More than 600,000 total knee replacement procedures are performed each year in the United States, and more than 90% of these patients experience a dramatic relief in knee pain and are better able to perform everyday activities.  OrthoNeuro offers partial and total knee replacement through robotic assistance using the Navio® Surgical System. The system works in conjunction with the surgeon’s skilled hands to achieve precise positioning of the components during surgery. This level of accuracy can help improve the function, feel, and potential longevity of the knee implant.

CT-Free Robotic-Assisted Partial Knee Replacement Surgery

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.1, 2  The Navio® Surgical System uses robotic-assisted technology to help tailor partial knee replacement procedures to the unique shape and motion of each patient’s knee anatomy.

Replacing only part of a knee joint can be more challenging than replacing the entire joint because the partial knee replacement must achieve an exact balance between the new implant – made of metal and plastic components – and the remaining portions of your natural anatomy made of bone and cartilage. As a result, one of the primary challenges of all partial knee replacements is precisely positioning the implant for each unique patient. Even minor changes in an implant’s size or placement can cause the knee to function poorly or result in early failure of the implant and the need for future surgery. The Navio® Surgical System addresses this challenge of a partial knee replacement by using both computer and robotic assistance to accurately map the surface of your knee, align your implant to your anatomy, and physically remove the bone necessary to place your new implant.This added level of assistance is essential because implant alignment is a crucial factor in determining how long the implant will last. 5, 6

CT-Free Robotic-Assisted Total Knee Replacement Surgery

The total knee replacement procedure starts with your unique anatomy in mind. By the time your procedure is complete, the damaged bones and cartilage within your knee joint will be removed and replaced with new implant components. Each of these implant components must fit precisely and be aligned to your natural anatomy if they are to provide you with the best outcome possible. The challenge of aligning your implant and preparing your bones to accept it can be complex, invasive and time-consuming because no two knee joints are exactly the same. The Navio®  Surgical System is designed to help your surgeon not only plan your surgery based on your unique anatomy but also position your total knee implant using a combination of computer and robotic assistance. The Navio® procedure starts with an advanced computer system that gathers precise anatomic and alignment information about your joint that your surgeon will use to create your specific surgical plan. This extra layer of data collection and planning is designed to help ensure your knee procedure is performed exactly as your surgeon intends and that your implant is positioned as accurately as possible for the best long-term outcome.

Individual results may vary. There are risks associated with any surgical procedure including Navio®-enabled Knee Replacement. Navio® is not for everyone. Children, pregnant women, patients who have mental or neuromuscular disorders that do not allow control of the knee joint, morbidly obese patients, or any other patients contraindicated for UKR, PFA, or TKA should not undergo a Navio® procedure. Consult your physician for details to determine if Navio® is right for you.
