Since I needed both replaced equally as much, I had both done at the same time. It's been six wonderful years ago. My advice: Choose your doctor carefully. This is so important for a good outcome. Do your rehab faithfully, even when you don't feel like it or it hurts terribly--this is essential. The advice about dental health is important, too. Don't become a couch potato. Do what you can, when you can, and push yourself a little but not to excess. I had the traditional surgery done. Now many are choosing the side incision, which has even faster recovery. Only other thing I can think of is sleep positions afterward. For the first few weeks it's hard to sleep on your side (at least, it was for me. Maybe not if you just get one done). Good luck. It will really improve your quality of life and you will be so glad you chose to go for it.
