Interesting the Palo Alto Medical Foundation is now doing hip resurfacing.
A couple of years ago I listened to an presentation by Dr. Hartford about
hip replacements.  He dissed hip resurfacing by playing up the increase in
metal ions in the body after surgery.  Now, after a fellowship in Canada
where he learned hip resurfacing, he is offering the procedure.

I would have gone to him for hip replacement because he was not pushy and
had considerable experience (approximately 500 hip replacements but 0 hip
resurfacings).  I chose the Joint Replacement Institute in Los Angeles for
hip resurfacing versus replacement.  Dr. Amstutz had done over 2500 hip
resurfacing procedures when I went to him.   A year and a half later I am
fully satisified.
