Is this trial a fit for you?

Likely a good fit

Adults (18+) undergoing elective primary total hip replacement who can give informed consent and will receive the approved ACE Acetabular Cup with a JRI femoral stem and head.

Probably not a fit

Patients treated for hip fracture/trauma, those who cannot consent or comply with follow‑up, pregnant patients, or those receiving non‑approved implant combinations are not eligible and would not benefit from this surveillance.

What this trial studies

This observational 10-year post-market surveillance follows adults who receive the CE‑marked ACE Acetabular Cup as part of an elective primary total hip replacement. Data are collected at intervals using patient-reported outcome questionnaires, review of X‑rays, and recording of complications and revisions. The device includes an H‑A.C. coating to promote bone integration and offers ceramic, polymer, or dual‑mobility liners to match surgeon preference. Patients must be able to consent and receive the approved implant combination, and exclusions include trauma cases, pregnancy, or inability to comply with follow-up.

Why it matters

Potential benefit: If successful, the study could confirm long‑term safety and function of the ACE cup and help surgeons and patients choose the best implant.

How similar studies have gone: Previous post‑market registries and studies of coated acetabular cups and dual‑mobility liners generally report good fixation and low revision rates, but device‑specific long‑term data remain important.
