Rotator Cuff Tear Arthropathy

The shoulder is one of the most complex and mobile joints in the body, making it vulnerable to injury and wear over time. This article will explain what rotator cuff tear arthropathy is, its causes, risk factors, symptoms, and stages.

If you are experiencing ongoing shoulder pain or limited motion, fellowship-trained shoulder and sports medicine surgeon Dr. Benjamin Szerlip in Austin and Georgetown, Texas, can help. Schedule an appointment today to explore the best treatment options tailored to your specific needs.

Topic at a Glance

Rotator cuff tear arthropathy is a form of shoulder arthritis that develops after a large or irreparable rotator cuff tear.
Common symptoms include shoulder pain, weakness, limited range of motion, grinding sensations, and difficulty performing everyday activities.
Risk factors include age, previous rotator cuff injuries, repetitive overhead activities, prior shoulder surgery, and degenerative joint changes.
Treatment options range from physical therapy, medications, and injections to surgical procedures such as reverse total shoulder replacement.

What Patients Are Saying

“After a bad fall from a ladder and seeing two other doctors, I was referred to Dr. Szerlip. He was able to repair the breaks in my arm and shoulder. Four months post surgery and I have full use of my arm and shoulder. THANK YOU DR. SZERLIP!!” — Patricia J.

What is Rotator Cuff Tear Arthropathy?

Rotator cuff tear arthropathy is a condition that results from a large rotator cuff tear. Over time, the damage results in a degenerative form of shoulder arthritis.

In a normal shoulder joint, the rotator cuff stabilizes the humeral head (upper arm bone) within the shoulder blade socket. If the rotator cuff suffers an irreparable tear, it will lead to joint instability and cartilage wear.

What Causes Rotator Cuff Tear Arthropathy?

Rotator cuff tear arthropathy is often caused by the following:

Massive rotator cuff tears that remain untreated.
Age-related degeneration of the rotator cuff tendons and cartilage.
Chronic shoulder pain that forces abnormal shoulder motion and leads to joint damage.
Repetitive stress on the rotator cuff muscles weakens them over time.

The rotator cuff muscles normally balance and stabilize the shoulder. When they are damaged, the humeral head drifts upward, causing it to rub on the acromion of the shoulder blade. This can cause severe pain and wear in the shoulder joint.

Risk Factors For Rotator Cuff Tear Arthropathy

Several factors can increase the likelihood of developing cuff tear arthropathy, including the following:

Age: Most common in patients over 60 due to natural tendon weakening.
History of rotator cuff tears: Prior injuries or partial tears that worsen over time.
Repetitive overhead activity: Athletes and workers who lift or throw frequently.
Previous shoulder surgery: Some patients may experience complications after repair attempts.
Genetics: A family history of degenerative joint disease.

What Are the Symptoms of Rotator Cuff Tear Arthropathy?

The symptoms can vary, but often include:

Severe shoulder pain, especially during activity or at night.
Weakness or inability to lift the arm overhead.
Reduced shoulder function and range of motion.
Grinding or clicking sounds when moving the shoulder.
Progressive stiffness as arthritis develops.

As the condition worsens, daily activities like dressing, reaching overhead, or carrying groceries may become difficult.

What Are the Stages of Rotator Cuff Tear Arthropathy?

Rotator cuff tear arthropathy is often diagnosed using the Hamada Classification. The following stages track the movement of the humeral head in the joint:

Stage 1: The shoulder joint remains normal despite the torn rotator cuff. The gap between the top of the arm bone and the shoulder blade is normal (6mm or more).
Stage 2: The arm bone has now moved upward, reducing the space to 5 mm or less.
Stage 3: The space is 5mm or less, but now the arm bone rubs directly against the undersurface of the shoulder’s bone arch (acromion).
Stage 4: The ball-and-socket joint (glenohumeral joint) is showing signs of arthritis.
- Stage 4a: Signs of arthritis without contact between the arm bone and the acromion.
- Stage 4b: Signs of arthritis with contact between the arm bone and the acromion.
Stage 5: This is the most advanced stage. The condition has progressed to the point of total structural collapse of the humeral head (bone necrosis).

Diagnosing Rotator Cuff Tear Arthropathy

Diagnosis typically involves the following tests:

Physical exam: Your doctor will perform tests to evaluate strength, motion, and areas of pain.
Imaging tests: X-rays reveal arthritis and bone changes to classify the condition stage. MRI scans evaluate the integrity of the rotator cuff tendons and muscles.

A fellowship-trained surgeon like Dr. Szerlip will use these tools to determine the best form of treatment.

Treatment Options for Rotator Cuff Tear Arthropathy

Treatment depends on the severity of the tear and arthritis:

Non-Surgical Options

Physical therapy: Exercises are given to maintain mobility and strengthen surrounding muscles to support the joint.
Medications: Non-steroidal anti-inflammatory drugs can be given for pain and swelling.
Steroid injections: These can be given in the subacromial space for inflamed tissues.
Activity modification: You will be encouraged to avoid movements that worsen symptoms.

Surgical Options

When non-surgical care fails, surgery may be considered:

Rotator cuff repair: Suitable for some large but repairable tears.
Partial procedures: Debridement or smoothing roughened surfaces can help relieve pain.
Reverse total shoulder replacement: This specialized procedure is often used for patients with advanced cuff tear arthropathy and an irreparable rotator cuff tear. Reverse shoulder replacement repositions the ball-and-socket to allow the deltoid muscle to compensate for lost rotator cuff function.

What is rotator cuff tear arthropathy?

Rotator cuff tear arthropathy is a condition that occurs when a large or irreparable rotator cuff tear leads to progressive shoulder joint damage and arthritis. Over time, the loss of tendon support causes abnormal joint movement and cartilage wear.

What are the symptoms of rotator cuff tear arthropathy?

Common symptoms include persistent shoulder pain, weakness when lifting the arm, reduced range of motion, grinding or clicking sensations, and increasing stiffness. Symptoms often worsen over time if left untreated.

Who is at risk for developing rotator cuff tear arthropathy?

The condition is most common in adults over 60, individuals with a history of rotator cuff tears, people who perform repetitive overhead activities, and those with previous shoulder injuries or surgeries.

How is rotator cuff tear arthropathy diagnosed?

Diagnosis typically involves a physical examination and imaging studies such as X-rays and MRI scans. These tests help evaluate the condition of the rotator cuff tendons, joint surfaces, and overall shoulder function.

What treatments are available for rotator cuff tear arthropathy?

Treatment may include physical therapy, anti-inflammatory medications, steroid injections, and activity modification. For advanced cases, surgical options such as rotator cuff repair or reverse total shoulder replacement may be recommended.
