CORI Surgical System
CORI is a robotics-assisted knee surgery platform that adds an extra layer of pre-surgical planning and improved accuracy for partial and total knee replacement procedures.
Your knee replacement surgery thus becomes unique, based on your knee anatomy and the implant used. CORI is designed to help ensure your knee replacement is positioned and aligned correctly as that is a crucial factor in determining how long your implant may last.
The latest innovation in knee replacement surgery
Surgical techniques have evolved considerably since the earliest knee implant procedures were performed in 1968. These procedures relied on manual guides, external pins and cutting jigs to remove damaged bone and place the prosthetic implant.
Eventually more advanced implant positioning techniques were introduced that used long rods drilled into the central canal of the femur (thigh bone). These rods provide an attachment point for surgical cutting guides. More recent improvements introduced CT scan/MRI image guidance to create an individualized computer-generated surgical plan for each patient.
The latest innovation is the CORI Surgical System, a robotics-assisted platform that uses CT-free technology for accurate implant sizing and positioning without the need for rods. The CORI Surgical System can be used for either a partial or total knee replacement procedure.
CORI system benefits: Accuracy, less exposure to CT radiation
The CORI system offers two important benefits for people undergoing a knee replacement procedure. First, it helps your surgeon create a highly individualised plan that is specific to the unique shape and motion of your knee. Traditional planning may require CT scans, a series of images similar to x-rays that shows cross-sections of your knee. While other robotic-assisted platforms require CT scans, the CORI system works without them, meaning you are not exposed to the potentially harmful radiation experienced with this type of imaging. The second benefit is Robotics assistance in execution of there surgery. This combination of advanced technology is designed to help your surgeon and may result in more accuracy, giving you better long-term outcomes.
The CORI system is used for both partial and total knee replacement, which are distinctly different procedures. Here's a bit more information on how the NAVIO system is used in these surgeries:
Partial Knee Replacement/Resurfacing
In total knee replacement surgery, the entire knee joint is replaced with a prosthetic implant designed to replicate the shape, motion and stability of your natural knee joint. Total knee replacement is one of the most common procedures performed in all of medicine. Ninety percent of people who receive a total knee replacement experience a dramatic decrease in knee pain, and an improvement in their ability to perform daily activities.
Robotics-assisted planning and Partial/Total Knee Resurfacing
Using the CORI system, we create a 3D representation of the unique shape and profile of your knee without the need of a pre-operative CT scan. Using this information we can then determine the correct size and position of the implant. Implant size and position is critical to knee alignment and stability. Next, we use robotics assistance of CORI to physically remove only the damaged bone and cartilage, preparing the site for the prosthesis, before placing and adjusting your final knee implant.
