Comparison of Robotic-assisted and Conventional Acetabular Cup Placement in THA: A Matched-pair Controlled Study

Abstract

Use of the robot allowed for improvement in placement of the cup in both safe zones, an important parameter that plays a significant role in long-term success of THA. However, whether the radiographic improvements we observed will translate into clinical benefits for patients-such as reductions in component impingement, acetabular wear, and prosthetic dislocations, or in terms of improved longevity-remains unproven.
