Re: nutritional optimization--lots of leafy green vegetables are especially good for pre-op patients. And pineapple, if you can eat it, contains an enzyme that is anti-inflammatory and pain-relieving (as well as all the vitamins, etc.) It is good for both pre- and post-op diets.

So glad you're getting the surgery--wishing you the best! I know several people who had hip or knee replacements, and they were transformative.
