Tommy John surgery, also known as ulnar collateral ligament (UCL) reconstruction, is a common procedure primarily performed on athletes whose sports involve repetitive overhead motions, such as baseball pitchers. Town Center Orthopaedics’ (TCO) orthopedic surgeon Dr. Baris Yildirim explains what you need to know in this article and video.

UCL Tear? FAQ About Repair With Tommy John Surgery

As a hand and upper extremities surgeon who focuses on sports injuries in the arm, Dr. Yildirim specializes in Tommy John surgery at TCO. This procedure has been a game changer for those who otherwise may have ended their sports careers because of torn UCLs. He’s prepared the following questions and answers to help you understand what to expect from the surgery and its recovery.

What Is Tommy John Surgery, and Why Is It Common for UCL Injuries?

Tommy John surgery is performed to reconstruct the ulnar collateral ligament (UCL) in the elbow.

“The UCL is a ligament that stabilizes the inside of your elbow and plays a critical role in throwing and activities that put the elbow under a lot of stress,” Dr. Yildirim explains. “The tears are often seen in pitchers, but we also see them in athletes who play tennis, football, wrestling, and javelin throwers.”

When repetitive strain leads to partial or complete tears in the UCL, surgical intervention often becomes necessary to restore stability and function. Before the introduction of Tommy John surgery, these tears were career-ending, as surgeons tried to repair tears that couldn’t hold. The difference with Tommy John surgery, first performed by Dr. Frank Jobe, was that it recreated the ligament rather than trying to repair it. The surgery involves taking a tendon from another part of the body or using a donor tendon to replace the damaged UCL.

Why Is It Called Tommy John Surgery, and How Has UCL Reconstruction Evolved?

The surgery is named after Tommy John, a major league pitcher who underwent the surgery in 1974 for the first time. After the surgery, “he was able to get back to pitching in the major leagues and continue to pitch at a very high level,” Dr. Yildirim shares.

The procedure has evolved since then, with advancements in surgical techniques and rehabilitation protocols contributing to improved athlete outcomes.

What Are the Key Symptoms of a UCL Injury, and When Should Surgery Be Considered?

How to know if you need Tommy John surgery: According to Dr. Yildirim, UCL injury symptoms can present in different ways. “Sometimes, the athlete will feel a pop with pain and have difficulty throwing. Other times, it can be insidious with pitchers having more chronic elbow pain while throwing and decreased pitching velocity.”

Some may also experience numbness or tingling in their ring or small fingers due to nerve proximity to the UCL.

If a UCL tear is diagnosed, it’s important to know whether it’s a partial or complete tear.
“Partial tears with stable elbows are often treated without surgery with a period of rest, followed by physical therapy and a progressive return to activity focusing on improved throwing mechanics and strength,” says Dr. Yildirim.

On the other hand, complete tears in high-level athletes are often treated with surgery followed by extensive therapy.

What Is Tommy John Surgery Like?

During the surgery, the surgeon makes an incision on the inner side of the elbow to access the damaged UCL. Depending on the specific condition of the ligament and the patient’s demands for sport, the surgeon may choose from different techniques to reconstruct it. The most common method involves harvesting a tendon from another part of the patient’s body or using a donor tendon. This harvested tendon is then threaded through holes drilled in the bone to create a new ligament structure, effectively replacing the damaged UCL.

How long does Tommy John surgery take? The surgery is performed under general anesthesia and takes approximately 60-90 minutes.

How Can Patients Ensure a Full Recovery From UCL Reconstruction?

Recovery is a time-consuming process, but it’s vital for a full recovery. Complete recovery can take anywhere between nine to 18 months, and “it’s dependent on proper rehabilitation and diligent adherence to the protocols,” Dr. Yildirim says.

Recovery involves several phases:

  • Initially, the emphasis lies on protecting the surgical site and managing pain. This early period generally lasts for a few weeks and involves wearing a splint or brace to stabilize the elbow while allowing for healing.
  • As healing progresses, the next phase introduces gentle range-of-motion exercises to prevent stiffness and promote flexibility in the elbow joint.
  • Between six to 12 weeks after surgery, athletes can begin strengthening exercises to rebuild muscle strength and stability in the surrounding shoulder and arm muscles.
  • The final phase is often the most critical for athletes, as it involves a gradual return to throwing and sport-specific activities. This phase can take anywhere from six months to a year, depending on the individual’s healing process and the specific requirements of their sport.

Dr. Yildirim cautions that the key is not to rush through the rehab process. “Without the patient’s willingness to undergo the extensive rehab, it may be wise to even think about not going through the operation because the surgery also comes with risks. However, with good rehab, we can achieve a high rate of return to the sport after these injuries.”
