My Dad, who worked in construction for 50 yrs, he had both of his knees and shoulders replaced. That happened 17 yrs ago and they are still holding up, but he said his knees are starting to bother him. The doc said they would last 20 yrs. So not quite there, but he is 87 yrs old and those surgeries relieved the pain that he was in.
My doctor mentioned knee replacement, but he said the arthritis wasn't that bad yet, but it would be a future option. Now just trying to tweak my diet to limit inflamation. I do notice that when drinking sugary drinks does cause pain to increase. So limiting those.
