Robotic-assisted total hip arthroplasty

Purpose: The aim of the review was to outline the evolution of navigation and robotic-assisted systems in total hip arthroplasty (THA), describe major classification schemes and current platforms, and summarize evidence on their clinical performance and limitations. Methods: This review traces the development of computer-assisted and robotic-assisted technologies in THA, highlights key system classifications and representative platforms, and synthesizes published data on accuracy, outcomes, and workflow considerations. Results: Navigation and robotic-assisted systems were developed to reduce variability in component placement through pre-operative planning, intra-operative guidance, and real-time feedback. Evidence demonstrates that robotic-assisted THA improves the accuracy of component orientation and limb length restoration compared with manual techniques, while long-term functional outcomes and cost effectiveness remain similar. Conclusions: Robotic-assisted THA provides measurable improvements in technical accuracy and reproducibility. However, further prospective studies with robust methodology are needed to clarify its long-term clinical and economic value.
