Haptic robotics enable a systems approach to design of a minimally invasive modular knee arthroplasty.

Novel arthroplasty tools present opportunities for exploring new implant designs, and such is the case for surgeon-guided or haptic robotic technology. These systems allow surgeons to sculpt bone precisely with or without direct visualization of the surgical site. It is in this context that we explored a novel system of implant components for modular knee arthroplasty intended to maximize the benefits of the robotic tools. In this article, we present the constraints, data, and decisions made to produce a version of a system of implant components for robot-assisted modular knee arthroplasty of the cruciate-intact knee.
