Robert...We will be hurting together. I'm getting my Rt. knee replaced on Dec 16 and my left ASAP after that ! It will be fun to compare notes. I'm in so much pain right now I don't know if it will be any worse. I had to return from our home in Baja because of the pain and I ran out of Vicoden ! I was considering having both done at once but have been talked out of it. Good Luck to you Robert !............Bruce
