Tommy John (baseball player)

Tommy John is a former professional baseball pitcher known for his successful career and for pioneering ulnar collateral ligament (UCL) reconstruction surgery, commonly called "Tommy John surgery." This procedure involves replacing a damaged ligament in the elbow with a tendon graft, restoring stability and allowing players to return to pitching. The surgery is now standard for athletes with elbow injuries, significantly extending careers. Tommy John’s experience and advocacy transformed sports medicine and provided hope for pitchers facing similar injuries.
