Robotic-Assisted Acetabular Cup Placement in Severe Intrapelvic Acetabular Protrusio: A Case Report

We present a patient with a 30-year history of severe intrapelvic acetabular protrusio. As far as we know, this is the first case report on the use of robotic technology in total hip arthroplasty for severe acetabular protrusion. We also discuss the challenges and lessons learned from this technically demanding case.

Robotic assistance has its advantages in the accurate templating of the optimal cup dimensions, orientation, and location. However, the surgeon may still need to manually restore the offset because the center of rotation is not re-established and must be mindful of the severity and chronicity of the soft-tissue contractures.
