Surgical robots can help fine-tune and improve accuracy of joint replacement.
With robot-assisted joint replacement surgery, the surgeon can accommodate for each person's unique anatomy. "During knee replacement surgery, we place markers in the thigh bone and the shin bone and then we map out the ends of the bones," says Dr. Molloy. The computer detects the markers and overlays a map of the knee joint over a computed tomography (CT) image that was taken before the surgery. The surgeon can then very accurately position the components of the implant.
