Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals aged 18 to 75 suffering from conditions like hip arthrosis, dysplasia, or avascular necrosis who are suitable for total hip arthroplasty.

Probably not a fit

Patients with acute or chronic infections, severe bone deformation, or osteoporosis may not benefit from this study.

What this trial studies

This observational study focuses on the Mpact 3D metal cup used in total hip arthroplasty, particularly examining its effectiveness in achieving stable fixation without cement. The study aims to evaluate how factors such as patient age, bone quality, and specific conditions like osteonecrosis affect the long-term outcomes of the implant. By analyzing the initial stability and bone integration of the cup, the research seeks to identify improvements in clinical outcomes and reduce the risk of component loosening. Participants will be monitored for their recovery and overall satisfaction post-surgery.

Why it matters

Potential benefit: If successful, this study could lead to improved long-term outcomes and reduced revision rates for patients undergoing hip replacement surgery.

How similar studies have gone: Other studies have shown promising results with similar cementless fixation techniques, indicating potential for success in this approach.
