If you look in the literature joint replacements typically fail 1% to 2% per year. So if you look at joint replacement ten years out from surgery, typically 80% to 90% of them are in and still doing well and in twenty years 60% to 80% of them are in and still doing well. Typically when joint replacements fail they can fail for several reasons. One is you can wear the plastic liner in the socket much like you can wear tread on a tire. The implants can come loose from the bone, or you could fracture around the implant. Typically if these implants fail they can be redone and it’s typically a larger surgery with a harder recovery.
