Torn supraspintaus

I while back I wrote about getting an MRI to determine how much damage I had done to my shoulder. It turns out I have a "low grade partial tear" - about 20% - of my supraspinatus - a tendon in my rotator cuff. The doctor recommended more physical therapy before surgery. I was relieved to hear that because the recovery from arthroscopic shoulder surgery, as both he and the therapist explained, is long and painful: about 3 months before I could do anything substantial with my right arm, 6 months til I could be active, and up to year before I'd regain 95% of my original strenght. Ughh. No thanks. I'd much rather do the exercise every day for a year.
