Welcome back, David!
Now, be good and do your physical therapy. It would help a lot if you keep using ice, and your scar will heal better if, in a couple of weeks, you rub some Vitamin E on it.
Didn't they give you that infernal machine that helps you bend the leg a little at the time and you have to use several times a day?
Best wishes for a quick recovery from your fellow bionic PTalker
