@akrobertson Hello and welcome to Mayo Connect. It seems like when hip replacements go well they are wonderful,and when there are issues, suddenly the ortho surgeons all try to send you elsewhere. When my implants were failing 12 years ago, it was a chore to find good advice.

I don't know your age or the reason for the surgery, but looking forward to dealing with this for a lifetime is daunting. Also, with such a discrepancy, I expect you have significantly different leg lengths now, which can lead to gait and back problems.

Have you gotten a report from the original surgeon explaining why the wrong size femur implant was used? These come in many different brands, sizes and shapes, so it is hard to imagine using one that didn't fit. If you don't have them already, please request (or demand) all of your records from the surgeon, hospital and anyone else involved. There should be complete surgical reports in both the hospital's and surgeon's records, and you are entitled to them.
Once you have that in hand, would you consider a consult with Mayo or another highly rated ortho facility near you?
