My bf is having rotator cuff surgery Thursday, how long is recovery time for an operation like this?

This depends on the Dr. and ur BF- It will be the Doctor that gives him the green flag re: his recovery period. Good luck on Thursday- Tell him I wish him good luck. Each person is different. I do have a site below that can perhaps enlighten you more on this surgery and the postop time involved. Good question. Just leave it to the Dr. to give you this answer.
