What this trial studies

This observational study focuses on patients undergoing total hip arthroplasty who will receive the Mpact 3D Metal MonoCER cup. It aims to evaluate the long-term performance of this innovative cup design over a period of 10 years, with follow-up visits scheduled at 6 months, 1 year, 5 years, and 10 years post-surgery. The study will include patients under 75 years old who consent to participate, ensuring they receive standard treatment regardless of their participation. The goal is to gather data on the effectiveness and durability of the cup in real-world settings.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term effectiveness of the MONOCER Cup, potentially improving outcomes for patients undergoing hip replacement surgery.

How similar studies have gone: While there have been studies on hip arthroplasty, this specific observational approach to assess the MONOCER Cup's long-term performance is relatively novel.
