Rotator Cuff Tear

Introduction

If you have been told you have a rotator cuff tear — or you have been living with shoulder pain that has now been investigated — you are likely thinking about what comes next. A rotator cuff tear is one of the most common causes of long-standing shoulder pain in adults, particularly after the age of 40. It can affect simple daily activities like reaching for a cup, washing your hair, dressing, or sleeping on the affected side.

The good news is that rotator cuff tears are well understood. There is a clear range of treatment options, from physiotherapy and injections through to keyhole or open surgical repair. The right path depends on the size of the tear, how long it has been there, your age, your activity level, and how much the shoulder is limiting your life.

This guide explains what a rotator cuff tear is, why it happens, how it is diagnosed, the non-surgical and surgical treatment options available, what recovery looks like, and how to care for your shoulder in the long term.

What Is a Rotator Cuff Tear?

The rotator cuff is a group of four muscles and their tendons that surround the shoulder joint. The four muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. Their tendons join together to form a sleeve that wraps over the top of the upper arm bone (the humerus) and attaches it to the shoulder blade (the scapula).

The rotator cuff has two main jobs:

• It holds the ball of the upper arm bone firmly in the shallow socket of the shoulder blade
• It allows you to lift, rotate, and reach with your arm

A rotator cuff tear means that one or more of these tendons has been damaged — either partly torn or completely separated from the bone.

Partial-Thickness Tear

In a partial-thickness tear, the tendon is damaged or frayed but is still attached to the bone. The tendon is thinner and weaker than normal but not fully torn through.

Full-Thickness (Complete) Tear

Acute vs. Degenerative Tears

Doctors also distinguish between two patterns of how the tear happened:

• Acute tears happen suddenly, usually after a fall, a sudden lifting effort, or a shoulder dislocation. The pain is immediate and often severe.
• Degenerative tears develop slowly over time as the tendon weakens with age, wear, and reduced blood supply. Pain often builds gradually and the person may not remember a specific injury.

Degenerative tears are far more common than acute tears, especially in people over 50.

Causes and Risk Factors

Most rotator cuff tears are caused by a combination of wear over time and mechanical stress on the tendon. The supraspinatus tendon is the one most commonly affected because it passes through a narrow space between bones at the top of the shoulder.

Common Causes

• A fall onto an outstretched arm or directly onto the shoulder
• Sudden heavy lifting, especially with the arm overhead or away from the body
• Repetitive overhead activity at work or in sport (painting, plastering, carpentry, throwing, swimming, tennis, badminton, cricket)
• Age-related thinning of the tendon
• Bone spurs (small bony growths) on the underside of the shoulder blade that rub against the tendon
• Shoulder dislocation, which can pull the tendon off the bone

Risk Factors

• Age over 40, with risk rising steeply after 60
• Occupations involving repeated overhead work or heavy lifting
• Overhead sports played at high volume
• Smoking, which reduces blood flow to tendons and impairs healing
• Diabetes, which is associated with weaker tendon tissue
• Family history of rotator cuff problems
• Previous shoulder injury

Rotator cuff tears are uncommon in children and young teenagers. When they do occur in younger people, they are almost always the result of a significant injury such as a sports accident or a shoulder dislocation, rather than wear and tear.

Signs and Symptoms

The pattern of symptoms depends on the size of the tear and whether it came on suddenly or gradually.

Typical symptoms include:

• Pain in the shoulder, often felt over the outer upper arm
• Pain that gets worse when lifting the arm or reaching overhead
• Pain at night, particularly when lying on the affected side
• Weakness when raising or rotating the arm
• Difficulty with everyday actions such as combing hair, fastening a bra, reaching into a back pocket, or putting on a jacket
• A cracking or grating feeling when moving the shoulder

In larger tears, you may find it hard or impossible to lift the arm overhead on your own. Some smaller tears, especially degenerative ones, can be present without much pain at all and are only discovered when a scan is done for another reason.

Diagnosis

A rotator cuff tear is diagnosed through a combination of clinical examination and imaging. If you are reading this, you have probably already had some of these tests.

