 Now, I have a dumb question. When you're going to get a new knee, do they show it to you first? Can you shop for a knee? Or it's like, this is the one you're getting? That is a question that I wish was proposed to me before the surgery, and I would have prevented the revision being done. Really? Yes. Because do they show you the mechanicals and how it works, how it's going to go once we put it inside you?
