On Robotic Surgery in Knee Arthroplasty: Beginning of a New Era

Abstract

During the past two decades, the use of robotic arms in knee arthroplasty has changed from a concept to a reality. These systems promise precision and accuracy while shortening the required learning curve. Although still largely in the early stages, there are currently several commercially available platforms with varying degrees of flexibility. The available models can be classified into several categories based on their mode of operation (whether the system requires imaging input) and degree of autonomy. The present study aimed to review the existing body of literature and provide an outlook of the current landscape. The strengths and weaknesses of the implementation of such systems in knee arthroplasty are also discussed.
