After my first lateral release and scope I was in a immobolizer for 6 weeks. I had a hard time bending when I first came out of it. I busted my scare tissue myself by, over many days, I got into a tub of hot water, as hot as I could stand, and would get my knee really warm. Then I would rock back and forth with my knee bending a little more each time. When my knee cooled off, I heated it up again and repeated the process. This process worked and I did it on my own, on my own time frame. It might work for you.
