Understanding the warning signs, why tears happen and how they are diagnosed.

If you’re experiencing new or persistent shoulder pain, an appointment with Dr Susan Alexander can help identify the cause and guide you towards the right treatment.

In brief

  • Rotator cuff tears may be traumatic (due to a specific incident) or degenerative (wear and tear over time), each with different symptom patterns.
  • Common symptoms include pain on activity, night pain disturbing sleep, weakness, stiffness and difficulty lifting or rotating the arm.
  • A tear does not always cause symptoms, some rotator cuff tears are found incidentally on imaging.
  • Rotator cuff injury diagnosis involves clinical assessment plus an ultrasound or MRI scan when necessary.
  • Treatment depends on the type of tear, symptom severity and your daily activity needs.

Many patients worry when shoulder pain affects their day-to-day activities, but understanding what’s happening inside the joint is the first step towards feeling better.

What Causes a Cuff Tear? Understanding Injury Types

Rotator cuff tears tend to fall into two broad types, which behave differently and often present with different symptoms and causes.

Traumatic Tears: When a Single Event Leads to Sudden Pain

Some patients describe a clear moment when their rotator cuff injury occurred, such as lifting a heavy object, falling on an outstretched arm, or a forceful twist of the joint.

This kind of injury can produce immediate swelling and pain, weakness and difficulty moving the affected shoulder.

Degenerative Tears: A Gradual Process Over Time

Other tears develop slowly. These are often linked to:

  • Age-related changes in the muscles and tendons
  • Repetitive overhead sports injuries
  • Natural tendon wear
  • Shoulder impingement or chronic inflammation
  • Hormonal changes such as menopause (a risk factor for tendon weakening)

This type of cuff tear may begin subtly, with intermittent discomfort that progresses into more persistent shoulder pain.

Common Symptoms of a Rotator Cuff Tear

Symptoms vary widely. Two people with the same rotator cuff problem may report completely different experiences.

Dr Susan Alexander frequently sees the following common symptoms:

Night Pain and Difficulty Sleeping

Pain when lying on the affected shoulder is one of the most characteristic indicators of a rotator cuff tear. The ache may radiate down the upper arm or towards the shoulder blade, or up into the neck region..

Loss of Strength and Fine Motor Control

Many everyday movements, such as lifting a kettle, washing hair, reaching behind your back, rely on stable rotator cuff muscles.

A tear can lead to noticeable shoulder weakness, affecting fine motor tasks such as fastening buttons on clothing or writing.

Limited Movement, Stiffness and Functional Difficulty

Some patients struggle to raise their arm overhead or rotate it. Stiffness may mimic frozen shoulder, although the causes are different.

Supraspinatus Pain: A Frequent Symptom

The supraspinatus tendon is the most commonly involved tendon in a cuff tear, which can lead to:

  • Pain when lifting the arm sideways
  • A catching or painful arc of movement from shoulder height upwards
  • Difficulty performing tasks above shoulder height

When Symptoms Are Mild or Absent

Interestingly, some people with a cuff tear found on an MRI scan or ultrasound scan have no symptoms at all.

Similarly, a small tear can sometimes be more painful than a large one.

The anatomy of a rotator cuff tear and inflammation patterns vary widely.

Types of Rotator Cuff Tears and Their Typical Presentations

Tears are not all the same. Understanding types helps guide treatment decisions.

Partial-Thickness Tears

These involve only part of the tendon.

Symptoms may include:

  • Localised discomfort
  • Intermittent aching
  • Mild weakness

Full-Thickness Tears

The tendon is torn all the way through. Patients may notice pronounced weakness, difficulty lifting the arm and persistent symptoms.

Massive Tears

Involve multiple tendons or significant retraction. These can cause:

  • Marked loss of function
  • Compensatory shoulder patterns
  • Increased risk of secondary complications, such as stiffness or imbalance in shoulder mechanics
  • Over time, arthritis can develop in the shoulder joint itself, leading to severe debilitating pain, especially at night.

Supraspinatus Pain and Other Tendon-Related Patterns

The supraspinatus is part of a group of muscles, called the rotator cuff muscles, that work in harmony to keep the shoulder stable.

Symptoms linked to supraspinatus involvement often include:

  • Pain when lifting the arm
  • Painful arc during elevation
  • Weakness when reaching outward
  • Aggravation during overhead tasks

These symptoms overlap with rotator cuff tendinitis, tendinopathy shoulder, or early rotator cuff injury, which may or may not progress to a tear.

Rotator Cuff Injury Diagnosis: What to Expect

A careful, thoughtful diagnosis is central to Dr Susan Alexander’s approach.

History and Symptom Analysis

During your consultation, Dr Alexander explores:

  • When symptoms began
  • Whether a single incident or gradual change occurred
  • Which activities aggravate discomfort
  • What matters most to you in daily life and movement

Physical Examination

She will assess:

  • Range of motion
  • Strength across different shoulder muscles
  • Pain patterns
  • Control and coordination of the shoulder joint

These clinical findings often provide the most valuable information.

Diagnosis and Tests: Imaging When Needed

If scans are indicated, Dr Alexander may arrange:

  • Ultrasound scan (useful for viewing tendon movement and integrity)
  • MRI scan (helpful for detailed evaluation of the quality of the muscle bellies, tendons, adjacent structures and associated injuries or complications)

Imaging supports diagnosis but is always interpreted in the context of your symptoms, not in isolation.

Potential Complications of a Cuff Tear

Not every tear leads to complications, but possible issues include:

  • Progressive weakness
  • Increasing stiffness or mimicking frozen shoulder
  • Reduced shoulder mechanics affecting the neck or upper back
  • Difficulty performing routine tasks
  • Ongoing inflammation or pain during activity

These risks highlight the importance of early assessment and appropriate guidance.

How Symptoms Influence Treatment Choices

Treatment is tailored to the individual, not just the tear.

Conservative management may include:

  • Physiotherapy services focused on restoring strength and control
  • Targeted exercises for stability and coordination
  • Posture and movement retraining
  • Activity modification
  • Steroid injections when appropriate for inflammation and pain relief

Surgery is considered when:

  • Symptoms persist despite good non-operative care
  • A larger tear significantly affects daily function
  • There is retraction of the tendon and shrinking of the muscle.

Muscles can be compared to an elastic band stretched between two fixed posts. If the elastic band is cut it will spring away for the post, and will not automatically lengthen back to its original fixation point.

Similarly, once the tendon that attaches the muscle to the tendon is torn, the muscle will pull away from the bone and with disuse, it will eventually turn into fat. Once this has happened, it is no longer possible to repair the tendon.

If surgery is needed, Dr Alexander uses modern orthopaedic techniques, including minimally invasive shoulder surgery where appropriate.

Looking After a Shoulder With a Cuff Tear

Early assessment, understanding your types of symptoms and personalised rehabilitation can help protect the shoulder and improve long-term function.

With the support of an experienced doctor specialising in shoulder care, most people see meaningful improvement, whether through physiotherapy or, when appropriate, rotator cuff surgery.
