The knee joint is the point at which the femur bone of the thigh meets the tibia bone of the lower leg. All the components of the knee - bones, cartilage, synovial membrane, ligaments, tendons and muscles - must work together properly for the knee to move smoothly.
Cartilage is a protective cushioning that keeps the bones from rubbing against one another.
In a healthy knee, a thin, smooth tissue liner called the synovial membrane releases a fluid that lubricates the knee, reducing friction as the bones move.
Meet the NAVIO Surgical System, 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 is unique, based on your knee anatomy and the implant used. Designed to help ensure your knee replacement is positioned and aligned correctly, surgeons use the NAVIO Surgical System. Proper positioning of the implant is important because implant alignment is a crucial factor in determining how long your implant may last.
For people suffering from knee pain caused by osteoarthritis, whose damage is limited to a single compartment or area of the knee, partial knee replacement may be an option because it preserves healthy bone and ligaments while replacing the damaged area.The NAVIO Surgical System uses robotics-assisted technology to help tailor partial knee replacement procedures to the unique shape and motion of each patient's knee anatomy.
Other robotic knee replacement systems use computerized tomography, or CT, scans to help a surgeon visualize a patient's knee anatomy. While CT scans are effective at showing the layers of knee anatomy, they can expose the patient to potentially harmful radiation. In fact, a single CT scan is equivalent to the radiation exposure received in 48 chest X-rays.
The NAVIO system eliminates the need for CT scans by using an advanced computer program (similar to GPS navigation on your phone) to collect anatomic and alignment information about your knee. Once captured, this information is used to build an accurate, computer-rendered 3D model of your knee that your surgeon will use to plan your surgery.
More than 600,000 total knee replacement procedures are performed each year in the U.S. and more than 90% of these patients experience a dramatic relief in knee pain and are better able to perform common activities.1 The NAVIO Surgical System delivers robotics-assisted tools designed to help tailor your knee replacement surgery to the unique shape and motion of your knee.

Another method that can be used to determine the anatomic alignment of your new implants uses long, metal devices called intramedullary (IM) rods that are drilled into the central canal of the bone to show the alignment of the knee in relation to the hip. These rods are then used to attach the cutting guides necessary to guide the surgeon's saw blade as it shapes the bones to accept the new implants.
Because the NAVIO system has already gathered the anatomic alignment information about your knee, it eliminates the need for IM rods. Instead, your surgeon will use the system's handheld robotics-assisted tool (the NAVIO handpiece) to accurately position the NAVIO-specific cut guides which are held in place with a few small pins instead of the IM rod. This process leaves the central canal of your bone untouched. Implant alignment is a crucial factor in determining how long the implant will last
After removing the cutting guides, the prosthetic knee implants are implanted and your knee is checked to make sure it moves and is balanced correctly. It is important to understand that the NAVIO system doesn't replace your surgeon. The procedure remains in the skilled hands of your surgeon, with the NAVIO system providing extra layers of planning and accuracy.
Robotic Knee replacement Surgery technology is an innovative solution to conventional surgical methods for patients suffering from hip or knee joint pain.
The accurate alignment and positioning of joint implants is challenging in conventional hip and knee replacements. With the Robotic technology, our surgeons can now achieve greater precision.
Using a 3D image of each patient’s unique anatomy, the robotic technology helps guide the surgeon to stay within only the pre-determined area for greater accuracy in the positioning and alignment of the joint implant. The proper alignment of the implants results in quicker recovery times, more natural-feeling movement, and overall better outcomes for our patients.
If you suffer from severe joint pain and conservative treatments have not provided adequate relief, you may be a candidate for a hip or knee replacement with Robotic technology.
Many factors come into consideration when determining if a patient is a candidate. It is important that you consult with your orthopaedic surgeon to determine if the Robotic technology is the right option for you.
Total knee replacement: Adults living with mid to late-stage osteoarthritis of the knee may be candidates for a total knee replacement with the Robotic knee Assisted Surgery System. Mid to late-stage osteoarthritis indicates the disease has affected more than two of the knee compartments: Medial, patellofemoral, or lateral.
Partial knee replacement: You may be a good candidate for partial knee replacement with Robotic technology if you are an adult living with early to mid-stage osteoarthritis that has not yet progressed to all three compartments of the knee. Knee joint replacement is intended for use in individuals with joint disease resulting from degenerative, rheumatoid and post-traumatic arthritis, and for moderate deformity of the knee.
Joint replacement surgery is not appropriate for patients with certain types of infections, any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complications in postoperative care, compromised bone stock, skeletal immaturity, severe instability of the joint, or excessive body weight.
