Depending on what has to be done in repair you'll have probably 6 weeks in a sling and essentially can't use or stress it. Then maybe some physical therapy. (Depends on the surgeon and surgery necessary).
But, IF you fall and automatically put your hand out to stop or break the fall you'll likely rip it loose and have to have it repaired again. I've been told by several orthopedists that one more repair can be done (attempted) and that's it. Chances of a third repair working are very small.
Best wishes on this.
