Augmented Reality in Orthopedic Practice and Education.

Augmented reality (AR) technology enhances a user's perception through the superimposition of digital information on physical images while still allowing for interaction with the physical world. The tracking, data processing, and display technology of traditional computer-assisted surgery (CAS) navigation have the potential to be consolidated to an AR headset equipped with high-fidelity cameras, microcomputers, and optical see-through lenses that create digital holographic images. This article evaluates AR applications specific to total knee arthroplasty, total hip arthroplasty, and the opportunities for AR to enhance arthroplasty education and professional development.
