I didn't want it and found I can go maybe 10 or 12 years if I do no more damage to them
Oh no Penny ! The scariest part of these joint replacements is having them when you are OLD, and the body does not heal near half as well, nor does the immunal system work half as well...so many in their 80s succumb to various infections, even MRSA.
A perfectly exacuted surgery, on a 20 year old would go well, on an 80 year old it can be iffy, and recoop-peration

Putting it off is not a good thing.
