Oh, I almost forgot. On the subject PT to restore your range of motion:

PT did little for me, frankly. I think the problem was the exercises concentrated on either range of motion or strength, and the exercises were boring and even when done religiously ... not enough.

But worked swimmingly well (pun intended) was swimming. The crawl stroke, in particular, is great for regaining both range of motion and strength at the same time. I recovered full range of motion in short order when I started doing that.

YMMV, of course.
