Study Summary

This trial will compare two types of hip replacement technology to see which is more successful. One uses a Tritanium Acetabular Shell, and the other uses a similar technology. The study will last for five years.

Who is the study for?
This trial is for adults over 18 needing a primary cementless hip replacement due to non-inflammatory degenerative joint disease. Participants must be able to follow the study's procedures and visits. It excludes those with active infections, immune suppression, prior hip replacements or fusions, BMI ≥ 40, systemic diseases affecting bones, material sensitivities, or neuromuscular deficiencies.Check my eligibility
What is being tested?
The Tritanium® Acetabular Shell is being tested in patients undergoing total hip replacement. The study compares two types of bearing surfaces: one group receives the X3® polyethylene insert alone; another gets the MDMTM liner with an ADM/MDMTM X3® insert. Success rates will be measured against similar technologies.See study design
What are the potential side effects?
While specific side effects are not listed here, typical risks associated with hip replacement may include pain at the site of surgery, infection risk around the implant area, possible dislocation or loosening of implants over time.
