I just thought I'd chime in and mention that I had an HR done by a doctor who didn't have the necessary experience and skills to the do the job and it turned out to be a mess. After a hard year and a half I had a revision to a THR done by one of the world's best revison surgeons and, well, it's working out pretty dang awesome. A couple of years latter I had an HR done on my other hip by one of the world's top HR surgeons, someone who has good success with thousands of surgeries done and, well, the result so far has been pretty dang awesome.
So that makes me curious who your surgeons were, because I've developed a sort of theory (a theory overwhelmingly backed by the evidence I've seen so far) that goes like this: HR is a good alternative only when it is done by a committed specialist who has done hundreds (or better yet: thousands) of successful procedures. It seems to me there were a number of surgeons who "dabbled" in HR with out really committing themselves to developing the necessary skills and experience and when the results turned out poorly for them, the easy way out was to blame the procedure. Anyways, it's a theory I have.
Good luck Tom (and Tom) with your problems. My only advice would be, if you need a revision: search out and find a surgeon who has had good success performing (at least) hundreds of revision surgeries and someone who, based on their experience, can give you a high probability you will get your life back.

Tim (happy and rock climbing actively with revision surgery)
