Patrick,
I would recommend you get a 2nd opinion to make sure that your implants are in a position that you do not have issues with too much wear. Metal ions could become an issue and sometimes it's warranted to get blood tests to check the function of your kidneys to make sure that you are ok.
You MUST think of your future not short term at this point, it's critical that you get on the right track to walking straight lines without any issues. Short term things like another surgery and some more rehab sometimes must be done to allow for long term solutions. Worrying about your decision to choose one doctor over another is not what you should concern yourself with....... even really experienced surgeons can have problems here and there, what's done is DONE. Nobody on this site will judge you on your decision we're here to offer our support.
Pick one of the doctors from Pat's list who has lots of experience and send them a digital picture of your x-rays and ask the doctor what they think, then think of your options.
Don't let this get you down, many people have had problems and ended up really good in the end, but you must at this point be your own best patient advocate.....what ever you do, fight to get your hip back to health.
Good luck
Chuck
