Augmented Reality Used in Knee-Replacement Surgery in a U.S. First - (The Wall Street Journal via NewsPoints Desk)

  • 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.
