After decades of heavy lifting, I was bone on bone with the shoulder ball and socket in both shoulders. The cartilage simply wears thin. This results in large bone spurs that limits range of motion and causes great pain. Because I still wanted an active lifestyle I went to a specialist in the Copeland implant procedure. This is the “resurfacing” discussed earlier. It does allow you to continue to workout, albeit hopefully with lighter weights. My surgeon does have patients that continue to do heavy benches but I wouldn’t. It is a long recovery (1 year +). You can’t do both at once as you need a minimum of 3 months between the surgeries. I am about 8 months out from my second shoulder and am able to do most everything but not heavy plus I have eliminated overhead pressing movements because at the end of the day, like Gotgame said, I don’t want a revision surgery and it’s limitations for the rest of my life...
