Robotic Knee Replacement

Robotic-assisted knee replacement is a knee replacement performed with the help of a robotic arm or guidance system. The surgeon stays in full control; the technology assists with planning and precise placement of the implant. It has become a common option at many hospitals and surgery centers.

What to expect

  • Performed under general or spinal anesthesia, like a conventional knee replacement.
  • A CT scan or computer mapping is often used before or during surgery to plan implant position.
  • Surgery typically takes about one to two hours; many patients go home the same day or after one night.
  • Walking with support usually begins the day of surgery, with physical therapy starting right away.
  • Recovery milestones are generally similar to conventional knee replacement, many daily activities by six to twelve weeks, with full recovery commonly taking up to a year.

Common questions

Is robotic knee replacement better than traditional knee replacement?
The robotic system helps the surgeon plan and position the implant precisely, and some studies suggest benefits in alignment. Research on long-term differences is still ongoing, so ask your surgeon why they recommend one approach over the other.
Does the robot perform the surgery?
No. The surgeon performs the entire operation. The robotic arm assists with guidance and precision but does not act on its own.
Is recovery faster after robotic knee replacement?
Recovery timelines are generally similar to conventional knee replacement. Your effort in physical therapy typically matters more to the result than the specific technique used.
