A surgeon at the Hospital for Special Surgery in New York recently performed the first knee-replacement procedures in the US using augmented reality (AR), The Wall Street Journal reported.
The Medacta's NextAR platform, which received FDA approval for total knee replacements in 2020, was used for the two procedures.
Prior to a procedure, computed tomography knee scans of the patient are loaded into Medacta’s NextAR cloud-based platform, which creates 3-D models of the knee.
The surgeon used a pair of AR glasses, manufactured by Vuzix, which include a digital display in the lens that enabled him to view the patient's knee and the surgical planning parameters.
Meanwhile, two quarter-size sensors, which are placed above and below the knee joint, transmit a signal to the AR glasses with a precise measurement of their spatial position in 3-D.
