Well, technically, he had a scope put into his shoulder joint, and the damage was found. Usually, what happens with an injury to the labrum is that the labrum is separated from the glenoid fossa. The repair is to take sutures and anchors and re-attach the labrum to the glenoid. We keep our post op SLAP repairs immobilized for 3 weeks after surgery and then start PT for passive range of motion with no abduction and no flexion above 90 degrees. Our labral repairs do quite well, but my surgeon isn't operating on world class pitchers either.
Jeez, why don't you leave the topic to those of us who know what we're talking about when it comes to labrum surgery.
