Good symmetry bro. You've done good work with your delts.
Like gman said, read my thread about my post surgery gains. I had a similar knee surgery years ago and the recovery time isn't bad at all. You'll be good to go in no time. Good luck and keep us posted.
oh damn, i thought u were more like 5'11" or 6', none the less, i would kill to have yer arms, im 6'5" and its hard to get thick arms when they are long as fuck.
