What you're going to find if you dig deep enough is that when a surgeon who does not have experience doing HRs you will find misaligned devices that can lead to many issues. One is the metal ion issue. If the surgeon does not get the angles correct the two parts of the device will not work smoothly and you end up with ions of the metal being shed, you then end up with pseudotumors.
I know of doctors who NEVER had issues with the ASR because they got the angles exactly right, the ASR has a tolerance issue whereby the surgeon must get the angle within a closer tolerance than other devices.
Once again this is why those of us who have seen the many issues from inexperienced surgeons always say it over and over, find yourself a doctor with lots of years and surgeries behind him/her. Yes, you might feel good right after the surgery only to find out down the road a few years pain from inflamation and the resulting revision to a total hip.
Is there an issue with metal ions from metal on metal implants, heck yes! Will you have an issue on a properly implanted device, probably not.
Once again everyone, if you are searching for a doctor to do your HR, look for experience and a good record, not just 100 surgeries over a few years, go for the most experienced doctor you can find.
One question you can ask your surgeon, ask him/her what they consider to be the optimal angle of the implant they use and ask them how many implants they placed incorrectly, if they give you the deer in the headlight stare, run, don't walk out.

While BHR and Smith & Nephew, Inc. are not implicated, The New York Times article gave me pause. Does anyone have more information about the devices mentioned in the article? Is there cause for concern?
