Yes, mine is Tuesday and quite honestly I'm terrified. And I really don't even know why. I'm not afraid of dying or anything like that. Scared I'll be a chicken about pain and whatever. My sister-in-law had a replacement about 12 days ago and is already driving and getting around great. That should encourage me but it just makes me more scared that I won't do as well. I think some of my fear is because they don't know whether they will be doing a PKR or a TKR and I won't know which until I wake up. I'm looking forward to being more active, losing weight and everything for the next year while I recover, but I'm still scared.
