G’day; Just to tell you that I, like thousands of others, are
walking around with fist sized lumps of cobalt-chromium as artificial
knees, and many others have the same alloys in hips, etc. I have had
mine for about 7 years with no problems. I don’t think that cobalt ,
chromium, platinum, or titanium cause problems inside people.
There’s too much evidence to the contrary.
Cheers for now,
