Although standard total hip arthroplasty (THA) techniques involving modern components yield excellent results in terms of overall survivorship and durability, hip instability and mechanical loosening are common causes for revision1. Navigation systems convert qualitative human judgments into calculated surgical decisions that are supported by patient-specific anatomical data, with the potential to improve the accuracy and reproducibility of implant positioning. Navigation refers to a tool that provides information about patient anatomy and the relative positioning of the implants to guide the surgeon. Robots are computerized instruments that carry out specific parts of the procedure on the basis of anatomical information that is provided to them.
