Common shoulder & elbow concerns we treat

  • Pain that limits walking, lifting, or sleep
  • Stiffness, swelling, or reduced range of motion
  • Sports injuries: acute or overuse
  • Arthritis or post-traumatic joint changes
  • Conditions other doctors couldn't resolve

What sets LAOSS apart

  • Same- or next-day appointments at eight Los Angeles-area offices
  • On-site imaging; PT coordinated with your in-network provider
  • Conservative-first care, surgery only when needed
  • Board-certified specialists, not generalists

Key takeaways

  • A UCL tear is one of many shoulder & elbow conditions our specialists evaluate every day.
  • Partial UCL tears often recover with rest and a structured throwing program. Complete tears in throwing athletes usually need surgery.
  • When a procedure is the right call, we explain every option, recovery timeline, and return-to-activity milestone.
  • On-site imaging at most offices and same-day appointments across eight Los Angeles-area locations.

What is a UCL tear?

A tear of the ulnar collateral ligament (UCL) of the elbow, known as a Tommy John injury, is common in baseball pitchers and overhead athletes, often requiring surgical reconstruction to return to throwing. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.

Treatment depends on the size of the tear and what you need the elbow to do. Partial tears often recover with rest from throwing, physical therapy, and a gradual return-to-throwing program; PRP injections are an option in select cases. Complete tears in athletes who want to return to throwing usually need surgery, either a repair or a reconstruction (Tommy John surgery).

Below, we walk through the anatomy involved, the symptoms and causes we most often see, how we diagnose a UCL tear, and the full range of treatment options, from the simplest to the most involved.

Watch: Ulnar Collateral Ligament Injury

Like other joints, the elbow is held together by strong bands of tissue called "ligaments." On the elbow's inner side is the ulnar collateral ligament complex. We call it the "UCL." It's made of three bands that connect the humerus (the upper arm bone) to the lower arm's ulna. The UCL is the elbow ligament most often injured by baseball pitchers and by other athletes who play throwing sports.

Inside the shoulder & elbow.

The shoulder is the most mobile joint in the body, which makes it vulnerable to instability and impingement. The elbow is a hinge that lets you reach, lift, and rotate the forearm. Both rely on tendons and ligaments that can tear or fray over time.

Symptoms and causes of a UCL tear

Common symptoms

  • Pain on the inside of the elbow with throwing
  • Loss of throwing velocity or control
  • A pop felt at the time of injury
  • Numbness or tingling in the ring and small fingers

Common causes

  • Repetitive overhead throwing (pitching)
  • A single high-velocity throw that ruptures the ligament
  • Inadequate rest between throwing seasons
  • Poor pitching mechanics

How we diagnose a UCL tear

You want answers, fast, and we're built to give them. Most patients leave their first LAOSS visit with a clear diagnosis and a written plan, not another referral chain.

Here's what your initial visit for a UCL tear typically looks like:

  • Detailed history: when it started, what makes it better or worse, what you've already tried
  • Focused exam of the shoulder & elbow: range of motion, stability, strength, specific provocation tests
  • On-site imaging at most offices: X-ray for bone, ultrasound or MRI when soft-tissue detail is needed
  • A written plan with options ranging from conservative care to surgical procedures, in plain English

Schedule your evaluation at the LAOSS office nearest you.

How we treat a UCL tear at LAOSS

Once we've confirmed the diagnosis, the next step is matching the right treatment to your situation. We start with the least-invasive option that fits, and escalate only when it doesn't.

Conservative care
Step 1

Conservative care first

Non-surgical options designed to relieve pain, restore movement, and avoid the OR when possible.

  • Rest from throwing
  • Physical therapy for the forearm, shoulder, and core
  • Structured return-to-throwing program
  • PRP injection in select partial tears
  • Bracing in select cases
Surgical care
When needed

Surgical options when needed

Minimally invasive and reconstructive procedures performed by board-certified orthopedic surgeons.

  • UCL reconstruction (Tommy John surgery)
  • UCL repair in select tears
  • Ulnar nerve treatment when the nerve is also irritated
  • Staged rehabilitation and return-to-throwing program

Why experience matters.

Why experience matters

Shoulder & elbow care is highly technique-dependent. Volume, training, and judgment together determine the outcome you actually feel six months later.

  • Precise diagnosis from imaging and exam
  • Conservative-first care that avoids unnecessary surgery
  • Surgical technique refined over thousands of cases
  • On-site imaging + coordinated PT through your in-network provider

The LAOSS approach

Our shoulder & elbow specialists move stepwise: start with the least-invasive option that fits your situation, escalate only when it doesn't.

  • Same-day imaging at most offices
  • PT coordinated in your insurance network
  • Board-certified surgeons performing the procedures themselves
  • Direct access to your specialist between visits

Am I a candidate?

If most of these match your situation, an evaluation with a shoulder & elbow specialist is the next step.

You may be

You may be a candidate if

These signs typically point toward an in-person evaluation with a shoulder & elbow specialist.

  • Pain or stiffness in the shoulder & elbow that lasts more than a few days
  • Swelling, instability, or noticeable change in function
  • Symptoms that limit throwing, lifting, sleep, or work
  • Previous treatment that didn't fully resolve the problem
  • Imaging or exam findings that suggest an underlying issue
Evaluation

What evaluation includes

Your first visit is built to give you an answer the same day, not just another referral.

  • Detailed history: onset, mechanism, what makes it better or worse
  • Hands-on exam focused on the affected joint or region
  • On-site imaging at most offices (X-ray, ultrasound)
  • Clear plan with options ranging from conservative to surgical
  • Same-day or next-day scheduling for any follow-up tests

ImportantSeek urgent evaluation for sudden severe pain, numbness, progressive weakness, or any sign of infection (fever, increasing redness or swelling).

Your shoulder & elbow recovery roadmap.

Recovery is rarely a straight line, but a clear plan with measurable milestones makes the path predictable.

    • Activity modification with clear do/don't guidance
    • Ice, elevation, and pain control as needed
    • Gentle range-of-motion within safe limits
    • Follow-up scheduled to track healing
  2. Weeks 2 to 8

    Rehabilitation

    Targeted physical therapy rebuilds strength, mobility, and confidence in the shoulder & elbow.

    • Progressive strengthening and neuromuscular work
    • Manual therapy and soft-tissue treatment
    • Sport- or job-specific movement re-training
    • Coordinated PT through your in-network provider
  3. Months 2+

    Long-term care

    Once function is restored, the focus shifts to keeping you there, and catching any recurrence early.

    • Return-to-activity plan with measured benchmarks
    • Home program tailored to your sport or job
    • Maintenance visits or imaging if symptoms change
    • Direct line back to your specialist if needed
Risks & considerations

What to weigh before you decide.

We talk through the risks and benefits with every patient. Informed consent is a conversation, not a form.

General

General considerations

Every orthopedic intervention carries a small set of standard risks. We screen, prepare, and monitor for these on every patient.

  • Infection (rare with modern technique and prophylaxis)
  • Bleeding or bruising at the treatment site
  • Reaction to anesthesia or medications
  • Need for additional procedures in some cases
Specific

Shoulder and elbow considerations

Some risks are tied to the structures we're treating in the shoulder & elbow. We discuss these in detail at your visit so you can weigh them against the benefits.

  • Temporary stiffness or weakness during recovery
  • Incomplete pain relief in a small percentage of cases
  • Nerve or vessel irritation near the treatment area
  • Need for follow-up therapy to fully restore function
