In plain words

What the trial is, and whether it could suit you

Total knee replacement is a common surgery for patients with severe knee arthritis. To improve surgical accuracy, surgeons now use robotic systems to help plan and perform the procedure. A new robotic system called KUNWU® has been developed in Hong Kong. Unlike many other systems, it allows surgeons to choose from different brands of knee implants. This study is a randomized controlled trial. It will compare two different types of knee implants (Attune and Persona) used together with the KUNWU® robotic system. The main goal is to see how accurately the robotic system helps achieve the knee alignment that was planned before surgery. Alignment refers to the straightness and balance of the knee joint after the implant is placed. Participants will be adults with knee osteoarthritis who need a total knee replacement. They will be randomly assigned to receive either the Attune or Persona imp
