the current role of robotic-assisted total knee arthroplasty

Robotic-assisted total knee arthroplasty (ra-tka) improves the accuracy of component alignment compared with patient-specific instruments (psi) and conventional tka (c-tka), although clinically there is no difference between them in terms of postoperative outcomes. ra-tka still has significant limitations that advise against its widespread use, such as high installation costs, additional radiation exposure, a steep learning curve, the small number of implant designs that are compatible with robotic technology, the lack of long-term results and the large heterogeneity of available systems.
