Good for you on the weight loss! I, too, have cut back on sugar. Stevia in coffee, just the odd dessert now and then. No soda. I do have some osteoporosis - minimal in spine, worse in femoral tips according to dexa scan. Surgeons do not check x-rays for osteoarthritis around TKR, as far as I know. There only concern is that prosthetic still being firmly in place. I go back in Jan for yearly check. I will make my wishes known to check for osteo in rt knee. Thanks to you for your response and have a very peaceful holiday!
