LEGION Hinge Knee System for Total Knee Replacement
(LINKS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effectiveness of a new knee device called the LEGION Hinge Knee System. It aims to assist individuals with serious knee issues, such as instability or failed knee replacements, by enhancing knee alignment and function. Suitable candidates include those with ongoing knee problems, like arthritis or previous unsuccessful knee surgeries. Participants must be prepared to adhere to the study protocol and attend follow-ups for five years post-surgery.
As a Phase 3 trial, this study represents the final step before FDA approval, providing participants an opportunity to contribute to a potentially groundbreaking treatment.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.
What prior data suggests that this hinged revision knee device is safe?
Research has shown that the LEGION Hinge Knee System has been used in various medical settings without higher risks. In one study, four patients received this knee system, and only one required additional surgery, though the reason was not specified. This suggests that most patients do well with the device.
The LEGION Hinge Knee System is designed for patients needing knee replacement due to severe instability or bone loss. Although it has been recalled before, such recalls are common as medical devices undergo continuous improvement. The device is used with bone cement, which helps maintain stability and security.
Overall, current evidence supports the safety of the LEGION Hinge Knee System for most patients. However, like any medical procedure, potential risks exist, and discussing these with a doctor is important.12345Why are researchers excited about this study treatment?
Researchers are excited about the LEGION Hinge Knee System because it offers a potentially groundbreaking approach to knee replacement surgery. Unlike traditional knee replacement options, which typically use fixed or rotating platform designs, the LEGION Hinge allows for greater flexibility and stability. This advanced design can be particularly beneficial for patients with severe knee instability or deformities. By enhancing movement and providing a more customized fit, the LEGION Hinge aims to improve patient outcomes and extend the lifespan of the knee implant.
What evidence suggests that the LEGION Hinge Knee System is effective for knee revision surgery?
Research has shown that the LEGION Hinge Knee System, which participants in this trial will receive, holds promise for those needing knee replacements. One study found that most patients felt satisfied or very satisfied with their new knee over time. Improvements have been observed in knee function and pain reduction. Another study reported that similar knee implants remained effective, with 100% still functioning at one and two years. These findings suggest that the devices are effective and durable for many patients.26789
