Testing a navigation system for more precise hip replacement cup placement

This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.

What is this trial?

This study is testing a new surgical navigation system called the VELYS Hip Navigation system with CUPTIMIZE software, which uses computer guidance to help surgeons position the EMPHASYS acetabular cup (the socket part of a hip replacement) more accurately during total hip replacement surgery. Researchers want to compare how precisely this new navigation system places the cup compared to traditional techniques, to see if it improves outcomes for people needing hip replacement due to arthritis or other hip conditions.

Even small errors in how hip replacement components are positioned can affect how well they work and how long they last. This trial exists to determine whether using computer-guided navigation during surgery can help surgeons place these components more precisely, potentially improving results and reducing complications.

Do you qualify?

You likely qualify if…

you are at least 21 years old
you need a primary (first-time) hip replacement and are candidates for this specific surgical approach
you are able to understand the study information and give informed consent
you are willing to complete follow-up visits and answer survey questions about your hip function
you are not bedridden and can participate in the study activities

You likely don't qualify if…

you have an active infection in your body or the surgical area
you have severe bone loss (osteoporosis) or poor bone quality that could make surgery risky
you are pregnant or breastfeeding
you have had a previous hip replacement on the same side or the other hip within 6 months
you have a serious medical condition expected to limit your lifespan to less than 2 years

What participation looks like

If you qualify, you would undergo hip replacement surgery using the VELYS navigation system with CUPTIMIZE software—your surgeon will use computer guidance to position your hip cup during the procedure. After surgery, you'll attend follow-up appointments where researchers will take X-rays and ask you to complete questionnaires about how well your hip is functioning and your quality of life, helping them compare the precision and outcomes of this new navigation approach.
