 A robotic assisted knee replacement is a procedure where a computer and a robotic arm are utilized to resurface a knee damaged by arthritis. Pre procedure, you undergo a CT scan to help the doctors plan exactly how much bone should be removed and optimize the placement of the implant. On the day of the procedure, you are administered anesthesia after which the surgeon makes an incision and uses a robotic arm to replace the damaged part of the knee with metal and polyethylene artificial implants. The implants mimic the natural knee movement and help you get back the range of motion and reduce knee pain. During the surgery, real time video images provide visual reinforcement which helps surgeons navigate hard to see areas. Before closing the incision, the surgeon rotates your knee, testing it to ensure proper function. The entire procedure takes about 2 hours. Post surgery, you may remain in the hospital for 2-3 days to ensure optimum recovery.
