What is the purpose of this trial?

This trial explores a new method for placing a hip component called the EMPHASYS cup during hip replacement surgery. The VELYS hip navigation system, a non-invasive tool, assists surgeons in positioning the cup more accurately. The trial aims to compare this new method's performance to traditional techniques. Suitable participants are those undergoing standard, uncemented hip replacement surgery using the EMPHASYS cup. As an unphased trial, it offers patients the chance to contribute to innovative surgical advancements.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, if you are taking prescription medications for a muscular disorder that limits mobility, you may not be eligible to participate.

What prior data suggests that this surgical navigation system is safe for hip replacement surgery?

Research has shown that the EMPHASYS™ hip 'cup' and the VELYS™ navigation system aim to enhance hip replacement surgeries. Although specific study details on safety are not provided, the EMPHASYS™ system belongs to a new generation of hip solutions, suggesting improvements in performance. When a treatment is in a "Not Applicable" phase in a trial, the focus typically shifts to its effectiveness or usage rather than basic safety, implying that initial safety assessments have been completed. Additionally, similar navigation systems have not extended surgery duration, indicating positive outcomes for both safety and efficiency. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the EMPHASYS Cup with VHN because it offers a non-invasive navigation system for treating osteoarthritis, which could enhance the precision of surgical interventions. Unlike traditional surgical procedures that rely heavily on the surgeon's experience and visual estimates, this system integrates advanced technology to guide the placement of implants more accurately. This could potentially improve outcomes, reduce recovery times, and lessen the risk of complications, making it a highly promising advancement over existing approaches like total knee replacements or hip arthroplasty.

What evidence suggests that this surgical navigation system is effective for osteoarthritis?

Research has shown that the EMPHASYS™ acetabular shell, used in this trial, can be accurately positioned with the VELYS™ hip navigation system. This non-invasive system requires no cuts or incisions and assists surgeons in placing the hip cup with greater precision. Accurate placement is crucial, as it can enhance joint movement and reduce pain for patients with osteoarthritis. Early findings suggest that this navigation system does not extend surgery time, which is beneficial. Overall, these tools aim to improve outcomes in hip replacement surgeries. ^{1 2 3 5 6}

Are You a Good Fit for This Trial?

This trial is for individuals with various hip conditions such as avascular necrosis, arthritis, osteoarthritis, ankylosis, developmental dysplasia of the hip, congenital hip dislocation, rheumatoid arthritis, and hip dysplasia who require a total hip replacement.
