Tommy John Surgery & UCL Repair

Specialized surgical treatment of UCL injuries in throwing athletes, including UCL repair with internal brace augmentation and UCL reconstruction (Tommy John surgery). Treatment is individualized to the athlete's injury pattern, age, level of competition, and performance goals with a focus on safely returning athletes to throwing and competition.

Anatomy of the Ulnar Collateral Ligament (UCL)

The UCL is the primary stabilizing ligament on the inner (medial) side of the elbow. During throwing, tremendous forces are transmitted across the elbow, particularly during the late cocking and acceleration phases of the throwing motion.

The UCL helps resist these forces and maintain elbow stability. Repetitive stress can lead to stretching, partial tearing, or complete disruption of the ligament.

UCL Repair vs Tommy John Surgery

Not all UCL injuries require the same operation.

Advances in sports medicine have expanded the treatment options available for throwing athletes.

UCL Repair with Internal Brace Augmentation

UCL repair involves repairing the athlete's native ligament and reinforcing it with a collagen-coated suture tape known as an Internal Brace.

Common Candidates

  • Younger athletes

  • Acute injuries

  • Proximal or distal avulsion tears

  • Good quality ligament tissue

Potential Benefits

  • Preserves the athlete's native ligament

  • Less invasive than reconstruction

  • Faster rehabilitation

  • Earlier return to throwing

Tommy John Surgery (UCL Reconstruction)

Tommy John Surgery reconstructs the damaged ligament using a tendon graft.

Common Candidates

  • Chronic UCL tears

  • Poor tissue quality

  • Mid-substance tears

  • Failed non-operative treatment

  • Failed prior UCL surgery

Goal

Restore elbow stability and allow athletes to safely return to throwing.

When is Surgery Recommended?

Surgery may be considered when:

  • Non-operative treatment has failed

  • Significant instability exists

  • A complete UCL tear is present

  • Athletes are unable to return to throwing

  • Performance continues to decline despite rehabilitation

The decision to proceed with surgery is individualized and based on the athlete's goals, injury pattern, age, competition level, and examination findings.

Goals of Surgery

The primary goals include:

  • Relieve pain

  • Restore elbow stability

  • Protect long-term elbow health

  • Restore throwing mechanics

  • Maximize performance

  • Facilitate a safe return to sport

  • Return athletes to their previous level of competition

Tommy John Surgery reconstructs the damaged ligament using a tendon graft.

Typical Recovery Timeline

Weeks 0–6

  • Early healing phase

  • Gradual restoration of motion

  • Protection of the reconstruction or repair

Weeks 6–12

  • Progressive strengthening

  • Continued rehabilitation

  • Restoration of normal arm function

Months 3–4

  • Advanced strengthening

  • Plyometrics

  • Sport-specific conditioning

Months 4–6

  • Return-to-throwing progression often begins following UCL repair

  • Continued performance training

Months 9–12+

  • Return to competitive throwing following Tommy John Surgery

  • Ongoing progression based on strength, mechanics, and performance
