Evolution of 3-Dimensional Functional Planning for Total Hip Arthroplasty with a Robotic Platform.

Abstract

Robotic-assisted surgery was introduced to make various mechanical aspects of a total hip arthroplasty more reproducible. When paired with sophisticated three-dimensional preoperative planning, robotic surgery offers the promise that a surgeon might select and reliably achieve targets for component position to optimize hip center-of-rotation, acetabular anteversion and inclination, femoral offset, as well as limb length. This paper describes a patient-specific step-by-step approach to performing these procedures including taking into account pelvic tilt. It is hoped that these described techniques will further optimize robotic-assisted hip arthroplasty procedures.