Clinical Examination

An orthopaedic specialist or shoulder surgeon will:

• Ask about how the symptoms started and how they have progressed
• Check the range of motion in your shoulder, both what you can move yourself and what the doctor can move
• Test the strength of specific muscles using targeted positions (such as the empty-can test, lift-off test, and external rotation tests)
• Look for tenderness around the joint
• Compare the affected shoulder with the other side

Imaging

• X-ray. Does not show tendons directly, but reveals bone spurs, arthritis, calcium deposits, and the position of the humeral head in the socket. A high-riding humeral head can suggest a large, long-standing tear.
• Ultrasound. A quick and dynamic test that can show tendon tears and how the shoulder moves in real time. It depends heavily on the skill of the person performing it.
• MRI. The most detailed test for the rotator cuff. It shows the size and shape of the tear, the quality of the surrounding muscle, and any other shoulder problems such as labral tears or biceps tendon injury. MRI is generally considered the most accurate single test for planning treatment.

The information from these tests is used together with your age, activity level, and goals to decide on a treatment plan.

Non-Surgical Treatment Options

Many rotator cuff tears, particularly partial and small full-thickness degenerative tears, are treated without surgery. The American Academy of Orthopaedic Surgeons (AAOS) clinical practice guidelines support a trial of non-operative care for many patients, with surgery considered when symptoms do not improve or when the tear is large and acute.

Non-surgical care aims to reduce pain, improve the strength and coordination of the surrounding muscles, and restore as much function as possible. Even when the tendon itself does not heal, the shoulder can often work well if the other muscles compensate effectively.

Activity Modification and Rest

Avoiding the specific movements that aggravate the shoulder — particularly repeated overhead reaching or heavy lifting — allows inflammation to settle. This does not mean keeping the arm completely still, which can lead to stiffness.

Medications

Anti-inflammatory medicines such as ibuprofen or naproxen are commonly used to reduce pain and swelling. Paracetamol may be used for pain relief. These medicines should be taken on the advice of a doctor, particularly if you have stomach, kidney, or heart conditions.

Physiotherapy

Physiotherapy is the cornerstone of non-surgical care. A structured programme typically includes:

• Gentle range-of-motion exercises to keep the shoulder mobile
• Strengthening of the remaining intact rotator cuff muscles
• Strengthening of the muscles around the shoulder blade, which support shoulder function
• Posture correction
• Education on how to use the arm safely during daily activities

A meaningful trial of physiotherapy usually lasts at least 6 to 12 weeks.

Corticosteroid Injections

An injection of steroid medication into the space above the rotator cuff (the subacromial space) can reduce inflammation and pain, especially when pain is preventing you from doing rehabilitation exercises. The effect is often temporary — weeks to months — and most guidelines advise against repeated frequent injections because they can weaken the tendon over time.

When Non-Surgical Treatment May Be Enough

Non-surgical care is often considered first when:

• The tear is partial or small
• The tear is degenerative rather than from a sudden injury
• The person is older or less active
• Other health conditions make surgery riskier
• Pain and weakness are mild to moderate

When Surgery May Be Considered

Surgery is usually discussed when non-surgical care has not given enough relief, or when the features of the tear suggest that surgery is more likely to give a good outcome from the start.

An orthopaedic surgeon may recommend a discussion about surgery if:

• The tear is acute and from a clear injury, particularly in younger or more active people
• The tear is large or full-thickness
• Pain or weakness has not improved after 3 to 6 months of structured non-surgical treatment
• The shoulder is significantly limiting work, sleep, or daily life
• You are unable to lift the arm against gravity
• You are otherwise active and want to return to demanding use of the shoulder

The decision is rarely black and white. It is best made through a conversation with the surgeon, looking at imaging together and weighing your personal goals against what the surgery is likely to achieve.

Rotator Cuff Repair Surgery

Rotator cuff repair surgery aims to reattach the torn tendon to the bone of the upper arm so that it can heal back into place. The general principles are similar across techniques: the torn edge of the tendon is identified, the bone surface where the tendon attaches is prepared, and small anchors with attached sutures are placed in the bone. The sutures are then used to pull the tendon down to the bone and hold it there while it heals.

Surgery is performed under general anaesthesia, often combined with a regional nerve block that numbs the shoulder and arm for several hours after the operation. It is usually done as a same-day or short-stay procedure.

Arthroscopic (Keyhole) Repair

Arthroscopic repair is the most common modern approach. The surgeon makes several small incisions, each less than a centimetre long, around the shoulder. A thin camera called an arthroscope is inserted through one of these to give a view inside the joint, and specialised instruments are passed through the others to carry out the repair.

Advantages often cited include smaller scars, less disruption of the surrounding muscles, and a smoother early recovery. Arthroscopy also allows the surgeon to see and treat other problems inside the joint at the same time, such as biceps tendon issues or labral tears.

