The rotator cuff is a group of muscles and tendons that hold the shoulder joint in place and allow a wide range of arm movement. A rotator cuff tear happens when one or more of these tendons becomes partially or completely torn, which can cause pain, weakness, and difficulty lifting or rotating the arm.
If you have shoulder pain, weakness, or difficulty raising your arm, book your shoulder MRI at MVR Diagnostic Clinic to help identify the cause. Read this guide to understand rotator cuff tear causes, symptoms, MRI findings, diagnosis, and treatment options.
Experiencing persistent shoulder pain or weakness?
A shoulder MRI can provide detailed images of the rotator cuff and surrounding soft tissues. Book your MRI at MVR Diagnostic Clinic.
The rotator cuff is made up of four muscles and their tendons, which attach the upper arm bone to the shoulder blade. Together, they help lift and rotate the arm and keep the shoulder joint stable. A tear occurs when one of these tendons is overstretched or torn away from the bone, either partially or completely.
Rotator cuff tears are generally described as:
Tears can also be classified by how they developed, either gradually over time or suddenly as a result of injury.
Rotator cuff tears generally fall into two categories: those caused by gradual wear and those caused by a sudden injury.
Most rotator cuff tears develop gradually as the tendon wears down with age and repetitive use. Reduced blood supply to the tendon over time can also make it more prone to tearing, even without a specific injury.
A sudden tear can occur from a fall onto an outstretched arm, lifting a heavy object abruptly, or a direct blow to the shoulder. Acute tears can happen at any age but are more likely when the tendon is already weakened by wear.
Repeated overhead motion, common in certain sports and occupations such as painting, construction, or throwing sports, can gradually stress the rotator cuff tendons.
Repeated pinching of the rotator cuff tendons between the shoulder bones during arm movement can contribute to tendon damage over time.
Certain factors can increase the likelihood of a rotator cuff tear:
A rotator cuff tear can also occur in people without any obvious risk factors.
Symptoms can vary depending on whether the tear is partial or complete, and whether it developed suddenly or gradually.
Common symptoms include:
With a sudden, acute tear, pain is often immediate and may be accompanied by a snapping sensation at the time of injury. Degenerative tears, on the other hand, often cause symptoms that build up slowly over weeks or months.
Some people can still move their arm, even with a significant rotator cuff tear, because other shoulder muscles can partly compensate. This means that the ability to lift the arm does not rule out a tear.
However, weakness, pain with specific movements, or difficulty with overhead activity should still be evaluated, since the extent of the tear is not always reflected by how much movement remains.
Diagnosis usually begins with a medical history and physical examination. Your doctor may ask about:
During the examination, the doctor may perform specific tests to assess shoulder strength, stability, and range of motion, and to help identify which tendon may be affected.
MRI is one of the most useful imaging tests for evaluating a suspected rotator cuff tear. It provides detailed images of the tendons, muscles, and surrounding soft tissues of the shoulder without using radiation.
MRI can help assess:
For ongoing or unexplained joint pain, our guide on persistent joint pain and when an MRI may help explains when further imaging may be considered.
MRI findings depend on whether the tear is partial or complete.
A partial rotator cuff tear may show:
A full-thickness tear may show:
MRI findings are always interpreted alongside the clinical examination to guide treatment decisions.
A rotator cuff tear may occur together with, or be mistaken for, other shoulder conditions. MRI can help identify associated issues such as:
Degeneration or thickening of a tendon without a complete tear, which can still cause pain and weakness.
Narrowing of the space through which the rotator cuff tendons pass, which can contribute to tendon irritation and damage over time.
Damage to the cartilage ring that helps stabilize the shoulder joint, which can occur alongside rotator cuff injuries.
Inflammation of the fluid-filled sac that cushions the shoulder joint, which can contribute to pain even without a tendon tear.
MRI can show excess fluid within the shoulder joint, which is one reason MRI can be useful when evaluating persistent shoulder pain.
