I am not surprised by the refusal to do another hip surgery - in fact I am more surprised that we haven't heard from more people in your situation.

There are always reasons for implant failure - sometimes more than one. Most commonly it is MRSA, other bone infection, bad osteoporosis or a fracture after the implant.
My cousin has been without a joint for over 10 years - she had MRSA, and also is diabetic and overweight - no surgeon is willing to risk another surgery. Another friend had to find an ortho who specializes in dealing with complex joint implants after failure due to weak bones - it took 5 years for the 2 of them to agree it was the right time to try again - her results are marginal - still quite a bit of pain, and she will always walk with a cane. (Sorry, I can't provide his name - he has left the area, and I think retired.)

Sorry you are all suffering these difficulties. I suggest that if you believe the underlying cause of failure has been resolved, you seek a surgeon who specializes in complex cases. Mayo, your local University medical school or a teaching hospital is a good place to start looking.
