aFor ASES, dominant-sided injury, collision, diving for ball, no postoperative recurrence, and no return to sport serve as the reference group. For Rowe, dominant-sided injury, collision, diving for ball, no SLAP tear, no postoperative recurrence, and no return to sport serve as the reference group. ASES, American Shoulder and Elbow Surgeons; N/A, not applicable; SLAP, superior labral anterior-posterior.