Mini-Open Repair

In a mini-open repair, the surgeon uses the arthroscope to look inside the joint and treat any associated problems, then makes a small incision (typically 3 to 5 cm) over the shoulder to complete the tendon repair under direct vision. This approach combines features of arthroscopic and traditional open surgery and may be used for certain tear patterns.

Open Repair

Open repair is the traditional technique, in which a longer incision is made over the shoulder and part of the deltoid muscle is moved aside to reach the torn tendon. It is used less often today but may still be chosen for very large or complex tears, or when other shoulder reconstruction is needed at the same time.

Reverse Shoulder Replacement for Massive Tears

In some cases, a rotator cuff tear is so large and long-standing that the tendons cannot be repaired, and the shoulder has developed arthritis as a result. This is sometimes called rotator cuff arthropathy. In these situations, a procedure called reverse total shoulder replacement may be considered. It changes the mechanics of the joint so that the deltoid muscle can lift the arm even without a working rotator cuff. This is a different operation from rotator cuff repair and is generally offered to older patients with severe symptoms.

Preparing for Surgery

If you and your surgeon decide on surgery, preparation usually includes:

• A pre-operative assessment with blood tests, heart and lung checks, and a review of your medications
• Stopping or adjusting blood-thinning medicines as instructed
• Stopping smoking, ideally several weeks before surgery, because smoking reduces tendon healing
• Bringing the shoulder’s movement and the surrounding muscles into the best possible condition with “prehabilitation” physiotherapy
• Arranging help at home for the first few weeks, since you will have one arm in a sling
• Setting up your sleeping area, as many people sleep more comfortably in a recliner or propped up on pillows for the first few weeks

Recovery and Rehabilitation

The First Few Weeks

The arm is held in a sling, often with a small cushion that keeps the shoulder slightly away from the body. Most surgeons recommend wearing the sling for around 4 to 6 weeks, with timing depending on the size of the tear and the surgeon’s protocol. Pain is managed with medication, ice, and rest.

During this early period, you should not actively lift the arm. A physiotherapist may guide gentle passive movements, in which someone else (or your other hand) moves the arm for you.

Restoring Movement

From around 6 weeks, with the surgeon’s approval, active-assisted exercises begin. You start using your own muscles to move the arm, with support. Range of motion gradually improves over the following weeks.

Strengthening

Strengthening exercises usually start around 3 months after surgery, once the tendon has had time to bond to the bone. The programme progresses slowly, with gradually increasing resistance.

Full Recovery

Most people regain useful function of the shoulder by 4 to 6 months. Full strength and the ability to return to demanding activities or sport often take 6 to 12 months. Larger tears, and tears in older tendon tissue, tend to recover more slowly.

Sticking closely to the rehabilitation programme is one of the most important factors in a good outcome. Going too fast can re-tear the tendon; going too slow can lead to stiffness.

Expected Outcomes

Most people who have rotator cuff repair experience significant improvement in pain and a meaningful gain in function. Pain relief is generally the most consistent result. Improvements in strength and movement are also common but may be less complete in larger or older tears.

Outcomes are typically better when:

• The tear is smaller
• The tendon and muscle are still in good condition (not severely thinned or fatty-infiltrated)
• The repair is done before the tear becomes very long-standing
• The patient does not smoke
• Diabetes and other health conditions are well controlled
• Rehabilitation is followed carefully

Re-tearing of the repaired tendon can happen, especially in larger tears or in older patients. Many people who experience some re-tearing still have good pain relief and function, but a small number need further treatment.

Return to Activity

Approximate timelines vary by surgeon and individual progress, but commonly look like this:

• Light desk work: 2 to 4 weeks, often working one-handed at first
• Driving: typically around 6 weeks, once out of the sling and with safe arm control
• Light household activities: 2 to 4 months
• Heavier physical work and most sports: 6 to 9 months
• Overhead sports and contact sports: often 9 to 12 months

Risks and Complications

Rotator cuff surgery is generally safe, but like any operation it carries some risks. Discussing these with your surgeon helps you make an informed decision.

Possible complications include:

• Infection
• Shoulder stiffness, sometimes called frozen shoulder
• Re-tear of the repaired tendon
• Incomplete pain relief or weakness
• Nerve injury, which is uncommon and usually temporary
• Anaesthetic risks
• Problems with the suture anchors, such as loosening (rare)
• Delayed tendon healing, particularly in smokers and people with diabetes

Choosing a surgeon experienced in rotator cuff surgery, and a centre equipped for arthroscopic shoulder work, reduces but does not eliminate these risks.

