I'm "only" 66 years old, and have been dealing with osteoarthritis and neuropathy in my feet for over a decade now. I've had problems with my knees for over 30 years, and underwent a partial left knee replacement in 2018, even though we were hoping they'd do a TKR once they got in there. That knee still gives me problems, as well as swelling and pain. Now my right knee needs a TKR, but my orthopedist wants me to lose 40 pounds before he'll do the procedure. I have constant pain and numbness in my feet, along with balance issues. If I have to walk for more than 10-15 minutes, I need my walking stick to help maintain my balance. I've never even considered not having the surgery because of the nerve damage in my feet.
