Not every UCL injury requires the same surgery. Choosing the right procedure starts with understanding your specific tear, your timeline, and what it will take to return to the sport you have worked your career to play. This page explains the two operations, how the decision gets made, and what changes once we are in the operating room.
- Two procedures
- Repair or reconstruction
- Repair suits
- End-avulsion tears, healthy ligament body
- Reconstruction
- Three-layer hybrid technique
- Decision driven by
- Tear pattern and tissue quality
- Finalized
- Sometimes intraoperatively
- Graft source
- Palmaris or hamstring
01 Getting the diagnosis right
Start with an evaluation by someone who focuses on this ligament
The first thing I tell athletes who think they have a UCL injury is to make sure they are being evaluated by a surgeon who specifically focuses on the treatment of this ligament. UCL injuries exist on a spectrum from mild sprains through complete tears, and the nuance in that spectrum matters enormously when it comes to choosing the right path forward.
Before any surgical discussion happens, a thorough evaluation is necessary. That includes a detailed history of how and when the injury occurred, a physical exam of the medial elbow, and appropriate imaging, usually radiographs to evaluate the bony architecture and an MRI to characterize the ligament itself. The MRI findings, in combination with the clinical picture, are what drive treatment decisions.
Not every UCL injury requires surgery, and not every non-operative UCL injury requires an injection. Many partial tears respond well to a structured rehabilitation program built around flexor-pronator strengthening, a period of valgus stress avoidance, and a graduated return to throwing. Surgery becomes the conversation when those options have been exhausted, or when the injury pattern makes non-operative management unlikely to succeed.
If an athlete has a complete UCL tear and hopes to return to overhead or throwing sport at a high level, surgery is usually the appropriate discussion to have sooner rather than later.
02 The two surgical options
What actually separates repair from reconstruction
There are two fundamentally different surgical strategies for the UCL. Which one is right for you depends on what your ligament looks like on imaging and what we find at the time of surgery.
UCL repair with internal brace
- Best suited to acute injuries at the proximal or distal attachment of the ligament
- Requires that the remainder of the ligament is intact and structurally healthy
- Native ligament is repaired back to bone using anchors and high-strength suture
- Internal brace acts as a load-sharing construct that protects the repair during healing
- No graft harvest required
- Generally a shorter recovery than reconstruction
Hybrid UCL reconstruction
- Appropriate when the ligament is not amenable to primary repair
- Historically the gold standard, commonly known as Tommy John surgery
- Autograft tissue harvested from the wrist or the knee
- Three-layer hybrid technique rather than a standard Tommy John
- Underlying ligament is repaired and reinforced before the graft is placed
- Maximizes biological restoration of the medial elbow
Recovery time is a consideration, but it should never be the deciding factor. What matters is the procedure that gives your elbow the best structural foundation for the demands you are going to put on it.Matthew Fury, MD
03 Repair with internal brace
When repair is the right answer
UCL repair with internal brace is an important strategy within the treatment algorithm, and it applies when the situation dictates it. The concept is straightforward. If the ligament is torn at one end, either off the medial epicondyle proximally or off the sublime tubercle distally, and the body of the ligament itself is healthy, the most biologically sound approach is to repair what tore rather than replace the whole structure.
The technique involves placing suture anchors at the bony attachment and using high-strength suture to reattach the torn ligament where it belongs. That repair is then protected and reinforced with a synthetic load-sharing construct, the internal brace, which takes stress off the repair while healing occurs.
The advantages are meaningful: no donor site, less surgical dissection, and in the appropriate patient, a faster return to sport than reconstruction. I want to be clear about how that factors in, though. A shorter recovery is a benefit of repair in the patient whose injury is repairable. It is not a justification for repairing an injury that requires reconstruction, and athletes sometimes arrive having been told otherwise.
04 Hybrid reconstruction
A more advanced approach to Tommy John surgery
When the ligament is not repairable, whether because of the tear pattern, the quality of the remaining tissue, or the chronicity of the injury, reconstruction is the appropriate treatment. This is the procedure most athletes recognize as Tommy John surgery, and it has an excellent long-term track record of returning throwers to high-level competition.
What I perform is a modified version that goes beyond the traditional reconstruction. It is a hybrid, or suture-augmented, reconstruction, and it creates a three-layer treatment effect that I consider a meaningful advancement over the classic technique.

Graft harvest
Autograft tissue is taken from either the palmaris longus tendon at the wrist or a hamstring tendon at the knee, depending on your anatomy and which source provides the best material to work with.
-
Repair and reinforcement of the native ligament
Rather than removing what remains of the UCL and replacing it with graft, I first repair the underlying native tissue and reinforce it with high-strength suture in the same load-sharing configuration used in a primary repair. The goal is to restore the anatomy of your own ligament rather than discard it.
