Rotator Cuff Tears

What is a Rotator Cuff Tear?

A rotator cuff tear occurs when one or more of the tendons that surround the shoulder joint become damaged or detached from the bone. The rotator cuff is a group of four muscles and their tendons that stabilize the shoulder and allow you to lift, rotate, and reach overhead.

When these tendons are injured, patients often experience pain, weakness, and difficulty lifting the arm. Tears can develop gradually from overuse and degeneration or suddenly after trauma, such as a fall or lifting injury.

Rotator cuff tears are among the most common causes of shoulder pain in adults, especially those over age 40 or individuals who perform repetitive overhead activity.

The shoulder is a ball-and-socket joint formed by the humeral head (ball) and the glenoid (socket) of the shoulder blade. The rotator cuff consists of four muscles:

  • Supraspinatus – initiates arm elevation.
  • Infraspinatus – rotates the arm outward.
  • Teres minor – assists with external rotation
  • Subscapularis – rotates the arm inward

These tendons blend together to form a cuff that surrounds the shoulder joint, keeping the ball centered in the socket during motion. When one of these tendons is torn, the shoulder may stop functioning properly, leading to pain, weakness, and mechanical dysfunction.

Rotator cuff tears can result from degenerative wear and tear, acute injury, or a combination of both.

Degenerative (Chronic) Tears

These occur gradually over time as the tendon weakens and frays due to:

  • Repetitive overhead activity (throwing, lifting, painting, etc.).
  • Poor blood supply to the tendon with aging.
  • Bone spurs under the acromion that rub on the tendon.
  • Untreated impingement or chronic inflammation.

Acute (Traumatic) Tears

These occur suddenly after an injury such as:

  • Falling on an outstretched arm.
  • Lifting something heavy with a jerking motion.
  • Shoulder dislocation.

Even a small acute tear can cause significant weakness and should be evaluated promptly.

Common symptoms include:

  • Pain on the outer or front part of the shoulder, often worse at night or when lying on the affected side.
  • Weakness when lifting or rotating the arm.
  • Difficulty reaching overhead or behind the back.
  • Catching, clicking, or grinding with movement.
  • Loss of range of motion or arm fatigue during activity.

Symptoms may develop gradually or suddenly, depending on the nature of the tear.

Diagnosis begins with a thorough history and examination by Dr. José Vega, Cleveland’s trusted orthopedic shoulder specialist.

During the physical exam, Dr. Vega will:

  • Evaluate shoulder strength, flexibility, and motion.
  • Perform specific tests to identify which tendon is involved.
  • Assess for impingement or other associated conditions.

Imaging studies confirm the diagnosis and guide treatment planning:

  • X-rays show bone spurs or changes in shoulder alignment.
  • Ultrasound visualizes tendon continuity and muscle quality.
  • MRI provides detailed imaging of the rotator cuff, labrum, and biceps tendon, and helps distinguish partial from full-thickness tears.

Accurate imaging is essential to determine the tear’s size, retraction, and tissue quality—factors that influence whether nonsurgical or surgical treatment is most appropriate.

Yes—many partial or degenerative tears can be managed successfully with a comprehensive nonsurgical program focused on reducing pain and restoring function.

Physical Therapy

  • Strengthens the rotator cuff and scapular stabilizers.
  • Improves shoulder mechanics and posture.
  • Restores motion through stretching and progressive resistance exercises.

Medications and Injections

  • NSAIDs reduce inflammation and pain.
  • Corticosteroid injections can relieve pain temporarily and allow more effective rehabilitation.
  • Biologic injections, such as platelet-rich plasma (PRP), may be considered in select cases.

Activity Modification

Avoiding heavy lifting, repetitive overhead work, or painful motions helps prevent further tendon injury.

Many patients achieve lasting improvement with dedicated therapy, though complete tears or persistent weakness often require surgical repair.

Surgery is typically recommended when:

  • The tear is full-thickness or retracted.
  • Pain and weakness persist after 3–6 months of therapy.
  • The patient is young, active, or relies on shoulder strength for work or sport.
  • There is a traumatic tear causing sudden loss of function.

Arthroscopic Rotator Cuff Repair

  • The most common and least invasive technique.
  • Performed through small incisions using a camera and instruments.
  • Torn tendon edges are reattached to bone using sutures and small anchors.
  • Allows excellent visualization, minimal scarring, and faster recovery of motion.

Open or Mini-Open Repair

  • Used for large, complex, or revision cases.
  • Provides direct access for extensive reconstruction or tendon transfers if necessary.

Reverse Shoulder Replacement

  • Considered for massive irreparable tears with arthritis or pseudoparalysis (inability to lift the arm).
  • Uses a special prosthesis that shifts the center of rotation to restore function without relying on the rotator cuff.

  • Sling protection: Typically for 4–6 weeks.
  • Physical therapy: Begins soon after surgery to restore gentle motion, followed by progressive strengthening.
  • Return to activity:
    • Light work or desk duties: 4–6 weeks.
    • Moderate activity: 3 months.
    • Full strength and sport participation: 6–9 months, depending on the tear size and healing.

Adherence to postoperative rehabilitation is crucial for optimal outcomes and tendon healing.

While age-related degeneration can’t always be avoided, certain habits help protect your shoulders:

  • Maintain strong rotator cuff and scapular muscles through regular exercise.
  • Warm up properly before sports or lifting.
  • Avoid repetitive overhead strain without rest.
  • Address shoulder pain early to prevent progression from inflammation to a tear.

Rotator cuff tears are a leading cause of shoulder pain and weakness but are highly treatable. With personalized care—from targeted physical therapy to advanced arthroscopic repair—patients can expect restored strength and function. If you’re experiencing shoulder pain, night discomfort, or difficulty lifting your arm, contact Dr. José Vega’s office in Cleveland to schedule an evaluation and develop a tailored treatment plan.
