Rotator Cuff Tear Arthropathy

Diagnosis is based on:

• History and Physical Examination
• Providers evaluate shoulder range of motion, strength, and pain.
• Special tests assess rotator cuff function and joint stability.

Imaging Studies

• X-rays: Show signs of arthritis, upward migration of the humeral head, joint space narrowing, and bone changes.
• MRI or Ultrasound: Visualize the size and condition of rotator cuff tendons, muscle atrophy, and fluid in the joint.
• CT Scan: Used for preoperative planning, especially for complex shoulder deformity or bone loss.

Non-surgical management may be appropriate for patients with:

• Mild to moderate symptoms
• Low functional demands
• Medical conditions that make surgery high risk

Conservative options include:

Physical Therapy

• Focuses on:
  • Deltoid strengthening
  • Scapular stabilization
  • Improving range of motion
• Can help maintain function and reduce pain.

Activity Modification

• Avoid overhead or strenuous shoulder movements.
• Use the opposite arm for heavy lifting.

Pain Medications

• NSAIDs (e.g., ibuprofen, naproxen) help reduce pain and inflammation.

Corticosteroid Injections

• Delivered directly into, or around, the shoulder joint to relieve pain to help improve function
• May provide temporary relief, especially if pain limits therapy.

Heat/Ice Therapy

• Ice for acute flares and heat for stiffness can improve comfort.

Nonoperative management can be effective in some patients, but may not prevent progression of the disease. If pain worsens or daily function becomes severely limited, surgery may be considered.

Surgery is usually recommended for patients who:

• Have significant pain and limited function
• Have failed conservative treatment
• Are medically fit for surgery

The most common surgical procedure for rotator cuff tear arthropathy is:

Unlike traditional shoulder replacement, which relies on an intact rotator cuff, reverse shoulder replacement changes the mechanics of the shoulder:

• The normal ball-and-socket arrangement is reversed: a metal ball is placed on the shoulder blade (glenoid), and a plastic socket is placed on the upper arm (humerus).
• This design allows the deltoid muscle to lift the arm in place of the damaged rotator cuff.

Benefits of RTSA:

• Pain relief
• Improved shoulder motion and function
• Increased ability to perform daily activities

RTSA is especially effective in elderly patients with poor rotator cuff function and arthritis.

• Debridement and biceps tenotomy: Cleaning the joint and releasing the biceps tendon for pain relief, but doesn’t improve strength.
• Hemiarthroplasty: Replaces only the humeral head; rarely used now due to inferior outcomes compared to RTSA.

Postoperative Recovery (RTSA):

• Hospital stay: Usually 1–2 nights
  • Can be performed on outpatient basis depending on patient medical conditions
• Sling: Worn for 3–6 weeks
• Physical therapy: Begins within the first few weeks, with gradual progression to strengthening
• Return to daily activities: Within 3 months
• Full recovery: 4–6 months

Outcomes:

• Pain relief: Achieved in >90% of patients
• Improved range of motion and function
• Durability: Modern implants last 10–15 years or more
• Complications: Include infection, dislocation, nerve injury, or implant loosening (rare)

While rotator cuff tear arthropathy can’t always be prevented, early management of rotator cuff injuries can help reduce the risk:

• Seek evaluation for shoulder pain lasting more than a few weeks.
• Follow rehabilitation plans after shoulder injuries or surgery.
• Strengthen shoulder and scapular muscles to support joint mechanics.
• Avoid repetitive overhead lifting or overuse, especially with known tendon injury.

Consult your healthcare provider if you experience:

• Persistent or worsening shoulder pain
• Difficulty lifting the arm or performing daily activities
• Night pain affecting sleep
• Weakness or visible deformity in the shoulder
