NCT01672320

Brief Summary

The objectives of this study are to evaluate the clinical value of robotic-assisted total hip arthroplasty with respect to acetabular cup implantation, and to document the long-term clinical outcome of patients with Total Hip Arthroplasty (THA). IRB approval will be obtained at every study site to evaluate the basic clinical outcomes and post-operative component placement accuracy of each MAKO® THA patient. The hypothesis is that robotic preparation of the acetabulum will significantly reduce the variability and inaccuracy in the component alignment parameters that lead to post-operative complications, including implant failure.

Eligibility Criteria

Age20 Years - 75 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Adults requiring a total hip arthroplasty procedure.

You may qualify if:

  • Male or female
  • to 75 years of age
  • Subjects requiring primary total hip replacement
  • Contralateral hip should be relatively free from arthritis for comparison purposes, specifically with less than a grade of 2 on the Kellgren-Lawrence Scale.
  • Subjects diagnosed with osteoarthritis or traumatic arthritis
  • Subjects with avascular necrosis
  • Subjects who demonstrate the ability to return for follow-up for the next 10 years

You may not qualify if:

  • Subjects with difficulty understanding protocol for any reason
  • Subjects with a limited life span
  • Subjects with inflammatory hip disease, previous joint infection, or those requiring hip revision surgery
  • Female subjects who are pregnant, or who plan to get pregnant while enrolled in the study
