bias, it is recommended younger surgeons be familiar with this technology to accommodate the growing demand.
