Two Year Study With Robotic-Arm Assisted Hip Surgery.

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Eligible Ages 18 Years and Over
Gender All

Trial Details

Trial ID:

This trial id was obtained from, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.

Arms & Interventions


No Intervention: Control

Traditional THA.

Active Comparator: Intervention

Robotic-arm assisted THA.


Procedure: - Robotic-Arm Assisted THA

The study will 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.
