Perceptions of robot-assisted arthroplasty among patients and the public : a scoping review

The use of robotic-assisted surgery (RAS) in total hip and knee arthroplasty is increasing, offering potential benefits in implant positioning accuracy. However, patient and public perceptions, including concerns and preferences, remain poorly understood. This scoping review aimed to explore the literature on patient and public perceptions of RAS in orthopaedics, identify common themes, assess knowledge gaps, and inform future research priorities.

A five-stage scoping review was undertaken according to the PRISMA extension for Scoping Reviews. Searches were performed across PubMed, Directory of Open Access Journals, Scopus, and ProQuest Central; Google Scholar and reference lists were also searched. Articles were collated and evaluated against predetermined criteria. Data from included studies were collated to facilitate descriptive and thematic analysis.

A total of 16 studies were included, primarily cross-sectional surveys. Four major themes were identified: interest in RAS; understanding regarding RAS; concerns regarding RAS; and influences on preferences and perception. Patients often overestimated the prevalence of use and the benefits of RAS, and based their preferences on marketing or limited information. Trust in surgeons remained a strong influence on patient attitudes.

Despite growing patient enthusiasm for RAS, significant gaps in public understanding and perception persist. Many patients held inaccurate beliefs about RAS capabilities and benefits. Future research should focus on creating validated educational tools for patients about RAS, expanding studies across diverse populations, and clarifying the value of RAS. Aligning public perception with clinical and non-clinical evidence is essential for informed consent and ethical surgical innovation.
