Dang those are some gnarly scars. I hope PT does the trick and you can get back to 100%.
I had shoulder surgery in '07, and I healed up even with PT I had limited range of motion, so I went to my chiropractor and he used this penetrating laser on it to break up scar tissue. He only had to do it one time and it literally worked in minutes and increased my range of motion almost to normal.
So if PT seems like its taking a long time to work then that might be something for you to look into.
Good luck with everything dude! I know it sucks being laid up like that
