Two Year Study With Robotic-Arm Assisted Hip Surgery.

Surgery Clinical Trial

Official title: A Two Year Multicenter Study of Robotic-Arm Assisted THA: Acetabular Cup Placement Accuracy and Clinical Outcomes

Status Completed

Clinical Trial Summary

This study will involve a quantitative assessment of prospectively collected computed tomography, radiographic and patient outcomes data from multiple centers. Specifically looking at acetabular cup placement during Total Hip Arthroplasty by either traditional or robotic-arm assisted placement.

Clinical Trial Description

The incidence of dislocation following total hip arthroplasty (THA) has been reported to be from 1% to as much as 3.2%. The demand for THA is expected to increase. Post- dislocation solutions include closed reduction, open reduction, THA revision, and constrained cup, conversion to hemiarthroplasty, allograft or girdlestone resection. These solutions are often costly, painful and can involve substantial additional risks and complications. Acetabular cup placement is an important factor in the stability of the THA. Cup malpositioning has been associated with bearing surface ware and dislocation. For most patients, acceptable angles for abduction are 40° abduction (±10°) and 20° (±5°) version. However, malpositioning continues to occur resulting in cup angles outside acceptable ranges and leaving patients with an increased risk of dislocation.

This objective of this study is to examine the acetabular cup placement of THA patients and compare results for patients who undergo THA with robotic-arm assistance with those who undergo traditional THA. ;
