Abrazo Arrowhead Campus in Glendale is adding to its operating room technology with the introduction of the CORI Surgical System for partial and total knee replacement.
The robot-assisted surgical system uses artificial intelligence that helps surgeons accurately size and place implants. A hand-held instrument uses computer guidance that enables physicians to sculpt the patient’s knee to receive the implant.
The AI-aided surgery system represents a new generation of robotic-assisted procedures, noted Abrazo Arrowhead CEO Stephen Garner. It offers another option for those seeking relief from arthritic knee pain.
“The procedure is suitable for most patients who are healthy, normally active and have arthritis of the knee,” Dr. Brent Hansen, an orthopedic surgeon at Abrazo Arrowhead Campus, at 18701 N. 67th Ave., shared in a news release. “Also, the Anterior Cruciate Ligament (ACL) is normally removed with most total knee replacements. With the aid of CORI, we can more precisely preserve the ACL (when intact) in healthy and active individuals. This can help the patient’s new knee feel more natural.”
The new robot is designed to help surgeons provide accuracy in bone resection and alignment through intraoperative planning, smart mapping and full range-of-motion data. The technology provides real-time data analysis to accurately predict how the knee is going to perform after the joint replacement procedure.
“The artificial intelligence platform allows the surgeon to take the knee through its entire range of motion before the new joint is implanted,” Hansen stated. “We are able to make adjustments in the implant positions in order to get a desired outcome.”
He stressed that the system is surgeon-controlled. The robotics are assisting through precise programming of the patient’s anatomy into the computer-guided system, which also contributes to ligament-sparing during the procedure.
Surgeons can visualize and individualize preparation for the joint replacement for each patient, using techniques that help minimize ligament disruption. When the procedure is complete, surgeons can then assess the initial outcome of leg alignment and knee balance.
Most robotic-assisted surgeries allow minimally invasive techniques. In orthopedics, this could include less violation of bone or sparing ligaments, often allowing faster recovery.
Robotics adds precision and accuracy to the surgeon’s movements.
