The Orthopedic Surgery and Traumatology Service of the Francesc de Borja University Hospital in Gandia has incorporated new technology for artificial knee surgery.
It is a navigation system that allows computer-assisted surgery, which is an aid tool for the specialist during the implantation of a prosthesis. This allows for greater accuracy in the procedure, and, consequently, greater safety for the patient.
The technique consists of placing sensors on the femur and tibia that emit signals collected by an optoelectronic camera. With the collected information, the computer system develops a virtual image in two aspects: what the current position of the foot is like and what it should look like after the intervention.
The computer captures all the anatomical points needed for the correct alignment of the implant and represents them in three dimensions. The patient’s anatomy is shown in a completely personalized way, reflecting the most appropriate size of implants and their exact position.
All this information is displayed on the screen, so that the surgeon knows at all times whether the intervention is taking place within the established parameters.
As explained by the Head of Orthopedic Surgery and Traumatology Service at Gandia Hospital, Damien Mifsut, this is a system “particularly useful in knees with major deformities or when there is already implanted osteosynthesis material that cannot be compared with conventional techniques.” Stops the device with”.
In addition, the system includes a device called ‘Balancebot’ which allows to know the ligamentous tension of the knee across the full range of motion. This prevents the prosthesis from becoming too compressed or too loose and unstable.
“It is also essential to know the condition of the soft tissues by means of this device, as we find ourselves with very worn knees with too many changes in the axis of the foot, which changes the tension of the lateral ligaments”, The doctor said. Mifsut.
