@kt4vq I dodged the need for complete RSR and am recovering (9 weeks) from complex rotator cuff repair. I will echo @ranch - go get it done!

I was in less pain 3 days after surgery than the day before (same tears as you plus bone spurs and torn biceps tendon.) I am 3 weeks into rehab and gaining range of motion daily. I lost nearly 2 years trying to avoid surgery, with PT massage and pain meds - not my best move. And I should have known better, as I have had a number of other joints replaced.

Just do your research, and choose the best possible surgeon - mine came recommended by my PT, a friend whose shoulder he had done and my other ortho (who only does lower limbs).
