EMPHASYS Cup Positioning in Total Hip Replacement

This study is looking at how well a specific hip replacement component, the EMPHASYS™ acetabular shell (hip 'cup'), is positioned during total hip replacement surgery. Doctors will use a non-invasive navigation system called VELYS™ to help with placement. This research aims to collect information from X-rays and clinical assessments to see how successful the cup positioning is at 6 weeks after surgery. You may be able to join if you are an adult (21 years or older) needing a primary uncemented hip replacement due to conditions like osteoarthritis or avascular necrosis. The study is comparing this navigation system to other methods to understand its performance.

Study design
This is an interventional study planning to enroll 118 participants. It will compare data from hip replacements using the EMPHASYS Cup with VHN to other techniques.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up

What this trial measures

  • Composite endpoint: Acetabular Cup Position Success at 6 Weeks6 Weeks

    For an individual cup position to be considered successful, the cup's placement must satisfy all of the following criteria at 6 weeks: Inclination Success: within 10 degrees of the planned inclination via the surgeon-defined preoperative plan and version Success: within 10 degrees of the planned version via the surgeon-defined preoperative plan.
