Tommy John Surgery
Tommy John surgery reconstructs the ulnar collateral ligament (UCL) on the inner side of the elbow using a tendon graft. The UCL stabilizes the elbow during throwing, and tears are most common in baseball pitchers and other overhead athletes. The surgery is named for the pitcher who first returned to the major leagues after it in the 1970s.
Procedure overview
What happens during Tommy John Surgery?
- Performed under general anesthesia as an outpatient procedure, typically taking about one to one and a half hours.
- A tendon graft, often from the forearm or hamstring, is woven through the elbow bones to rebuild the ligament.
- A brace protects the elbow for the first several weeks while motion is gradually restored.
- A structured throwing program typically begins around four months after surgery.
- Return to competitive pitching commonly takes twelve to eighteen months; position players and non-throwers often return sooner.
Recovery
What is recovery like after Tommy John Surgery?
Tommy John surgery (reconstructing the elbow's ulnar collateral ligament) is followed by one of the longer rehabs in orthopedics, especially for throwing athletes. The elbow is usually protected in a brace early, with motion added gradually over the first weeks. Strengthening builds over months, and throwing is reintroduced slowly through a structured, stage-by-stage program. Return to competitive throwing commonly takes about twelve to eighteen months, and following the progression exactly is what protects the new ligament. Non-throwing daily activities return much sooner. Contact your surgeon about fever, spreading redness, numbness or tingling in the hand, or a sudden loss of strength.
Common questions
How long is recovery from Tommy John surgery?
For pitchers, return to competition commonly takes twelve to eighteen months, moving through strength work and a progressive throwing program. Non-throwing activities return much sooner.
Does a UCL tear always need surgery?
No. Partial tears are often treated first with rest, physical therapy, and a gradual return to throwing; some athletes also discuss newer repair options with their surgeon. Reconstruction is typically for complete tears or failed non-surgical care in throwers.
What is the difference between UCL repair and reconstruction?
Repair stitches the athlete's own ligament, sometimes with reinforcing tape, and may allow a faster return in select tears. Reconstruction replaces the ligament with a graft and remains the standard for many complete tears, candidacy depends on tear location and tissue quality.
