Greetings from Canada! I had extensive reconstruction on both shoulders, the left in 2001 and the right in 2011. Both involved anchors and long-bicep tenotomies, and shaving the inner lining of the socket to allow more room. Cutting the long-bicep tendon left the muscle partially free to dangle and it now bunches up and looks like Popeye. It also reduces the strength in your arm by about 30%, which was problematic in my line of work (millwright). Be sure to talk to your surgeon about this. Despite over 90 PT sessions and countless hours of exercising at home, neither shoulder was restored to an adequate degree of function to enable me to continue working in my field. I had to start a new career path following the first surgery, and I was involuntarily medically retired at 57 years following the second surgery. Constant pain in both shoulders, the left greater than the right, and restricted lifting range has permanently changed my life. Weight limit below shoulder height in both arms is unrestricted, but over shoulder height it is limited to 5 lbs in left and 10 lbs in right. And sleeping is very challenging.

On the other hand, my uncle had a reversal done in one shoulder and got very positive results. He was very committed to the therapy and home exercises, and his range of motion was greatly improved while dramatically reducing his pain. Though he was not able to continue in his job, he was able to re-train in another field that still was physical in nature, but a little less demanding. He worked over 20 more years until his retirement at age 75.

Remember; treat your recovery like a full-time job. Take it seriously and don't slack. If you don't use it, you'll lose it. Good luck.
