Total Shoulder Replacement

I have three fully broken tendons (out of four) and my shoulder is dislocated. The dislocation is because there is nothing to hold the upper arm bone where it should be. I’m not sure how this all happened. Possibly degeneration from a fall a few years ago. The surgeon recommends Total Shoulder Replacement, bypassing any other option as they tend to fail. Has anyone had a dislocated shoulder as part of their issue, and how did it all go? In particular, is it ever possible to freestyle swim again. I’m Australian. Not being able to do freestyle laps is most upsetting.
