@babette I am sorry for what you have had to endure but very glad that you finally have a solution. If I recall, the surgeon with whom you consultedj was the one who did my knee and with whom I was/am very happy.
I had a friend who went through two years of pain and limping before finally getting help from a surgeon at that hospital. I suspect you will be seeing the same surgeon. She was very happy with what he did for her. Her initial surgery was up here in NH.
