Hip implant showdown: which design leaks less metal?
NCT ID NCT03371212
First seen Jan 10, 2026 · Last updated Jun 22, 2026 · Updated 31 times
Summary
This study compares two types of hip replacement implants to see if one design leads to higher levels of metals like cobalt and chromium in the blood. Researchers will follow 52 adults receiving either a standard or a 'dual mobility' implant. The goal is to understand which implant is safer in terms of metal exposure.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
hip replacement implant (dual mobility vs. conventional)
What this could lead to
If it works, this could help surgeons choose safer hip implants that minimize metal release into the body.
What could go wrong
This is a small, early-stage study with only 52 participants. It measures metal levels, not long-term health effects, so the real-world impact is uncertain.
