i had both shoulders with tears and had surgery 4 months apart .
first surgery was for a complete tear and there was more to it than just the rotator cuff surgery, ended up having to have some bone in the shoulder also removed. had tendons resewn besides shoulder mucsles.
it took 6 months for that to heal with complete range of motion. i was put on a special chair that did the movement for me 12 hours after surgery.
i had my surgery 11 years ago and maybe this is outdated for how they do the surgery and recovery treatment now.
the ins. co rented the same physical therapy motorized chair and had it delievered to my home before i was released from the hospital. the therapist set the dials and programmed the position and pace of movement for the arm. my arm was velcroed on top of the mechanical arm. used this machine for 5 times a day for 15 minutes at a time. after a month of that, drove to physical therapy for sessions 2x's a week. out patient sessions lasted for 4 months as i did not have full range of motion in that arm.
for 2.5 months i was in a elastic type of immobilizer/strap that held my arm against my body so no movement was possible except when i had to use the chair or physical therapy. try washing your hair with one hand.......
second rotator cuff was a piece of cake. recovery was only one month with physical therapy. maybe i took more pain pills after this surgery and just didn't feel the intense pain during recovery.......
i feel your pain on the surgery and recovery.
i ended up with full shoulder surgery with the complete tear r. cuff surgery.
most people don't.
even if you have arhtroscopic surgery, it still hurts as bad.
good luck on your recovery. docs only can predict how long it will take to get your full range of motion back. one month out of surgery you will still have pain and trouble sleeping. another month from now you should be feeling better.
