Robotic-Assisted Total Knee

Using the Zimmer Biomet ROSA robot, Dr. Sayeed performed the surgery, also known as robotic-assisted knee arthroplasty, on Oct. 17 at Methodist Main Hospital in the Medical Center.

“The surgery turned out fantastic,” Dr. Sayeed said. “We now hope to offer this surgery to all of my patients in need of a total knee replacement. This patient had severe knee arthritis from years of wear and tear. He had constant pain and wanted to return to being active. The patient failed all conservative treatments, such as physical therapy and steroid injections. The patient was an ideal candidate for knee replacement surgery,” Dr. Sayeed added.

During the robotic-assisted surgery, Dr. Sayeed is provided data by the robot regarding the balance of the ligaments, depth of bone resection, and angle of the bony cuts, he explained. “The robotic arm comes in and positions our cutting block based on the data we’ve collected and analyzed as we are performing the surgery.”

During ROSA robotic total knee replacement, surgeons use standard x-ray scans to build a virtual model of the patient’s knee. With that model as a guide, the surgeon then uses the robotic arm to cut the bone precisely which helps to position implants more reliably. “The difference with the ROSA robot is that my hand has control over the saw and not vice versa. The human is in control of the robot,” he said. “The goal of this surgery is that patients will have less pain, better function, and quicker recovery,” Dr. Sayeed said.

Dr. Sayeed, who completed his residency training at the Mayo Clinic in Rochester, Minnesota and fellowship in total joint surgery at the Rubin Institute for Advanced Orthopedics, trained with the ROSA Knee System in order to be certified to perform robotic-assisted total knee arthroplasty. Dr. Sayeed has a Master of Engineering degree with specialization in building miniature devices. With his engineering background, using the ROSA robot is a natural tool for him to perform total knee replacement surgery.
