Just a quick update. I had the surgery 3 1/2 weeks ago. My rotator cuff was not as bad as the MRI showed so they took care of some bone spurs and some other arthritic stuff in the shoulder joint. Definitely has made my recovery much quicker.
I wore the sling for the first couple of weeks. This past week I tried out my mowers and I feel I will get by just fine with the dual controls.
Appreciate all the information.
