Which hip stem lasts longer? new study compares two implants
NCT ID NCT03577522
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compared two types of hip implant stems (Avenir and Corail) in 56 people with hip osteoarthritis who needed a hip replacement. Researchers used special X-ray techniques to measure how well the implants stayed in place over two years. The goal was to see if the newer Avenir stem works as well as or better than the older Corail stem.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Avenir cementless hip stem and Corail HA-coated hip stem
- What this could lead to
- If one stem proves better, it could improve hip replacement outcomes and implant longevity for osteoarthritis patients.
- What could go wrong
- This is a small, completed study with only 56 participants, so results may not apply to everyone. Both stems are already in use, so no breakthrough is expected.
