Tommy John Surgery

UCL reconstruction surgery for athletes with ulnar collateral ligament injuries. This procedure uses a tendon graft to reconstruct the damaged ligament in the elbow.

What is Tommy John Surgery?

The ulnar collateral ligament (UCL) is located on the inner side of the elbow and is critical for stability during throwing motions. When the UCL is torn—often from repetitive stress in throwing athletes—it can cause pain, instability, and inability to throw at full velocity.

Tommy John surgery reconstructs the damaged UCL using a tendon graft. The graft acts as a scaffold that the body gradually incorporates, restoring elbow stability and throwing function.

Who May Need This Surgery?

  • • Baseball pitchers with UCL tears
  • • Javelin, tennis, and overhead athletes
  • • Medial elbow pain with throwing
  • • Elbow instability during arm motion