Living with a Rotator Cuff Tear and Long-Term Shoulder Care

Whether your rotator cuff tear is managed without surgery or repaired, the shoulder benefits from ongoing care. Tendons that have been damaged once are more vulnerable, and the muscles around the shoulder blade play a major role in keeping the joint stable.

Helpful long-term habits include:

• Continuing the strengthening exercises your physiotherapist teaches you, even after formal rehab ends
• Warming up before sport or heavy work
• Avoiding sudden, unsupported heavy lifting overhead
• Paying attention to posture, particularly if you work at a desk or use a phone for long periods
• Stopping smoking, which improves tendon and bone health
• Managing diabetes and general health
• Returning for review if new shoulder pain develops, rather than waiting until function is severely limited

If you have had one rotator cuff problem, your other shoulder is at slightly higher risk over time. The same protective habits apply on both sides.

How to Choose a Surgeon and Treatment Team

Looking for the right team to manage a rotator cuff tear is reasonable and important. Useful things to consider include:

• Whether the surgeon has specific training and regular practice in shoulder surgery (rather than general orthopaedics only)
• How many rotator cuff repairs they perform each year
• Whether they offer arthroscopic techniques and discuss the full range of options, including non-surgical care
• Whether there is an experienced shoulder physiotherapist or rehabilitation team to work with after surgery
• Whether you feel able to ask questions and get clear answers about your specific tear, its size, and the expected outcomes for someone in your situation

It is reasonable to ask for a second opinion before committing to surgery, particularly for larger tears or when the decision between operative and non-operative care is not clear-cut.

Frequently Asked Questions

Does every rotator cuff tear need surgery?

No. Many partial tears and small degenerative tears improve enough with physiotherapy, activity modification, and sometimes injections. Surgery is more often discussed for acute tears in active people, larger full-thickness tears, and tears that have not improved with several months of non-surgical care.

Can a rotator cuff tear heal on its own?

The torn tendon itself does not usually grow back together without surgery. However, many people with rotator cuff tears become much less symptomatic with rehabilitation, because the surrounding muscles take over more of the work and inflammation settles. So while the tear may remain, the shoulder can still function well.

How painful is the recovery from rotator cuff surgery?

Pain is most noticeable in the first few days and is managed with medication, ice, and a regional nerve block that often lasts into the first night. Most people find pain improves significantly within 2 to 3 weeks, although the shoulder remains stiff and limited for longer. Night discomfort is common in the early weeks and many people find it easier to sleep semi-upright.

How long will I need to wear a sling?

Sling use is typically advised for around 4 to 6 weeks, depending on the size of the tear and the surgeon’s protocol. Some larger repairs require longer protection.

When can I drive again after surgery?

Most people are advised not to drive until they are out of the sling, have good control of the arm, and can react safely in an emergency. This is typically around 6 weeks, but can vary.

Will my shoulder ever be as strong as before?

Many people regain very good function after surgery, especially with smaller tears repaired in healthy tendon tissue. Some loss of strength compared to the original shoulder is common, particularly with larger or long-standing tears, but it is often not enough to limit daily life. Athletes returning to high-demand overhead sport may notice a longer recovery and should plan their return carefully with their surgeon and physiotherapist.

What happens if I delay treatment?

Small tears can grow larger over time. If a tear becomes very large and the muscle behind it shrinks and develops fatty changes, repair becomes more difficult and outcomes may be less complete. This does not mean every tear must be operated on quickly — many are safely watched and treated non-operatively — but ongoing assessment matters.

Can I prevent the other shoulder from tearing?

There is no guaranteed way to prevent a rotator cuff tear, but maintaining shoulder strength and flexibility, using good lifting technique, avoiding smoking, and not ignoring early shoulder pain all reduce risk.

Conclusion

A rotator cuff tear is a common and treatable cause of shoulder pain. Many tears settle with structured non-surgical care, while others — particularly larger acute tears or tears that continue to limit life despite physiotherapy — benefit from surgical repair. Modern arthroscopic techniques have made surgery less invasive than in the past, and recovery, while slow, leads to good outcomes for most people who follow their rehabilitation programme.

The most important step is a clear conversation with an orthopaedic specialist who can look at your specific tear, your goals, and your overall health, and help you choose the treatment path that fits your situation. Whether that path is non-surgical or surgical, careful rehabilitation and ongoing shoulder care are what protect your function in the long term.
