I understand your concern because my mother just had knee replacement at 65 years of young. She was very apprehensive and fault us all tooth and nail until they told her if she didn't get it done, she'd be faced with other major complications. Unnecessary complications that can be prevented at that, which made her shape up and put her faith where it belongs in the higher power and not the doctors. It's been 3 months and she's doing well and taking her physical therapy seriously.
Tell your mother that she's not the only one that's stubborn as a mule and don't want surgery. My mother was very scared, though she wouldn't say it herself my sisters and I all knew that she was. They turn into babies sometimes, and we just prayed with her and told her that in order for her to be any good to the grandbabies, she had to do it and soon. So just support her and let her know that you're there for her and you understand her anxiety. Do all the things she would've did for you as a child if it was you going into surgery and being scared. That's exactly what my sisters and I did, and it worked out. It was a bit difficult because my mother was a RN for over 35 years, so they're the worse patients just as doctors are.
Take care and I wish you nothing but the best!
