Robotic Knee Replacement

What is robotic-assisted surgery?

It is an exciting time in the field of joint replacement as we continue to implement new technology in an effort to improve patient outcomes. Robotic surgery involves some type of robotic arm that assists the surgeon with preparation of the bone. The surgeon still performs every step of the surgery using the robot as a tool.

What are the steps involved in robotic surgery?

First, metal pins are placed in the patients femur and tibia so the robot can understand where the leg is in space. Next the robotic system has to accurately register each patient’s unique anatomy. Some systems involve a CT scan prior to surgery, while others involve using a special instrument to outline the patient’s anatomy during surgery. After this registration process is complete and verified, the robotic arm is brought onto the surgical field. The robotic arm performs precise bone resection based on the input provided by the surgeon. Lastly, most systems also provide information regarding the stability of the knee as well as range of motion.

Who is a candidate for robotic surgery?

All patients are potential candidate for robotic-assisted surgery. Ideal candidates for this type of surgery include patients with previous surgery and hardware in place that makes standard instrumentation difficult, or severe deformity of the limb. Dr. Kelly will discuss all options with the patient and mutually make a decision that is best for each patient.

What are the benefits of robotic surgery?

Benefits of this surgery include increased precision and accuracy of bone cuts during knee replacement.

What are the risks of robotic surgery?

Unique risks of robotic surgery include complication at the pin sites (e.g., infection, fracture) that are not required in standard total knee replacement.
