You deserve a knee replacement procedure personalized for your unique anatomy!
NextAR Knee leverages the latest advances in Augmented Reality to help specially trained surgeons accurately place the knee prostheses while respecting your unique anatomy.
Augmented Reality is a a computer-based technology providing virtual content in the working environment. This technology has been used for more than 30 years in cutting-edge fields such as aerospace and aviation.
How NextAR knee replacement surgery works
Before knee replacement surgery
Unlike traditional knee replacement procedures, your surgeon will define a personalized knee replacement plan for you.
You will undergo a CT Scan before your surgery to create a personalized 3D model of your knee, which allows your surgeon to choose the best knee prosthesis and positioning, to restore function and your individual anatomy.
Exercises before knee replacement surgery might better prepare the muscles and tendons of the knee, potentially speeding up your recovery.
It is important to understand that if an exercise causes you more knee pain, you should stop doing it. Do not begin any exercises before discussing a plan with your medical team.
During knee replacement surgery
The NextAR knee replacement surgical procedure follows the same steps of a traditional approach but with the support of advanced optical trackers (2) connected to your leg.
These trackers send real-time data on your knee anatomy to the NextAR Augmented Reality Glasses (1), “empowering" your surgeon's vision.
With this technology, your surgeon can make more informed decisions and personalize your knee replacement procedure by making precise adjustments to your unique knee anatomy, thereby enhancing the accuracy of your knee replacement surgical procedure.
It’s important to know that your surgeon has been specially trained and always has complete control of the surgical actions.
Throughout the surgery, your surgeon can better evaluate ligament stability using this unique technology.
"This aims to make the structures supporting your knee neither too tight nor too loose, allowing your knee to move comfortably and smoothly. NextAR Knee works in synergy with the GMK Sphere knee prosthesis.
After knee replacement surgery
The NextAR knee replacement may help you go back to your everyday life - minus the pain. Your knee replacement recovery timeline will vary depending on your surgeon's recommendations.
It is important to remember that your timeline is unique. Patients may remain in the hospital for 1 to 5 days, depending on their specific condition and knee anatomy. This is why it is important to listen to your surgeon’s recommendations rather than comparing your recovery to others.
Once you return home, your medical team will encourage you to use your new “knee” and recommend the continued use of proper medications. You may also begin doing knee rehabilitation exercises at this time. Typically, most people can resume normal routine activities within the first 3 to 6 weeks after their total knee replacement16.
Why NextAR knee replacement surgery?
During your knee replacement surgery, NextAR Knee provides your surgeon with useful real-time data on your unique knee anatomy, which streamlines the surgical workflow and may lead to greater precision.
NextAR Knee Augmented Reality guided surgery may enable the surgeon to perform a less traumatic knee replacement surgery, reduce the knee replacement recovery time, and possibly aid in a faster rehabilitation.

3D technology
Patient-matched
MyKnee patient-matched surgical instrument
MyKnee is one of the latest knee replacement technologies developed by Medacta. This technology features a 3D Printed surgical instrument that is tailored for you, allowing it to accurately fit your knee.
The MyKnee journey
You will have a 3D scan (CT or MRI) of your knee to obtain an image before your scheduled surgery date.
Medacta will create a 3D model of your knee joint and personalized surgical instruments.
Your surgeon will customize your MyKnee plan to match your anatomy and determine the position of your final knee implant.
Prior to knee replacement surgery, your surgeon will receive the 3D printed MyKnee instruments and the 3D bone models that are specific to your knee. These instruments will be used to perform your knee replacement surgery.
Why MyKnee replacement technology instead of conventional procedures?
Surgical instruments are used to prepare the bone for proper positioning of a knee prosthesis. In conventional knee replacement surgery, surgical instruments are the same for all patients.
This means the instrumentation must be adjusted by the surgeon during the procedure to achieve satisfactory positioning for each patient.
MyKnee is a knee replacement technology that uses personalized instruments designed for your unique anatomy. These instruments are made with innovative 3D printing technology, which offers a very accurate manufacturing process and the highest design flexibility to match your knee anatomy.
After analyzing a 3D images of your leg, Medacta’s engineers provide your surgeon with an instrument that is designed and manufactured specifically for your knee replacement and approved by your surgeon on the basis of computer-aided planning.
