 Things are mechanically not going to be able to recover naturally at that point, but we can still make the recovery process better by getting the area of the body in better condition going in. And then, of course, after surgery, I always tell people, let's say you get a joint replacement. We're not treating the arthritis anymore. You don't have arthritis in that joint once it's been replaced. What we are treating at that point is the injury caused from the surgery itself.
