This observational study is looking at how different types of polyethylene (a plastic material used in hip replacements) wear down over time. Researchers want to compare a newer material, polyethylene containing Vitamin E, to older types of polyethylene to see if it reduces wear. They will do this by analyzing tissue samples collected during revision hip surgery (when a hip replacement needs to be redone). You might be able to join if you are over 20, need revision hip surgery, and had your first hip replacement at least two years ago. The study aims to find out if the newer material creates fewer or smaller wear particles, which could lead to better long-term outcomes for patients. The current recruitment status is unclear.

Study design

This is an observational study planning to enroll 90 participants. It compares three groups of patients who have had different types of polyethylene in their initial hip replacement.

What's involved

If you participate, tissue samples will be collected during your revision hip arthroplasty (surgery to replace a worn-out hip implant). This tissue is usually discarded during surgery.

Compensation

Not stated in the trial record.

Follow-up

The study measures outcomes when the tissue sample is collected during revision surgery, so there is no specified follow-up period after that.
