Shoulder & Elbow Conditions We Treat in Los Angeles

Shoulder and elbow pain can make everyday tasks like reaching, lifting, or even getting dressed difficult. Our LA-based team helps patients understand and overcome the full spectrum of upper extremity conditions through expert diagnosis and individualized care. Whether your symptoms began after a fall, have worsened over time, or seem minor but persistent, our orthopedic shoulder specialists are here to help you move forward with clarity and confidence.

Rotator Cuff & Soft Tissue Condition

We treat a wide range of soft tissue injuries, including rotator cuff tears, tendinitis, bursitis, SLAP (labral) tears, and muscle or tendon strains. These conditions often cause pain, weakness, or limited motion, and they may worsen without care. Our specialists provide targeted treatment to restore strength and shoulder stability.

Joint & Bone Conditions

Our specialists diagnose and treat joint and bone conditions like osteoarthritis and frozen shoulder, as well as fractures of the shoulder, humerus, or elbow. We also manage elbow osteochondritis dissecans (OCD), a joint disorder often seen in younger patients. Personalized care can help reduce pain and restore joint function.

Instability & Overuse Conditions

Repetitive motion or past injuries can lead to chronic shoulder or elbow issues. At LAOSS, we treat shoulder dislocations, chronic joint instability, tennis elbow, golfer’s elbow, and throwing injuries common in athletes and active adults. Our care focuses on relieving pain, restoring control, and preventing future flare-ups or injuries.

Nerve & Compression Conditions

Nerve-related pain in the shoulder or elbow can disrupt daily life. We treat conditions like cubital tunnel syndrome, nerve entrapments, and referred shoulder pain linked to neck or spinal nerve issues. Our specialists pinpoint the source and provide targeted relief to improve function, comfort, and long-term nerve health.

Traumatic Injuries

Accidents, falls, and sports injuries can lead to sudden, severe damage. LAOSS treats acute fractures and dislocations, complex ligament tears, and both sports-related and work-related injuries to the shoulder and elbow. We provide prompt evaluation and expert care to stabilize injuries, support healing, and restore full function.

Our experienced shoulder and elbow team specializes in both surgical and non-surgical solutions. We take a comprehensive approach, offering advanced imaging, conservative therapies, and surgical expertise to help you return to strength and function as safely and quickly as possible.

Expert Diagnosis for Shoulder & Elbow Conditions in Greater LA

Shoulder and elbow pain can disrupt every part of life, and without the right diagnosis, these issues often get worse. Our goal is to help our patients get clear answers, fast.

 

The orthopedic shoulder and elbow specialists at LAOSS are trained to evaluate the full spectrum of upper extremity conditions. Your diagnostic visit is designed to be thorough, supportive, and streamlined. In most cases, you’ll leave your first appointment with a clear understanding of your condition and a personalized plan for next steps.

 

Here’s what to expect during your evaluation:

 

  • We start by discussing your symptoms, including when they began, what triggers them, how they affect your daily life, and any past injuries or conditions that may play a role.
  • Your provider will perform a physical evaluation and evaluate your range of motion, strength, stability, swelling, alignment, and areas of tenderness to identify potential causes and rule out others.
  • Most LAOSS locations offer in-office X-rays to evaluate bones and joints during your visit. If needed, we’ll coordinate an MRI, CT scan, or ultrasound for more complex soft tissue or nerve-related issues.
  • We may do functional movement testing to see how your shoulder or elbow performs during common motions, such as lifting, reaching, or throwing, to better understand how your condition impacts function.

 

Following your diagnosis, we’ll guide you toward the best course of care, whether that includes physical therapy, injections, minimally invasive arthroscopy, rotator cuff repair, or fracture care.

Advanced Shoulder & Elbow Treatments in Greater LA

Our premier team of surgeons at Los Angeles Orthopedic Surgery Specialists understands how frustrating shoulder pain can be, and we offer the most advanced shoulder surgery techniques to help you get back to your life quickly. A nonsurgical approach is typically the first step in treating shoulder issues.

Bracing & Immobilization

For certain shoulder and elbow injuries, bracing and immobilization provide essential support during healing. At LAOSS, we use custom-fitted braces and slings to protect injured joints, reduce pain, and prevent further damage. This approach allows tissues to heal properly while preparing patients for physical therapy or advanced treatment if needed.

Steroid Injections

Steroid injections can provide powerful, targeted relief for shoulder and elbow pain caused by inflammation, arthritis, or tendon irritation. Our specialists use image-guided techniques to deliver medication directly to the source of your pain, reducing discomfort and swelling while supporting mobility and function. Injections are often used as part of a broader treatment plan.

