First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study compares a new hip implant cup (Trident II) to an older version to see if it stays just as stable in the bone after surgery. Researchers will track 87 patients aged 40-75 for up to 10 years using special X-rays to measure any implant movement. The goal is to ensure the new design provides reliable fixation and reduces the risk of loosening over time.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Trident® II Clusterhole HA Acetabular Shell (hip implant device)
What this could lead to: If successful, this could confirm that the new implant is as stable as the current one, potentially offering a reliable option for hip replacement patients.
What could go wrong: This is a small, single-center study comparing two similar devices, so results may not apply to all patients or implants. The study only measures early stability, not long-term success.
