This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether the NAVIO robotic-assisted system can perform knee replacement surgery as well as or better than the conventional surgical approach. The NAVIO system helps surgeons position and align the new knee joint with computer guidance, and researchers want to see if this leads to better outcomes, safety, and overall value for patients with severe knee arthritis.
Knee replacement surgery is common, but getting the new joint perfectly aligned during surgery is challenging and can affect how well patients recover. This trial exists to determine whether robotic assistance can improve the precision and results of knee replacement compared to the standard technique.

You will be randomly assigned to receive either robotic-assisted knee replacement or standard knee replacement surgery at Sint-Trudo Hospital. The study will track your recovery, pain levels, knee alignment, and overall function over time to compare how well each surgical approach works. You'll need to complete follow-up visits and possibly imaging scans to monitor your results.