-
Graft reconstruction
Bone tunnels are placed in the medial epicondyle and the sublime tubercle, and the autograft is woven and secured to reconstruct the UCL in its anatomic position, adding a third layer of structural support over the repaired and reinforced native tissue beneath it.
The result is an elbow rebuilt in layers: native tissue repaired, synthetic reinforcement applied, and autograft reconstruction providing the final structural layer. For the right patient, I believe the biomechanical and biological environment this creates gives the elbow the best available foundation for a durable return to high-level throwing.
UCL surgery does not happen in isolation. Depending on your anatomy and what we find at the time of surgery, treatment of the ulnar nerve, the flexor-pronator mass, or intra-articular elbow pathology may be incorporated into the same procedure. Those decisions come from your pre-operative evaluation and intraoperative findings, and they are made case by case.
05 The bottom line
Both procedures work when they are chosen for the right reason
Repair and reconstruction both carry high rates of success in returning overhead athletes to their prior level of performance. The published data on this is encouraging, and my own experience with both procedures reflects it. The outcome of either one depends substantially on whether it was the right choice for that specific injury in the first place.
That individualization, looking at the history, the exam, the radiographs, and the MRI together and then having an honest conversation about what the options actually are, is the part of this process I take most seriously. UCL surgery does not lend itself to a standard treatment plan applied uniformly, and I do not approach it that way.
If you are an athlete dealing with a UCL injury, the most important first step is an evaluation with someone who focuses on this. That conversation shapes everything that follows it.

06 Common questions
Questions about UCL surgery
Is the recovery much different between repair and reconstruction?
The early phases are quite similar. Both involve a splint for roughly seven to ten days before transitioning into a hinged elbow brace and beginning a gradual restoration of motion. A structured strengthening phase follows, with progressive reintroduction of valgus stress before the throwing preparatory phase and an interval throwing program.
The difference shows up in the overall timeline, where repair generally allows an earlier return to sport. Every athlete recovers at a different pace, and we treat progression as a function of tissue healing and functional milestones rather than a calendar.
Is there a difference in pain between the two procedures?
In our experience, no. Most patients tolerate both procedures well, and we have not seen a meaningful difference in post-operative pain between them. Both involve the medial elbow and use essentially the same pain management protocols.
A reconstruction that includes graft harvest, particularly from the knee, can produce some additional soreness at the donor site in the early weeks. It typically resolves without issue and does not change the overall pain experience in any significant way.
Is the decision made before surgery, or does the plan sometimes change in the operating room?
Both, and we are transparent about that from the start. In many cases the history, physical exam, and imaging let us discuss both options ahead of time and explain the criteria that point toward one or the other. Some injury patterns clearly dictate reconstruction, and that conversation is more straightforward pre-operatively.
We enter the operating room with a preliminary plan that may be refined based on what we actually see: the tissue quality, the tear pattern at its margins, how the ligament responds to tension. For that reason, surgery is sometimes booked as UCL repair versus reconstruction, with the final decision made intraoperatively. We put a strong emphasis on educating patients thoroughly beforehand so that whatever the right option turns out to be, they walk in prepared for it.
Does Dr. Fury perform both UCL repair and reconstruction?
Yes, along with the full spectrum of UCL surgery: primary repair with internal brace, standard reconstruction, hybrid and augmented reconstructions, revision UCL surgery, flexor-pronator tendon repair, ulnar nerve surgery, and treatment of bone spurs and osteochondritis dissecans.
This matters more than it might seem. No two throwers present the same way, and treating the entire spectrum of medial elbow pathology is what allows the operation to be selected for the injury rather than for the surgeon's comfort with a particular technique.
How often will I see Dr. Fury for follow-up after surgery?
Follow-up is structured around the milestones that matter. Patients are seen one week post-operatively for a wound check and to transition out of the splint, again two weeks later, then at 6 weeks and 12 weeks, followed by visits that assess throwing readiness and progression through our guided program back to competition and performance.
Each visit is an opportunity to assess where you are, adjust the program, and keep the plan matched to your progress rather than to an average timeline.
When can I resume working out after UCL surgery?
Earlier than most people expect. We encourage athletes to stay active in the post-operative period, and low-intensity aerobic exercise along with lower extremity and opposite-arm strengthening can begin right away. The one early restriction is avoiding heavy sweating for the first three weeks to minimize any risk of wound complications while the incision heals.
Once the wound has closed, usually around three weeks, that restriction lifts and workouts progressively increase in intensity. The goal is to have you fully back in the weight room on a structured strengthening program before the throwing progression begins, at your pre-injury strength or better. Returning to the mound stronger than you were is part of protecting the elbow when throwing load starts to build back up.
