So the ortho just told me my arthritis is at the "end of the road" and the only thing left for me is double replacement. The problem is I'm only 46 and the equipment only lasts around 20 years so there's a good chance I'll need it again in the future. Does anyone have any experience with this? If I get the surgery, will I ever be able to lift the same again? Or is the gym as I know it over with?
