My sling was in use for 4 weeks.
I began formal PT at 4 weeks, although you can do Codman exercises prior to that. Be careful, though, because damaging the repair is more of a concern than adhesive capsulitis. Probably better off taking the arm out of the sling and GENTLY raising it to parallel to the floor in front of you a few times a day.
Right now I am six weeks post-op and have been doing 1# dumbbell exercises for scaption, etc. Here is a good link to use:
Like others have said, the early stages require VERY light weights.
I'll update as I go. Thanks to all who are participating and good luck, guys!
