Stability of Revision Total Hip Arthroplasty Implants Using Radiostereometric Analysis
United States0Started 2012-02
Plain-language summary
The specific aim is to quantify the stability of the acetabular and femoral components of a revision total hip arthroplasty (THA) in vivo as currently performed at our institution. In this way, the investigators will gain insight into the outcome of the current state of the art of revision arthroplasty surgery. In the past, acetabular and femoral component stability has been measured using radiostereometric analysis (RSA) and when patients having revision total hip operations were compared to patients undergoing primary total hip operations it was possible to determine differences in stability and this was predictive of the intermediate to long-term performance of the acetabular and femoral reconstruction. The investigators propose to use this established, high resolution technique to assess and compare the stability of the revision implants.

Inclusion criteria
. Male or female.
. 25 to 75 years of age.
. Subjects requiring revision total hip replacement.
. Subjects who demonstrate the ability to return to MGH for follow-up for the next five years.
Exclusion criteria
. Subjects with limited life span.
. Subjects with difficulty in comprehending study protocol for any reason.
. Subjects with complex disease entities which significantly increase the risks of the surgery such as any major platelet abnormality, hematological disorder, or any other major medical complication which could substantially reduce longevity, put them at further risk due to immunocompromisation or increase the risk of infection.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
