This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is testing whether a newer robotic-assisted surgical system called Navio can improve outcomes in total knee replacement surgery compared to the conventional manual approach. Researchers want to know if the robot's precision leads to better pain relief, function, and long-term results in patients with severe knee arthritis. You would be randomly assigned to receive either the robot-assisted surgery or the standard surgery, and your recovery and outcomes would be carefully tracked over time.
Although conventional knee replacement surgery is the standard treatment and works well, some patients still experience misalignment of the new joint after surgery. Newer robotic systems have shown promise in achieving more precise surgical alignment, but doctors need solid evidence that this added precision actually translates into better outcomes for patients before widely adopting the technology.

If you enroll, you will be randomly assigned to either receive knee replacement surgery using the robot-assisted system or using the conventional surgical approach. You will not know which group you are in (this helps make the results more reliable). After your surgery, you will have follow-up visits where your doctors will assess your pain, function, and how well your new knee is working, including physical examinations and possibly imaging scans, over the recovery period.
