This is one of the reasons I quit using the Oxford and switched to Mako. My Biomet rep was just as ignorant as you are. I have revised almost 30 Oxford uni's from surgeons around this area (including my own). The Oxford is all about marketing and you had me fooled for a short while. It is all about how you put the implant in and not what the implant is about. Yes I know your marketing people tell you different, but they are clueless.
