Abstract
Background: The anterior bundle of the ulnar collateral ligament (UCL) is the primary anatomical structure providing elbow stability in overhead sports, particularly baseball. Injury to the UCL in overhead athletes often leads to symptomatic valgus instability that requires surgical treatment. Hypothesis: Ulnar collateral ligament reconstruction with a free tendon graft, known as Tommy John surgery, will allow return to the same competitive level of sports participation in the majority of athletes. Study Design: Case series; Level of evidence, 4. Methods: Ulnar collateral reconstruction (1266) or repair (15) was performed in 1281 patients over a 19-year period (1988—2006) using a modification of the Jobe technique. Data were collected prospectively and patients were surveyed retrospectively with a telephone questionnaire to determine outcomes and return to performance at a minimum of 2 years after surgery. Results: Nine hundred forty-two patients were available for a minimum 2-year follow-up (average, 38.4 months; range, 24-130 months). Seven hundred forty-three patients (79%) were contacted for follow-up evaluation and/or completed a questionnaire at an average of 37 months postoperatively. Six hundred seventeen patients (83%) returned to the previous level of competition or higher, including 610 (83%) after reconstruction. The average time from surgery to the initiation of throwing was 4.4 months (range, 2.8-12 months) and the average time to full competition was 11.6 months (range, 3-72 months) after reconstruction. Complications occurred in 148 patients (20%), including 16% considered minor and 4% considered major. Conclusion: Ulnar collateral ligament reconstruction with subcutaneous ulnar nerve transposition was found to be effective in correcting valgus elbow instability in the overhead athlete and allowed most athletes (83%) to return to previous or higher level of competition in less than 1 year.
