Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Subjects enrolled will have already undergone a total hip arthroplasty with either a metal-on-metal articulation, or a ceramic-on-metal articulation.

You may qualify if:

  • Subject is 40 - 80, who has undergone a top hip arthroplasty with either metal on metal or ceramic on metal articulation for a diagnosis of non-inflammatory degenerative joint disease. We will also include subjects who have had bilateral hip arthroplasties or a second arthroplasty performed since the initial surgery.
  • Patient must be able to provide consent to participate

You may not qualify if:

  • Diagnosis other than non-inflammatory degenerative joint disease, chronic renal insufficiency, or any systemic inflammatory condition
  • Evidence of active infections
  • Patients whose occupations include welding or metal working
  • A second arthroplasty performed since the initial will not be exclude, but their data will be analyzed as a subpopulation
  • unwillingness to comply with rehabilitation program or inability to return for follow-up visits
  • Any systemic steroid therapy within 3 months of surgery
  • Subjects who are pregnant
