Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are 55–80 years old, planned for primary total hip arthroplasty with a dual-mobility cup, and able to consent and comply with follow-up.
✕Probably not a fit
Patients who are older than 80, have ASA 4, or are enrolled in conflicting studies may not benefit.

What this trial studies
This interventional study compares two dual-mobility acetabular cups, ECIMA CORIN and CORIN, in adults undergoing primary total hip arthroplasty. Eligible participants are 55–80 years old, plan primary hip replacement with a dual-mobility cup, and have access to French healthcare. The study aims to observe wear characteristics and related outcomes of the two implants over time. Participants will receive one of the two cup systems as part of their standard surgical care, with follow-up assessments to evaluate wear, function, and safety. The study is conducted at a single center in Lyon, France, led by GCS Ramsay Santé pour l'Enseignement et la Recherche.
Why it matters
Potential benefit: If successful, the better-wearing cup could lead to fewer revisions and longer-lasting hip replacements for patients.
How similar studies have gone: Wear performance comparisons between dual-mobility cups have been explored, with mixed results, making this direct comparison informative but not completely novel.
