Sometimes it's not a matter of how much you want. It's a matter of how much money you have, how much your body can handle it, and how much time you have on your hands. I don't know which doctor you plan on going to, but I can assure you that 3 surgeries are going to expensive. How much your body can handle is anyone's guess. Most people only do internal femurs and then they stop. After experiencing it and realizing how much work you have to put into it, you might change your mind about tibias. I know I did after spending 5 months now in a wheelchair. I would suggest getting as much length on your femurs as possible - 8 cm or even 10 cm if you can. And to achieve that, you have to really do all of your PT and stretches, and then hope that your soft issue allows you to. You can't get 10 cm from Dr. Paley, but you can with Dr. Guichet. If you can't reach 10 cm on your first try, then you can attempt what YellowSpike is doing and return to Dr. Guichet after consolidating and break your femurs again to finish the rest of the 2 cm. And then do 6 cm or so on your tibs after you've finished consolidating on your femurs. That would probably be the safest and most reasonable. Remember that you put yourself at risk each time you go under surgery, especially if that surgeon isn't good.
