NAVIO® Robotics-Assisted Partial Knee Replacement
The Process Starts by Planning the Procedure with Your Unique Knee Anatomy in Mind.
Rather than a radiation-intensive CT-scan, the NAVIO system uses a bone surface mapping technique to collect information about your knee. The information collected is used to generate a 3D model, which your surgeon will use to virtually position the metal and plastic implant components that will replace your damaged knee. This is done prior to bone resurfacing so the surgeon can be sure the plan is right for you.
Once your surgery plan is finalized, your surgeon will use a robotics-assisted surgical tool (the NAVIO handpiece) to accurately remove the damaged surface of your knee. To complete the procedure, the implant components are positioned and the surgeon receives computer confirmation that your surgery was performed according to the plan.
Partial Knee Replacement with Traditional Techniques
Using traditional surgical methods, bone cutting guides are placed on the thigh bone (femur) and shin bone (tibia) to help direct a surgical saw in removing the diseased bone and cartilage. This method has been considered technically challenging, as accurately placing these guides can be difficult. Recently, advanced surgical techniques using robotic assistance like the NAVIO system have been developed to provide a higher level of precision and consistency.1
