Imageless Robotic Knee Arthroplasty

Robotic-assisted total knee arthroplasty is increasing in prevalence and has been shown to enable improved accuracy in implant positioning in total knee arthroplasty (TKA). Robotic assisted TKA can be categorized into image-guided and imageless techniques. In image-guided robotic TKA systems, preoperative imaging, most frequently computed tomography, is used to map bony anatomical landmarks to preoperatively obtained image to plan bone resections and implant sizing and positioning. Imageless robotic-assisted TKA does not require preoperative advanced imaging and intraoperatively maps bony anatomy to guide bone resection and implant sizing and placement. The purpose of this article is to describe the surgical technique for imageless robotic-assisted TKA and to provide a concise review of literature regarding surgical outcomes.
