This trial is testing the ROSA Knee System, a robotic surgical assistant that helps surgeons perform knee replacement surgery. The study will measure whether the ROSA system can adjust the surgical plan during the operation based on what the surgeon discovers, and whether this approach improves how well the surgery works for patients. The trial will follow patients for up to 2 years after surgery to see how well their knee functions and how satisfied they are with the results.
Surgeons sometimes find that what they planned before surgery needs to change once they're in the operating room and can see the actual condition of the knee. This trial wants to confirm that the robotic system can help surgeons make these real-time adjustments safely and accurately, and that doing so leads to better outcomes for patients.

If you are selected, you will receive knee replacement surgery performed with the help of the ROSA robotic system. Before surgery, the surgeon will create a plan using imaging scans, but during the operation, the surgeon can adjust this plan based on what they find. After surgery, you will attend multiple follow-up visits over 2 years where doctors will assess how well your knee is working, ask about your pain and function, take X-rays, and evaluate your overall satisfaction with the results.
