He put them in because there was no joint left....now might be taking them out. If there's no joint left, won't that mean a lifetime of pain too?
(If it were me, I'd be getting a second opinion before deciding to have them taken out...we have so many medical people making such disturbing diagnoses'/remedies around here lately, that none of them can be trusted.)
I'm not saying it's the same for your area...just saying what I would do if it were me. There seem to be too many stringing people along, doing unnecessary procedures for every dime they can get...and no healing to be had.
