Gil Medical Center at Gachon University said it first introduced an AI-based robot for orthopedic surgery, NAVIO, in Korea, and successfully performed knee replacement surgery using the new technology.
Last Wednesday, a team led by Professor Sim Jae-ang from the Department of Orthopedics at Gil Medical Center performed joint replacement surgery using NAVIO on a person aged 70 and over who suffered from degenerative osteoarthritis. The operation was successful and the patient is recovering.
NAVIO is a robot equipped with the most advanced technologies, such as AI, machine learning, augmented reality (AR), anatomy and image fusion.
A patient undergoing robotic knee replacement surgery previously required computed tomography (CT) images. However, NAVIO has an “image-less platform,” which does not require separate CT images, the hospital said.
The Non-Image Platform is a system that provides physicians with 3D anatomical information based on the kinematic alignment of the patient. A separately installed UV camera interacts with more than 10 sensors to deeply analyze the doctor’s minute movements and lesions and provides real-time information with AR technology.
The accumulated information is then compared to the results of the pre-simulation, and the system tells physicians in real time if they are operating at the correct angle and size. On the monitor, the robot provides the required cutting area in four colors: purple for 3mm and above, blue for 2mm, green for 1mm, and white for the target area.
Surgeons can perform the operation that best suits the patient’s condition, and the robot avoids the risk of malfunction or damage to healthy tissue by correcting its position and direction itself.
During surgery, the robot provides a “bur cutting guide” for drilling holes with precision, a “distal bur technique” for cutting and robotic technology for cutting delicate areas.
“A good understanding and skill in artificial joint surgery by the surgeon should be a priority, but robotic joint surgery will significantly help physicians improve the accuracy of the surgery. This will be especially helpful for those who are performing knee replacement surgery for the first time, ”Sim said.
Robotic surgery, armed with advanced technologies, can reduce reoperations, improve patient satisfaction with rapid recovery, increase staff efficiency by reducing fatigue, and reduce patient complications, he added.
