4 yrs later, i have weakness+significant pain where surgery had placed a screw in the long tendon fro rotator cuff surgery- what r the success rates?

See your surgeon!: See your surgeon for his/her opinion. If you do not get satisfactory information, get a second opinion. We cannot see your xrays and MRI's and so cannot give you any more advice about this. You may consider a Healthtap Concierge with an orthopedist, but this will help you the most if you can upload copies of your imaging studies. Good luck. Try to have a Happy Holiday Season anyway!
