I had a total shoulder replacement by Dr. Sperling at Mayo Clinic about seven years ago. I consider the operation a complete success. Rehabilitation took quite a bit of time and I had my arm in a “contraption” so it could not move for several months. It was well worth it as not only was I in terrible pain before the operation, I had lost almost all range of motion. I am now looking at a rotator cuff surgery and plan to go back this summer and have that done.
