Tiger- PEEK does have excellent bearing qualities. Eliminates the concerns with cobalt ions. PEEK has traditionally been an expensive material compared to cobalt-chrome. But there may be two things going it its favor. One it can be injection molded. And secondly that cost of cobalt will be increases do to the utilization in many of the battery designs of electric vehicles.
But may have to re-think designs for cementless use as the porous surfaces I have seen in the past did not pose the surface roughness, to assist with fixation. Secondly, I do not recall if the interaction with PMMA is favorable or not.
From a regulatory stand point, will it require an IDE/PMA of can one get it through with a heavy weight 510k. The changes in the EU will also be an more difficult than traditional materials
