Possible future ceramic resurface

There is always some talk about the possibility of a resurfacing that does not use metal. Here is a news release about some development work that is being done in Europe.
Sounds interesting, but it is still in the prototype stage, so there will not be any kind of a meaningful track record for many years.

Very interesting good find Jon, but as you say it wont have any sort of track record for a very long time. I like the fact they mentioned most of the issues were down to a poor device and poor positioning of devices. The ceramic and other materials out there though dont have some of the great qualitys that MOM does like its unbreakable nature and its self polishing. I think that they will have a long way to go to improve on the well designed devices out there.

I think I read somwhere they are working on a Oxinium hip resurfacing device too. Both are a few years off from being approved I would have thought and like you say 10's of years before they are actually qualified by which time Stem cell will probably be emerging to regrow cartilage.

Stem cells will be great for some people but they won't solve the underlying issues like FAI or bone spurs or cysts

Interesting story.  Thanks John

I recall Pritchett mentioning being involved with a study on ceramic on polyurethane but that it would be several years before there is even a hint of FDA acceptance.

Due to our sensitivity to the whole MoM issue, I should point out that USEPA and ATSDR both do not say that Co or Cr3 is carcinogenic.  However, some Co compounds and Cr6 (hexavalent) are carcinogenic.  Ionic Co and Cr (likely Cr3) will certainly react with various compounds within the body, but I have seen any evidence that suggests that there is carcinogenicity from MoM HR.
 
Understandably competition will drive the market, which is a good thing, but sadly the arguments are sometimes not quite accurate.
