it all depends on what part of the hip replacement fails. there are times when a revision hip replacement just entails a change out of the liner in the hip socket portion of the replacement. this is generally a pretty easy operation to recover from. there are also times when the femoral component (thigh bone implant) and/or the acetabular component (metal part of the hip socket implant) fail. these are bigger operations and are associated with a longer period of recovery. there is not doubt that surgeons now have much better implants to use in these "redo" situations. it is hopeful that the options for these redo procedures continue to improve as we go forward. it is most important to make sure you keep an appropriate follow-up schedule with your surgeon so that early signs of failure are not missed.
i'm 53 with two total hip replacements on my left leg. i expect one more hip replacement at 65. what will happen then?
