Tommy John Surgery

Since that time, the treatment of these injuries – including UCL reconstruction – has evolved significantly, and it can help most athletes get back to doing what they love.

What is Tommy John surgery?

Tommy John surgery (UCL reconstruction) is a complete reconstruction of the ulnar collateral ligament (UCL) in the elbow. The UCL stabilizes the inside of the elbow, and an intact ligament is essential for throwing mechanics of overhead throwing athletes. Therefore, UCL reconstruction is most commonly performed after an athlete’s dominant arm sustains a high-grade injury to the ligament.

A graft from the patient’s forearm or hamstring tendon is used to replace the damaged ligament. This provides a new, strong ligament that can allow a full return to throwing.

Who is a good candidate for Tommy John surgery?

Any healthy, overhead-throwing athlete with a complete tear or high-grade partial tear to the UCL of the elbow and who wishes to return to competition is a good candidate for Tommy John surgery. Additionally, those with lower grade injuries to the ligament who have failed conservative treatment are good candidates as well.

How does Tommy John surgery work?

The sutures are tied together to tighten the graft in the appropriate position. While there are dozens of variations described since the original procedure was performed on Tommy John, the three main techniques include the figure-8 technique, the docking technique (described by Dr. David Altchek) and, more recently, the anatomic technique developed by Drs. Josh Dines and Christopher Camp.

As mentioned above, when it was originally described, Tommy John Surgery or UCL reconstruction meant using a tendon graft to create a new ligament, similar to what is done during ACL reconstruction surgery of the knee. More recently, there is renewed interest in repairing the ligament, avoiding the use of grafting a tendon.

This is referred to as a UCL repair, however, some patients still refer to this as Tommy John Surgery. There are benefits to ligament repair, including the lack of needing a graft and a quicker return to play. However, it is critical to choose patients appropriately when indicating one for this procedure. Not all tear types are amenable to this.

Even more recently, the addition of non-absorbable suture to the repair or reconstruction construct has occasionally been used with good results. This addition to the procedure is referred to as an internal brace, and it is done to strengthen the construct allowing the elbow to tolerate higher loads when throwing.

How long does Tommy John surgery take?

Tommy John surgery typically takes about 45 minutes to perform. It can sometimes take longer if there are other injuries that need to be addressed at the time of surgery. Concurrent procedures (those that may be performed at the same time) can include elbow arthroscopy to remove bone spurs or decompression/transposition of the ulnar nerve. The surgeon will make this decision based upon the patient’s history and physical examination. 

What are the potential risks of Tommy John surgery?

The risks of Tommy John surgery are very low, though there are some important ones to consider. The ulnar nerve is close to the surgical site. It is protected at all times, though there is a low risk of injury to the nerve. Other risks of surgery include infection, fracture of the bone, numbness around the incision, or future injury to the new ligament.

What does the recovery from Tommy John surgery look like?

After surgery, the patient will be given an elbow brace that restricts range of motion to protect the reconstruction. This is usually worn for 6 weeks while slowly increasing range of motion. Physical therapy will start soon after the procedure depending on surgeon preference with specific protocols for range-of-motion progression. Assuming they are progressing well, most baseball players will start a gradual return to throwing around the 4- to 5- month mark after surgery.

How long until you can return to sports after Tommy John surgery?

Return to competition largely depends on the sport and position played by the athlete. Most athletes begin a throwing program by 4 to 5 months after surgery. In baseball, pitchers may return to full throwing capacity 12 to 14 months after surgery, although it can sometimes take longer. Position players can return to competition sooner, typically 9 to 12 months after surgery.

What is the success rate of Tommy John surgery?

Tommy John surgery is very reliable and has a success rate of over 90% (with a return-to-play-rate of about 80% to 95%). Younger patients, especially, have low risk of complications or the need for revision surgery. The docking technique for Tommy John surgery was developed at HSS by Dr. David Altchek, and this technique has provided a strong and reliable method to help athletes return to competition.

Do you throw faster after Tommy John surgery?

Some players do throw faster after Tommy John surgery. This is often credited to physical therapy to strengthen the arm and the fact that the athlete once again has a strong ligament that can allow maximum effort throwing without pain. Another key factor here is that, in many cases, during the first 4 to 5 months after surgery when the athletes haven’t returned to throwing yet, they are able to focus on performance training for other things that often get neglected, such as lower extremity and core strengthening, shoulder range of motion, etc.

Can you strengthen your UCL?

There is some emerging research that suggests the ulnar collateral ligament can thicken from throwing and exercise. We are still learning the appropriate balance of exercise and rest to allow for optimal UCL strength. Most importantly, to prevent injury, one can work on shoulder and elbow range of motion and strengthening while at the same time being smart about the amount one throws using strict pitch counts.

Can you heal your UCL without surgery?

Some UCL injuries can heal without surgery. This largely depends on the location and the severity of the injury. Low grade injuries to the proximal UCL have the best chance of healing without surgery. High grade injuries or injuries to the distal UCL are less likely to heal on their own. A doctor with expertise in managing UCL injuries will be able to develop an appropriate treatment plan. When conservative treatment is indicated, cessation from throwing, physical therapy and even platelet-rich plasma (PRP) injections have been shown to play beneficial roles in healing.
