EMPHASYS Cup Positioning in THA With Non-Invasive Navigation (Velys Hip Navigation (VHN))
What this study is about
The purpose of this research is to gather clinical and radiographic (X-ray) information about EMPHASYS™ acetabular shell (also called a hip 'cup') placement in total hip replacement surgery using a non-invasive surgical navigation system called VELYS™ hip navigation system with CUPTIMIZE™ Advanced Hip-Spine Analysis software.
View original scientific description
The purpose of this research is to gather clinical and radiographic (X-ray) information about EMPHASYS™ acetabular shell (also called a hip 'cup') placement in total hip replacement surgery using a non-invasive surgical navigation system called VELYS™ hip navigation system with CUPTIMIZE™ Advanced Hip-Spine Analysis software. Data collected in this study will be compared with data collected from implantations using different cup positioning instrumentation and techniques to assess performance.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- All hip replacement component devices are to be used according to the approved indications.
- The subject is undergoing a standard of care primary uncemented hip replacement with the EMPHASYS cup and a CORAIL, EMPHASYS or ACTIS stem via the posterolateral, anterolateral, or direct lateral approach with the subject in the lateral decubitus position.
- The subject is a candidate for implantation utilizing the VELYS Hip Navigation system with CUPTIMIZE advanced
- Individuals who are able to speak, read, and comprehend the Informed Participant Consent Document and willing and able to provide consent for participation in the study and have authorized the transfer of his/her information to DePuy Synthes.
- Individuals who are willing and able to complete follow-up as specified by the study protocol.
- Individuals who are willing and able to complete the Subject Hip Outcomes questionnaires (i.e., FJS-12, EQ-5D-5L and Hip Evaluation) as specified by the study protocol.
- Individuals who are not bedridden per the discretion of the investigator.
- Individuals who are a minimum age of 21 years at the time of consent
Exclusion criteria
- Active local or systemic infection.
- Loss of musculature, neuromuscular compromise or vascular deficiency in the affected limb rendering the procedure unjustified.
- Poor bone quality, such as osteoporosis, where, in the surgeon's opinion, there could be considerable migration of the prosthesis or a significant chance of fracture of the femoral shaft and/or the lack of adequate bone to support the implant(s).

- Subject has participated in a clinical investigation with an investigational product (drug or device) in the last three months.
- Contralateral hip was replaced less than 6 months prior to surgery date.
- Subject is currently involved in any personal injury litigation, medical-legal or worker's compensation claims.
- Subject was diagnosed and is taking prescription medications to treat a muscular disorder that limits mobility due to severe stiffness and pain such as fibromyalgia or polymyalgia.
- Subject has a medical condition with less than 2 years of life expectancy.
- Subject, in the opinion of the Investigator, is a drug or alcohol abuser or has a psychological disorder that could affect their ability to complete subject reported questionnaires or be compliant with follow-up requirements.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
