New hip liner tracked for 10 years: will it last?
NCT ID NCT07150221
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 52 people who already received a Vivacit-E hip liner during total hip replacement. Researchers will track how long the implant lasts and any problems over 10 years. The goal is to confirm the liner is safe and helps reduce pain and improve movement for conditions like arthritis or hip injury.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Vivacit-E Vitamin E highly crosslinked polyethylene elevated liner (a medical device used in hip replacement surgery)
- What this could lead to
- If successful, this study could confirm that the Vivacit-E liner is safe and works well for at least 10 years, helping people with hip pain move better.
- What could go wrong
- This is a small, observational study with only 52 people, so results may not apply to everyone. The device could still fail or cause complications over time.
