Rotator Cuff Tendonitis

Rotator cuff tendonitis is a condition that occurs when the tendons in the shoulder become irritated or inflamed. It is one of the most common causes of shoulder pain, especially in people who perform repetitive overhead motions. Early treatment can help relieve pain, restore mobility, and prevent more serious rotator cuff injuries.

What Causes Rotator Cuff Tendonitis?

The tendons in your rotator cuff help stabilize your shoulder and allow you to lift and rotate your arm. Overuse, injury, or natural wear and tear can lead to irritation and degeneration, causing pain and limited movement.

The most common causes of rotator cuff tendonitis include:

• Repetitive shoulder movements, such as lifting, painting, or throwing
• Overuse injuries are common in athletes and manual laborers
• Shoulder impingement, where tendons get pinched between the bones of the shoulder – during movement
• Poor posture or improper lifting techniques
• Aging, where the shoulder tendons weaken over time

People over 40 or those with physically demanding jobs are at higher risk of developing rotator cuff tendonitis.

What Are the Symptoms?

Symptoms of rotator cuff inflammation may include:

• A dull, aching pain in the shoulder or upper arm
• Increased pain when lifting or reaching overhead
• Shoulder stiffness or decreased range of motion
• Weakness in the affected arm
• Trouble sleeping due to shoulder discomfort

These signs of rotator cuff tendonitis usually develop gradually and may worsen without proper care.

When Should I See a Specialist About Rotator Cuff Tendonitis?

You should contact a orthopedic surgeon or sports medicine specialist if you experience:

• Shoulder pain lasting more than a few days
• Difficulty lifting or rotating your arm
• Pain that interferes with sleep or daily activity
• Weakness or stiffness that doesn’t improve with rest
• A history of shoulder injuries

Early treatment can prevent serious rotator cuff injuries and reduce the need for surgery.

How Is Rotator Cuff Tendonitis Diagnosed?

To diagnose rotator cuff tendonitis, an orthopedic specialist will:

• Review your medical history and shoulder pain symptoms
• Perform a physical exam to assess strength, motion, and tenderness
• Order imaging tests like X-rays or an MRI to check for tendon damage or shoulder impingement

An early and accurate diagnosis is important for successful rotator cuff injury treatment.

How Is Rotator Cuff Tendonitis Treated?

Most cases of rotator cuff tendonitis are successfully treated without surgery. Your treatment plan may depend on the severity of symptoms and whether there is any damage to the tendons.

Nonsurgical Treatments

Nonoperative treatment is the first step in relieving shoulder pain from tendonitis. Nonoperative options include:

• Rest and limiting overhead activity
• Ice therapy to reduce swelling
• Anti-inflammatory medications (like ibuprofen or naproxen)
• Physical therapy to strengthen the rotator cuff and improve mobility
• Corticosteroid injections to manage more severe inflammation
• Postural correction and ergonomic adjustments

Most people improve significantly within 6 to 12 weeks of nonoperative treatment.

Surgical Treatments

Rotator cuff tendonitis surgery may be considered if:

• Pain and weakness continue after 3 to 6 months of nonoperative care
• You develop a rotator cuff tear

Minimally invasive procedures such as:

• Arthroscopic tendon debridement (removing inflamed or frayed tissue)
• Subacromial decompression (removing bone spurs and reshaping bone) and bursectomy (removing the bursal sac that sits on top of the rotator cuff)
• Rotator cuff repair, if necessary

These outpatient procedures can relieve pressure on the tendons and restore shoulder function.

What Are the Risks of Rotator Cuff Tendonitis Surgery?

Although rotator cuff surgery is safe for most patients, there are potential risks, including:

• Persistent shoulder pain or limited mobility
• Infection
• Shoulder stiffness or frozen shoulder
• Nerve injury (rare)
• Tendon re-injury if post-op instructions aren’t followed

Working with an experienced orthopedic surgeon and following your rehabilitation plan reduces these risks.

What Does Recovery from Rotator Cuff Tendonitis Surgery Involve?

Recovery from rotator cuff surgery includes:

• Immobilization: shoulder sling for protection during the first few weeks
• Physical therapy to maintain mobility and prevent stiffness
• Avoiding strenuous activity or lifting until cleared by your doctor
• Gradual strengthening of the shoulder over time

How Long Does Recovery from Rotator Cuff Tendonitis Surgery Take?

Recovery times can vary depending on the type of surgery:

• Minor procedures: 6 to 12 weeks for daily activities
• Rotator cuff repair: 3 to 6 months for full function

It can take 6 months or more before you can resume sports or heavy work. Staying committed to your rehab program is essential for long-term success. It may take up to 12 months for full recovery.

What Is the Outlook for Rotator Cuff Tendonitis Surgery?

With the right treatment—whether nonoperative or surgical—most patients recover well from rotator cuff tendonitis. Early diagnosis, proper care, and physical therapy offer the best chance for pain relief and full return to normal activity. If surgery is needed, outcomes are excellent when paired with guided rehabilitation.