Shoulder pain can have several causes, and rotator cuff tears and frozen shoulder can sometimes be confused with one another.
| Feature | Rotator Cuff Tear | Frozen Shoulder |
|---|---|---|
| Main issue | Torn tendon | Stiffness of the joint capsule |
| Weakness | Common | Less typical |
| Stiffness | Variable | Pronounced, progressive |
| Onset | Sudden or gradual | Usually gradual |
| Pain at night | Common | Common |
| MRI | Shows tendon tear | Shows capsular thickening |
A thorough clinical examination, supported by MRI when needed, can help distinguish between these and other causes of shoulder pain.
Treatment depends on several factors, including:
Treatment generally falls into two broad categories: non-surgical management and surgical repair.
Not every rotator cuff tear requires surgery. Non-surgical treatment may be considered, particularly for smaller or partial tears.
Rotator cuff repair surgery may be considered when:
The decision is individualized and should be discussed with an orthopedic specialist.
Rotator cuff tendons have a limited capacity to heal on their own, particularly once a tear is complete. Partial tears may sometimes improve with rehabilitation and become less symptomatic without surgery.
However, a complete tear does not generally heal back together without surgical repair, although many people manage well with non-surgical treatment despite the tear remaining present on imaging.
Recovery time varies depending on the severity of the tear and the treatment approach. Non-surgical recovery can take several weeks to a few months with consistent physiotherapy.
For people undergoing surgical repair, rehabilitation is typically longer and commonly takes several months, involving a gradual progression from protecting the repair to restoring strength and range of motion.
It depends on the severity of the tear and the type of exercise. Activities involving heavy lifting or repetitive overhead movement may worsen symptoms or risk further injury.
A physiotherapist or orthopedic specialist can recommend exercises appropriate for your specific tear and stage of recovery.
An untreated tear, particularly a complete one, does not generally improve on its own and may gradually worsen over time. This can lead to progressive weakness, reduced shoulder function, and in some cases, further enlargement of the tear.
Chronic untreated tears can also make later surgical repair more complex. This is why persistent shoulder pain or weakness deserves proper assessment rather than being left unaddressed.
MRI may be considered when there is:
Preparation depends on whether contrast is required and the specific MRI protocol. Before the examination, tell the MRI team if you:
If contrast is planned, read our guide on MRI contrast agent safety to understand what to expect.
If you have a larger body size, inform the MRI team when booking your scan so they can provide appropriate guidance based on the available equipment and your individual requirements.
You will usually lie on your back on the MRI table, with the affected shoulder positioned within a dedicated shoulder coil. The scan involves loud knocking or tapping sounds, so hearing protection is generally provided.
It is important to remain still during the examination, as movement can reduce image quality. A shoulder MRI is non-invasive and does not use ionizing radiation.
Seek medical assessment if you experience:
Prompt assessment can help determine whether a rotator cuff tear or another shoulder condition is responsible.
A rotator cuff tear can affect shoulder strength, movement, and daily activities, but many people recover well with the right treatment. While symptoms such as pain and weakness can raise suspicion, they do not confirm the diagnosis on their own.
A clinical examination can assess shoulder strength and stability, while MRI can provide detailed information about the rotator cuff and any associated shoulder injuries.

Shoulder pain, particularly with overhead movement or at night, along with weakness when lifting the arm, are common features of a rotator cuff tear.
Yes. MRI can provide detailed images of the rotator cuff tendons and help identify partial or complete tears, along with associated shoulder conditions.
Yes, in many cases. Other shoulder muscles can partly compensate, so the ability to move the arm does not rule out a tear.
No. Many tears, particularly smaller or partial ones, can be managed with physiotherapy and activity modification. Surgery may be considered for larger tears, significant weakness, or when non-surgical treatment does not help.
Recovery depends on the severity of the tear and treatment approach. Non-surgical recovery can take several weeks to a few months, while recovery after surgical repair commonly takes several months.
Partial tears may improve with rehabilitation. A complete tear does not generally heal back together without surgical repair, although many people manage well with non-surgical treatment.
Not always, especially with smaller or partial tears. However, weakness is a common and important symptom, particularly with larger or complete tears.
