“With superior capsulotomy there is no fluoro or X-ray required, there is more accurate component placement, and it’s extensile,” argues Stephen Murphy. “And there is a 23% lower cost over 90 days.” Jose Rodriguez counters, “The major reason why this hasn’t spread is that you have to buy into navigation.

Why pay more for something that is not improved?”
