I had a slight tear, so probably not the same - but I got turned onto something called "Shoulder Reliever" (
https://shoulderreliever.com/) and I thought it was worth a shot. I was skeptical, but read nothing but great things and gave it a shot. It cured mine 100%. My boss, who is too old to surf, but still loves to surf was talking about how it messes up his shoulder every time and I told him about it. He got one too and now swears by it too.
Not sure it could fix something that needs surgery - but might be worth a shot? And if anyone else reading this has a "crunchy" shoulder that gives them fits when doing push ups, bench press (I gave this up) or wakes them up at night - this thing worked like magic for me and my boss.
If this info can help anyone else - just passing it forward as it did for me.
