Most DePuy reps are smart enough to know that ceramic on poly wears less than cobalt chrome on poly. Whether it has clinical significance is still up for debate. Some surgeon use ceramic heads for wear rate and some recently switched due to concerns over fretting.
Alot of DePuy reps and/or distributors have started working with Aesculap to provide an option for nickel allergy patients. I would rather us buy them than smith and nephew.
Aesculap ZrN multilayer coating on CoCrMo. This is not comparable to Oxinium in terms of its adhesion to the metal substrate. Oxinium's main weakness is the softness of the metal substrate. It will wear like hell if the ZrO surface is breached by scratches. I do not necessarily advocate Oxinium. But seriously, if Aesculap ZrN coated CoCrMo is the option you refer surgeons to, DePuy has painted itself into a corner regarding femur wear.
