NYU Langone Orthopedics' Dr. Vinay Aggarwal & Dr. Matthew Hepinstall discuss how joint replacement technology has evolved, why robotic systems became more useful over time, the latest advances in cutting-edge robotics technologies, and what patients should know about scans, cost, and safety.  Robotics can improve certain technical aspects of surgery, and robotic-assisted joint replacement is here to stay and will keep improving.