Physical Therapy

Physical therapy plays a vital role in recovering from shoulder and elbow injuries. We partner with skilled therapists to design personalized exercise and mobility programs. Therapy helps reduce pain, restore range of motion, rebuild strength, and prevent future injury, supporting long-term recovery and improved daily function.

PRP Injections

Platelet-Rich Plasma (PRP) injections use your body’s own healing cells to promote tissue repair and reduce inflammation in the shoulder and elbow. At LAOSS, our specialists offer PRP as a regenerative treatment option for tendon, ligament, and joint conditions, supporting recovery, enhancing mobility, and helping patients return to activity

In the event your pain and function doesn’t improve after trying nonsurgical treatments, our specialists may recommend surgery. Surgery techniques can vary based on what type of injury or condition you have, but most involve minimally invasive techniques like arthroscopic surgery. The leading surgeons on our team are experts in understanding the complexities of the shoulder and elbow, allowing them to offer high-level care.

Shoulder or Elbow Arthroscopy

With arthroscopy, your surgeon uses quarter-inch incisions to insert tools that help them view your joint from within as they perform your procedure. This approach minimizes bleeding, tissue damage, pain, and risk of infections after surgery. Arthroscopy can treat shoulder and elbow problems and have you released from care on the same-day.

Rotator Cuff Repair

When rotator cuff tears limit strength and movement, rotator cuff repair surgery can restore stability and function. Our orthopedic surgeons specialize in minimally invasive arthroscopic techniques whenever possible, reducing recovery time and scarring while providing lasting relief, helping patients return to work, sports, and daily activities with confidence.

Labral Repair & Stabilization

Labral repair and stabilization address shoulder injuries such as SLAP tears and recurrent dislocations. Our specialists use advanced arthroscopic techniques to reattach or tighten the labrum, restoring joint stability and reducing pain. This procedure helps patients regain confidence in shoulder movement and return to active, pain-free living.

Fracture Fixation

For complex breaks of the shoulder, humerus, or elbow, fracture fixation ensures bones heal in proper alignment. The surgeons at LAOSS use advanced techniques, including plates, screws, or pins when necessary, to stabilize fractures, reduce pain, and restore mobility. 

Elbow Ligament Reconstruction (Tommy John surgery)

Elbow ligament reconstruction, also known as a Tommy John surgery, restores stability when the ulnar collateral ligament (UCL) is torn, often from repetitive throwing. Our surgeons perform precise reconstruction using graft tissue, helping athletes and active patients regain strength, protect long-term elbow health, and safely return to performance.

Shoulder Replacement (partial or total)

When arthritis or severe joint damage limits shoulder movement and causes persistent pain, shoulder replacement surgery may be the best option. At LAOSS, our surgeons perform both partial and total replacements, using advanced implants to restore mobility and function.

Revision Surgery

When prior shoulder or elbow procedures fail to relieve pain or restore function, revision surgery may be necessary. At LAOSS, our doctors evaluate complex cases and perform corrective procedures to address complications, improve joint stability, and optimize outcomes, providing patients with renewed confidence, mobility, and long-term orthopedic relief.

Normally, physical therapy starts about a week after your surgery. This helps you build strength so you can return to normal activities. 

When it comes to treatment, our patients experience the difference of individualized surgical planning, coordinated physical therapy, and direct follow-up with their orthopedic specialist in a supportive, compassionate healthcare space. Schedule your appointment today and experience top-level care at LAOSS.

Greater LA’s Leading Shoulder & Elbow Doctors Since 2006

How do I know if my shoulder pain is serious?

Shoulder pain may be serious if it lasts more than a few days, limits your range of motion, or interferes with daily activities. Warning signs include sudden weakness, swelling, visible deformity, or pain that worsens at night. Persistent pain after an injury or overuse should be evaluated to rule out rotator cuff tears, arthritis, or fractures.

For shoulder or elbow pain, the best specialist to see is an orthopedic doctor, particularly one with expertise in the upper extremities. Orthopedic specialists are trained to diagnose and treat conditions involving bones, joints, ligaments, tendons, and muscles. They can recommend non-surgical care, physical therapy, injections, or surgery if necessary, depending on your condition.

Shoulder pain when lifting your arm overhead may result from rotator cuff irritation, tendonitis, bursitis, impingement syndrome, or a labral tear. These conditions cause inflammation or pinching of soft tissues in the joint, leading to pain and limited motion. In some cases, arthritis or instability may be involved. Persistent discomfort should be evaluated to prevent worsening an injury.

Surgery is not always required for shoulder or elbow pain. Many conditions improve with non-surgical treatments such as rest, physical therapy, bracing, anti-inflammatory medications, or targeted injections. Surgery is usually considered when conservative care does not relieve symptoms, or if there is a severe injury such as a rotator cuff tear, fracture, or joint instability.
