Summary

This study compares robotic-assisted total knee replacement to the standard manual procedure in 86 adults aged 40-85 with severe knee arthritis. Participants will receive the same knee implant, but one group's surgery is guided by a robotic system. Researchers will measure pain, stiffness, physical function, and mobility up to two years after surgery to see if the robotic approach leads to better outcomes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Robotic-assisted surgical system (Navio™)
What this could lead to: If successful, robotic-assisted knee replacement could lead to better implant placement, less pain, and faster recovery than conventional surgery.
What could go wrong: This is a small, early-stage study (86 people) comparing two surgical techniques. The robotic system may not improve outcomes significantly, and results may not apply to all patients.
