2016 I had a complete right shoulder replacement at age 66. My Doctor was the Cincinnati Reds Team Ortho for 11 years. Shoulder was installed on Monday. Tuesday I saw the PT at which time the sling was removed, inspection made, directions given about allowable movement AND confirmation that I could get back on my bicycle the following day for an easy ride. I waited until Thursday and biked 10 miles without issue. Six weeks later I rode Six Gap Century of 103 miles and 11,000' climbing. Replacement heals quicker than repair. July 4th this year a bike mishap caused a left shoulder MINOR ROTATOR CUFF tear. I am still nursing that injury with my riding abilities still compromised.

IMO, one should do as was mentioned earlier in THREAD, seek out a very experienced ORTHO with PROFESSIONAL sports injury background.
