Reproducing the Hip Anatomy: Intraoperative Planning and Assistive Devices (CAS, Robotics)

Abstract

Total hip arthroplasty is a very successful procedure for treatment of osteoarthritis. However, there are still occurrences of complications such as early revisions, leg length inequalities, and altered biomechanics that can lead to patient dissatisfaction that may be attributable to suboptimal component placement. In this chapter, we present current developments related to the use of computer-assisted surgery planning, bone preparation and implanting, the use of robotics, and the combination of these factors for a personalized, patient-specific approach in hip arthroplasty with the goal to provide optimal care for each individual. We discuss several currently approved systems and the potential risks and benefits associated with each technology. We conclude with an outlook regarding the future of CAS and robotics in personalized hip arthroplasty.
