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

  • Shoulder arthritis is one of many shoulder & elbow conditions our specialists evaluate every day.
  • Arthritis cannot be reversed, but many patients control symptoms with activity changes, medication, physical therapy, and injections. Shoulder replacement is an option when those are no longer enough.
  • 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 shoulder arthritis?

Shoulder arthritis is the gradual loss of cartilage between the ball and socket of the shoulder, producing pain, stiffness, and reduced range of motion. Symptoms can develop gradually or after a specific injury, so early evaluation matters when function starts to decline.

Shoulder arthritis cannot be reversed, but many patients manage their symptoms well with conservative care: activity changes, anti-inflammatory medication, gentle physical therapy to keep the shoulder moving, and steroid injections for flare-ups. When pain and stiffness keep limiting sleep and daily life despite these measures, shoulder replacement is the next step to consider, and we explain the options discussed below.

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

Watch: Osteoarthritis of the Shoulder

Osteoarthritis, also called degenerative arthritis, is a gradual breakdown of cartilage in the joints. Cartilage is a tough, flexible connective tissue that protects the ends of bones in the joints. Osteoarthritis of the shoulder can severely impact a person's lifestyle.

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 shoulder arthritis

Common symptoms

  • Deep aching pain in the shoulder joint
  • Stiffness, especially when reaching behind the back
  • Grinding or crepitus with motion
  • Night pain that disturbs sleep

Common causes

  • Age-related cartilage wear (osteoarthritis)
  • Old rotator cuff tear (rotator cuff arthropathy)
  • Prior dislocation or fracture
  • Inflammatory arthritis (rheumatoid)

How we diagnose shoulder arthritis

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 shoulder arthritis 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 shoulder arthritis 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.

  • Activity changes to avoid the motions that flare the joint
  • Anti-inflammatory medication or acetaminophen, as your doctor advises
  • Gentle physical therapy to keep the shoulder moving and strong
  • Ice or moist heat for flare-ups
  • Steroid injections into the shoulder joint for flare-ups
Surgical care
When needed

Surgical options when needed

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

  • Total shoulder replacement when the rotator cuff is intact
  • Reverse shoulder replacement when the rotator cuff is torn or badly worn
  • Partial shoulder replacement (hemiarthroplasty) in select cases
  • Arthroscopic cleanout (debridement) for select patients with earlier arthritis
  • Physical therapy after surgery to restore motion and strength

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 walking, 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.

  1. Days 0 to 14

    Right after care

    In the first two weeks we focus on protecting the shoulder & elbow, calming inflammation, and restoring basic motion.

    • Activity modification with clear do/don't guidance
    • Ice 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
