Rehab after Tommy John surgery, a reconstruction of the elbow’s ulnar collateral ligament, is long: the American Academy of Orthopaedic Surgeons says complete recovery takes about 12 to 18 months. The early months protect the new ligament in a brace while restoring motion; the middle months build forearm, shoulder, trunk and hip strength; the final stretch is an interval throwing program. In Carmel, the matching team can connect throwers with an independent, licensed physical therapist for one-on-one rehab.

- Complete recovery
- About 12 to 18 months (AAOS)
- Early protection
- Splint, then a hinged elbow brace
- Throwing restart
- An interval program when the surgeon allows
- Return to prior level
- Roughly 80 percent of patients (AAOS)

Why does Tommy John rehab take more than a year?
It takes that long because the new ligament, usually a tendon graft taken from your forearm, hamstring or a donor, has to mature into tissue strong enough to resist the force of throwing. That process is slow, and every hard throw places very high stress on the inner elbow.
The ulnar collateral ligament (UCL) runs along the inner side of the elbow and stabilizes it when the arm cocks back to throw. OrthoInfo explains that UCL injuries are most common in overhead throwers because of repetitive high stress, and that pitchers often notice pain on the inside of the elbow and lost velocity before a complete tear. Volleyball, javelin and position players can be affected too.
OrthoInfo reports that about 80 percent of patients return to their previous level of competition after reconstruction, with lower rates after a second surgery. That makes the patient, criteria-based progression worth it.
What happens in each phase of rehab after UCL reconstruction?
The phases run from protection and motion, to strength through the whole body, to throwing. Timelines vary with the surgeon, the graft and whether a repair that reinforces your own ligament with an anchor and strong suture was used instead of a reconstruction, which some surgeons progress faster.
| Time after surgery | Goals | Typical milestones |
|---|---|---|
| 0 to 2 weeks | Protect the graft, settle swelling | Splint; hand and wrist movement; grip with a soft ball |
| 2 to 6 weeks | Restore elbow motion within brace limits | Hinged brace opened in stages; shoulder and shoulder blade work without stress on the inner elbow |
| 6 weeks to several months | Build strength through the chain | Forearm and wrist strengthening; rotator cuff and shoulder blade program; hip, trunk and leg strength |
| Middle months | Interval throwing from flat ground | Begins only when the surgeon allows; distances, effort and throw counts increased in steps |
| Later months | Mound work and competition | Bullpens, then simulated and live innings; OrthoInfo gives 6 to 9 months or more for competitive throwing and 12 to 18 months for complete recovery |
Why does a Tommy John rehab program train the hips and trunk so much?
Because most of the speed of a pitch is generated by the legs, hips and trunk, and an elbow that is asked to make up for a weak or stiff lower half takes more stress. OrthoInfo notes that UCL rehab addresses forearm strength, core work and hip mechanics, not only the elbow.
A typical session may include lead-leg and back-leg strength work, hip rotation mobility, anti-rotation core exercises with a cable, and the prone Y, T and W and banded external rotation for the shoulder. Programs often follow the Thrower’s Ten, a widely used set of exercises for throwing shoulders and elbows.
The private suites at FlexWerk have a rack, cable system and dumbbells for this strength work, and the indoor turf corridor gives room for early throwing drills with light balls if your therapist and surgeon agree. Long-toss and mound work happen outdoors or at a facility with a mound.
- Wrist flexor and forearm strengthening to support the inner elbow
- Rotator cuff and shoulder blade endurance
- Hip strength and rotation on both legs
- Trunk rotation and anti-rotation control
- Throwing mechanics review before the interval program
What do the surgeon and coaches control during Tommy John recovery?
The surgeon controls brace settings, when strengthening against resistance begins, when throwing starts and when the athlete may pitch in a game. The physical therapist runs the program within those decisions and reports progress back.
Coaches and parents control the schedule outside therapy, and that is where problems often start: an extra bullpen, a showcase weekend, a request to play a position before the throwing program is complete. A written interval throwing program with dates, distances and pitch counts, shared with everyone involved, protects the athlete. For youth players, Major League Baseball’s Pitch Smart guidelines give age-based pitch count and rest advice after return.

Soreness rules are a common tool during the throwing phase. Many interval programs ask the athlete to note soreness the day after each session: general muscle soreness that fades with warm-up usually means continue, while pain on the inner elbow that lingers or returns during throwing means stepping back a stage and telling the therapist. Writing those notes down makes the conversation with the surgeon far more useful than memory alone.
Velocity is the last thing to chase. Programs usually build distance and accuracy at moderate effort first, and radar guns are often kept away until late in the process, because trying to hit an old number early tempts the athlete to throw through warning signs.
Is prehab worth it before Tommy John surgery?
Yes, when time allows. Restoring full elbow straightening as far as the injury permits, keeping the shoulder, hips and trunk strong, and practicing the early-phase exercises can make the first months smoother. Surgery is rarely an emergency, so there is usually a window.
Prehab is also the moment to set expectations. A year or more away from competitive throwing is normal, and the athlete, family and coaches should understand that before surgery rather than discovering it in month four.
Mental preparation counts as well. A long rehab can feel isolating for a player who is used to being part of a team every day. Staying involved, keeping a training log, and treating strength sessions as the athlete’s new practice schedule help many players keep going through the slow middle months, when the elbow feels normal but throwing is still restricted.
What should young throwers and their families in Carmel plan for?
Plan for a long season away from pitching, a structured program with regular therapy check-ins, and a clear handover back to coaches. Many central Indiana players compete in travel baseball and softball, including events at Grand Park in Westfield, and summer schedules can tempt a rushed return.
For athletes under 18, a parent or legal guardian completes the two-minute questionnaire and attends sessions. The matching team will say honestly whether a therapist in the network with throwing-athlete experience is available before anything is booked. Our page on return-to-sport testing explains how strength and readiness are measured before competition.
Contact the surgeon promptly after UCL reconstruction if you notice
- New or increasing tingling or numbness in the ring and little fingers (the ulnar nerve)
- A pop or sudden inner elbow pain during exercise or throwing
- Wound redness, drainage or fever
- Loss of elbow motion that is getting worse rather than better
If you think it is an emergency, call 911.
