Computed tomography of the knee joint is taken before surgery. With the help of tomography, 3-dimensional model images of knee bone and joint structure are created. The model information is used in conjunction with the RIO software to plan the operation in accordance with the patient’s anatomy. This software provides real-time information that allows accurate positioning and alignment of the implant during surgery.
During surgery, the robotic arm provides the orthopedic surgeon with real-time visual and tactile feedback to the surgeon for optimal use of pre-made kinematic calculations of the joint prosthesis, while guiding the proper preparation and placement of the implant housing. When the surgeon performs the surgery, the robotic system prevents the surgeon from going out of planning and making mistakes.
Even an experienced orthopedic surgeon has some margin of error when manually adjusting implant positions. With the robotic system, the compatibility of the implants at all bending angles of the knee is evaluated kinematically during surgery.
Real-time adjustment can also be performed during surgery to ensure accurate knee kinematics and soft tissue balance. This minimizes the margin of error by ensuring that the surgical procedure is performed precisely and highly accurately, specifically to the patient’s own anatomy. This leads to a low risk of further unwanted complications (such as mechanical loosening and malposition).
In the robotic knee surgery procedure, only the knee ligaments are preserved during the removal of the deformed joint surface and bone structures, and a more natural knee feel can be achieved in the patients. In robotic knee surgery in Turkey, the high accuracy and precision of the technical measurements and the placement of the implant in the most ideal anatomical position for each patient contribute to less wear and loosening of the implant, contributing to prolonged prosthesis life.
