Augmented Reality Navigation
for Total Knee Arthroplasty
Knee⁺ is an innovative augmented reality solution designed to assist orthopedic surgeons during total knee arthroplasty procedures.
By providing real-time navigation of angular values and resection levels, Knee⁺ helps surgeons to achieve the expected cut orientation accurately(1,2).
Knee⁺ is a patented platform designed to help orthopedic surgeons performing surgery through the real-time 3D positioning of instruments, right in their field of view.
Knee⁺ is intuitive and consists of using a unique proprietary tracking system running
on off-the-shelf smart glasses, with no bulky capital equipment or disposables required.
The proprietary tracking technology in Knee⁺ provides angular measurements with accuracy of one degree and distance measurements with an accuracy
of one millimeter.
Knee⁺ helps surgeons achieve the intended orientation of the cuts with accuracy by providing real-time navigation of angular values and resection levels.
The system displays the theoretical HKA (Hip-Knee-Ankle) alignment,
which is crucial in assessing the alignment of the lower extremities
and optimizing surgical outcomes.
At the end of the surgery, the surgical report is automatically sent to the registered e-mail address.
