Good advice from HawkOwl. Healing is very individual and doctors are very fallible. A month before turning 60 I broke my arm just below the rotator cuff. Orthopedist said the shoudler was likely damaged and I would probably need a new one within 10 years. PT was painful and took 6 months to get back to normal. It's been 11 years and I have had no problems with the shoulder at all.
