Robotic-assisted total hip arthroplasty

Abstract

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.
