My doc says to try anything before surgery.That is the last option. I know thousands have had TKR but I know several that have horror stories. I'm not a candidate for surgery do to heart and lung problems..
I have had total reverse shoulder replacement by supposedly the best doctor in town. So-so results. Same with two back surgeries.

If God wanted you to walk and carry things on your back, He would not have invented stirrups and pack saddles
