I can’t remember exactly but it would have probably been about 6 months and then taking it slow to get back into climbing. I did opt for the open surgery option though as at the time it had slightly better statistics than the keyhole operation, this might be different now.
I now climb just as hard as I did before. The movement you describe is the most unstable position of the shoulder I think, and even now after the repair I am very aware of that position, actively avoiding having to apply pressure on the arm in that position if possible.
I’m glad I’ve had the operation and I’m confident in its strength so all good.
