I am 57 and had a total hip revision almost 4 years ago. Have done great up until about 6 weeks ago and could feel "movement" when I moved my leg a certain way. Couldn't get an appointment with my surgeon until mid September so managed to see another surgeon. He xrayed and said it had loosened in the femur and was working up into the pelvic bone. He sent me back to my surgeon saying that he needed to fix it but told me to not go anywhere without my walker. My surgeon looked at the xrays and said "yeah it's worked loose and you have some bone loss but the top looks fine." He raised his eyebrows when I said the other doc had said I needed to use the walker. I asked "you raising your eyebrows does that mean you disagree?" His comment was "does it make you feel better?" as if I didn't really need the walker. He went ahead and scheduled surgery for Aug. 8th and said if I had too much bone loss he may have to "open up the femur and may need to use cadaver bone?" Of course this means a much longer recovery time. My worry is that he doesn't think the top needs to be replaced and that's fine if he's right but I can't keep repeating this surgery every few years.
