OUTCOMES OF ROBOTIC-ASSISTED AND CONVENTIONAL HIP ARTHROPLASTY

The purpose of this study is to assess the accuracy of component positioning and incidence of peri-operative and 90-day post-operative complications following robotic arm-assisted and conventional total hip arthroplasty (THA). Three groups of patients were analyzed for this study: those that underwent conventional THA performed by Surgeon 1, conventional THA performed by Surgeon 2, or robotic arm-assisted THA performed by Surgeon 2. All patients underwent primary uncemented THA via a posterior approach. Patient characteristics, intra-operative data, and 90-day post-operative complications were collected. Post-operative standing pelvic radiographs were utilized to measure acetabular position and to identify post-operative complications. Acetabular component position measurements revealed substantially less variation in both inclination and anteversion in the Surgeon 2 – Robotic group. Nine patients had intra-operative cables placed for intra-operative calcar fracture in the Surgeon 1 group compared to one ...
