Hi all. I don't usually participate in forums, but I really need the advice of people who have faced my dilemma. I am a 49 year old woman who has had lupus & RA for 30 years. I've had both knees replaced, 3 hip replacements, and about 13 months ago, had a shoulder replacement (not a reverse replacement). I had a torn rotator cuff and a torn bicep tendon before surgery. This has been the most frustrating recovery of any surgery I've had. After 13 months of PT, I still can't lift my arm more that about 65 degrees. I am very petite and have small bones and osteoporosis. When I lift my arm, it's like it catches on something, and once I get past the catch, I can lift it all the way (when lying down, not standing up). I think my surgeon thinks the prosthesis may have been too large. I'm going for a CT scan on Monday and considering a revision. What is the success rate of this, is it worth going through another year like the last, or is lifting my arm highly overrated?
