Interesting stories about shoulder replacement. I've had both done. Right shoulder 9 years ago. Did great with 6 weeks Pt. Sadly, a year ago I started having pain. After prayer and CT Scan it shows that a screw is coming out. Option, new totally redo replacement or just live with it.
Left shoulder done 6 years ago. Another problem, there is a fracture in my scapula where there is a screw. Option, minimize movement and no lifting. Now the fracture is slowly healing.
I have not been lucky with my replacements but I have heard that others have done well. Doctors have no idea why my replacements have not been survived.
Good luck to all of you. Don't give up. Be consistent with your PT. Don't cheat.
