Can You Have a Second Tommy John Surgery?
Yes, and it is done regularly. But you should go into it understanding that the numbers are meaningfully worse than they were the first time. After a primary reconstruction, roughly four in five athletes get back to the level they left. After a revision, it is closer to one in two. Recovery takes longer, and the chance of further elbow trouble afterward is substantial. Revision is a reasonable operation for the right athlete — it is not a reset button.
How often does a reconstruction fail?
Not often. In a recent comparison of competitive athletes followed to midterm, revision surgery was required in about 8 percent of reconstructions and 9 percent of repairs — a difference that was not statistically significant.
When failure does happen, it is usually not early. In a series of 69 professional pitchers who underwent revision, the average interval between the first operation and the second was 1,424 days — just under four years. These are generally athletes who returned, pitched for several seasons, and then had the graft fail under continued load, rather than reconstructions that never took.
Why grafts fail
Three broad reasons, and they are not equally common.
- Continued load over time. The most common story. The graft held up, the athlete returned and kept throwing, and years of accumulated valgus stress eventually exceeded what the reconstruction could tolerate. This is the four-year pattern in the data above.
- Returning before the graft was ready. The graft is at its mechanically weakest around six months, precisely when an athlete feels strong. Throwing at full effort before ligamentization has progressed puts load on tissue that is not yet capable of carrying it.
- A technical problem with the original reconstruction. Tunnel position, fixation that loosened, inadequate graft tensioning, or bone tunnels that converged or fractured. Less common, but it is the category that a revision surgeon has to identify before operating, because repeating the same error produces the same result.
The underlying cause matters. If an athlete tore a graft because of workload and mechanics that were never addressed, a second reconstruction without changing anything else is unlikely to end differently.
Revision versus primary: the numbers
This is the comparison worth studying before deciding.
| Outcome | First reconstruction | Revision |
|---|---|---|
| Returned to play at any level | ~86% | 76.6% |
| Returned to the same level | 80–84% | 55.3% |
| Average time to return | 9–12 months | 16 months |
| Subsequent elbow injury | — | 29.8% |
| Subsequent elbow surgery | — | 21.3% |
| Required a further revision | — | 6.4% |
The return-to-play figure holds up reasonably well — about three in four pitch competitively again. It is the return-to-same-level figure that changes the picture. Just over half get back to where they were, against roughly four in five after a first reconstruction.
The figures in the last three rows come from professional pitchers followed after revision, and they are the ones that get least attention. Nearly 30 percent sustained another elbow injury, and more than one in five needed another elbow operation of some kind.
It also takes longer
Average time to return to play after revision was 484 days — about 16 months — compared with the 9 to 12 months typically reported after a primary reconstruction.
Graft choice made a difference within that series. Athletes whose revision used a palmaris longus graft returned at an average of 436 days; those with a hamstring graft averaged 540 days, roughly three and a half months longer. Technique mattered too, with docking-style reconstructions returning at 423 days against 519 for the modified Jobe technique.
Practically, this means a revision costs an athlete a season and a substantial part of another.
What makes a revision harder
A second reconstruction is a technically different operation from the first, for several reasons.
- The bone is not virgin. Existing tunnels have to be assessed, and they may be widened, malpositioned, or filled with scar or bone. New tunnels sometimes have to be placed around old ones, and occasionally bone grafting is required in a separate stage before reconstruction can proceed.
- The soft tissue planes are scarred. Scar tissue around the ulnar nerve is common, and the nerve is at higher risk during a revision than during a primary reconstruction.
- Graft options may be depleted. If the palmaris longus was used the first time, the options narrow to the opposite forearm, a hamstring graft, or an allograft. In the revision series above, hamstring autograft was the most common choice at 49.3 percent, with palmaris at 31.9 percent — the reverse of the pattern in primary reconstruction.
- The diagnosis must be right. Not every failed Tommy John is a failed graft. Valgus extension overload, ulnar neuritis, flexor-pronator injury and posteromedial impingement can all produce medial elbow pain in a previously reconstructed elbow. Operating on an intact graft does not help anyone.
What this means for your first operation
The best revision is the one you never need, and there are two things within your control.
The first is completing the rehabilitation properly. The graft is weakest at around six months and there is no symptom to tell you it has matured. Advancing on criteria rather than on the calendar is not conservatism for its own sake — it is the specific thing that protects a graft during the window when it is most vulnerable.
The second is addressing what caused the injury. Workload, rest, mechanics, and throwing year-round on multiple teams do not become irrelevant because someone rebuilt the ligament. An elbow returned to the same conditions that failed it tends to fail again.
Is revision worth it?
For the right athlete, yes. Three quarters return to competitive throwing, and more than half return to their prior level — that is a real chance at a career that would otherwise be over.
But it is a different decision from the first one. A primary reconstruction is close to a routine expectation of getting back. A revision is a considered gamble with meaningfully worse odds, a longer timeline, and a higher likelihood of further elbow problems afterward.
I go through those numbers with patients before scheduling a revision, because someone deciding whether to spend another sixteen months on their elbow deserves to weigh the actual probabilities rather than the hope.
The bottom line
A second Tommy John Surgery? is possible and is performed routinely, but the outcomes are not the same. About 76.6 percent of professional pitchers returned to play after revision and 55.3 percent to their previous level, against roughly 86 percent and 80 to 84 percent after a first reconstruction. Recovery averages 16 months rather than 9 to 12. Nearly 30 percent sustained a subsequent elbow injury and 21 percent required further elbow surgery. Most graft failures occur years after the first operation under continued throwing load, which is why finishing rehabilitation properly and fixing the workload that caused the injury are the two things that most reduce the chance of ever needing a revision.
