Rotator Cuff Injury Treatment Singapore

MBBS (SINGAPORE) MMED (ORTHO) FRCS ED (ORTH)
A rotator cuff tear is a rupture of the sleeve of tendons (rotator cuff) surrounding the ball of your shoulder joint (which comprises a ball and socket joint). The rotator cuff tendons connect muscles of the shoulder blade to the upper arm bone (humerus). These muscles, in turn, provide stability and mobility to your shoulders.
What is a Rotator Cuff Tear?
Rotator cuff tears are extremely common. It is estimated that 21% of the population have such rotator cuff injuries, although the incidence is much higher in the older population.
Another interesting fact is that many people with this type of rotator cuff injury may not be symptomatic at all! In fact, the incidence of asymptomatic rotator cuff tears appears to be higher in older patients.
It is estimated that up to 2/3 of patients in their 60s with rotator cuff injuries may not be symptomatic. The remaining 1/3 of patients seek help because of pain in their shoulders, especially during movements of their arms at their shoulders.
What Causes Rotator Cuff Tears
Rotator cuff tears can develop gradually over time or occur suddenly following an injury. In many cases, patients may not recall a specific event, as changes within the tendon can build up with repeated use or age-related wear. Understanding the underlying causes can help guide appropriate rotator cuff injury treatment and prevent further strain on the shoulder.
Repetitive Overuse
Repeated overhead movements, such as lifting, throwing, or certain occupational tasks, can place ongoing stress on the rotator cuff tendons. Over time, this repeated strain may lead to small areas of damage that can progress into a tear if not addressed.
Degeneration Over Time
As part of the natural ageing process, the tendons in the shoulder may gradually weaken and lose flexibility. Reduced blood supply to the area can also affect how well the tendon maintains and repairs itself, making it more susceptible to tearing even during routine activities.
Acute Injury
A rotator cuff tear can also occur suddenly due to trauma, such as a fall onto the shoulder or lifting something heavy with a jerking motion. In these cases, symptoms often appear immediately and may include pain, weakness, or limited movement in the shoulder.
Shoulder Impingement
In some individuals, the space within the shoulder joint may narrow, causing the rotator cuff tendons to rub against surrounding structures during movement. This repeated friction can gradually irritate and weaken the tendon, increasing the risk of a tear over time.
Postural and Muscle Imbalance
Poor posture or imbalance in shoulder and back muscles can alter how the joint moves. When certain muscles are overused while others are underutilised, the rotator cuff may experience uneven stress, contributing to gradual wear and potential injury.
Here are some other causes of rotator cuff tears:
- Overuse, especially overhead activities
- Wear and tear over time
- Acute injury
Types of Rotator Cuff Tears
Partial-Thickness Rotator Cuff Injury
This injury affects only part of the tendon, causing fraying but not a complete severance. It results from wear or sudden stress, leading to pain and arm weakness when lifting.
Full-Thickness Rotator Cuff Injury
A more severe condition where the tendon is fully ruptured, significantly impairing shoulder function. Symptoms include intense pain, especially at night, and a notable weakness during overhead activities. Surgery may be necessary to mend the tendon.
Acute Rotator Cuff Injury
Typically caused by a sudden, impactful action like a fall or lifting a heavy object, this injury brings immediate, severe shoulder pain. The severity can vary based on the tendon damage extent.
Degenerative Rotator Cuff Injury
Chronic wear due to ageing or repetitive stress leads to these injuries, more frequent in older individuals or those performing repetitive overhead motions. Symptoms, including shoulder weakness and discomfort, gradually worsen with activity.
Tendinopathy
Characterised by chronic tendon overuse, causing swelling and irritation but not full tearing. It presents with pain and restricted movement, often seen in athletes or individuals with repetitive arm use.
Symptoms of Rotator Cuff Tear
Shoulder pain and tenderness
Discomfort and sensitivity in the shoulder, particularly when pressure is applied or when moving the arm in certain positions. The pain often worsens at night, affecting sleep.
Dull ache
A constant, nagging ache in the shoulder is common with rotator cuff injuries. This dull pain typically intensifies with movements that involve lifting the arm or stretching it overhead.
Arm weakness
Damage to the rotator cuff can lead to a noticeable decrease in arm strength, making it challenging to perform routine tasks such as lifting objects or pulling.
Difficulty reaching behind the back or out to the side
Rotator cuff injuries may restrict your ability to move your arm in specific directions, including reaching behind the back or extending the arm out to the side, often due to pain or mechanical limitation in the shoulder.
Decreased range of motion
There is often a reduced ability to move the shoulder through its full range of motion, making it difficult to perform overhead activities or movements across the body.

If a rotator cuff tear is making it harder to carry out everyday activities, it may be time to look more closely at what your shoulder is going through. Simple movements such as reaching overhead, lifting objects, or even getting dressed can become uncomfortable when the tendon is not functioning as it should.
During a consultation, Dr Bryan Tan will assess your symptoms, range of movement, and how your shoulder responds to different activities before recommending a suitable plan. Depending on your condition, this may involve non-surgical care or a more structured rotator cuff treatment aimed at improving function and supporting recovery over time.
Treatment Options for Rotator Cuff Tears
Rotator cuff tears can vary in severity, ranging from mild irritation to more significant tendon damage. The approach to rotator cuff treatment depends on factors such as the size of the tear, symptom severity, shoulder function, and individual activity levels.
Many rotator cuff tears can be managed without surgery, particularly when symptoms are mild or the tear is partial. Non-surgical care focuses on reducing pain, improving shoulder movement, and strengthening surrounding muscles to support the joint.
- Rest and activity modification to reduce strain on the shoulder
- Application of cold or warm compresses to help manage discomfort
- Use of anti-inflammatory medication where appropriate to relieve symptoms
- Physiotherapy to restore range of motion and strengthen the shoulder muscles
- Structured exercises to improve stability and coordination
- Injection-based options, such as corticosteroid injections, in selected cases
This form of rotator cuff injury treatment is often introduced progressively, with adjustments made based on how the shoulder responds over time.
Surgery may be considered when symptoms persist despite a period of structured non-surgical care, or when the tear is larger and affects shoulder function more significantly. The procedure typically involves repairing the torn tendon by reattaching it to the bone.
Surgical treatment is usually discussed when pain, weakness, or limited movement continues to affect daily activities. A detailed assessment helps determine whether surgery is appropriate based on the extent of the tear and the individual’s functional needs.
Tips to Prevent Rotator Cuff Tears
Strengthen Shoulder Muscles
Regularly perform exercises that strengthen the shoulder muscles, particularly the rotator cuff and scapular stabilisers. This can help support the shoulder joint and reduce the risk of injuries.
Improve Flexibility
Incorporate stretching into your daily routine to improve the flexibility of the shoulder muscles and tendons. This can help maintain a healthy range of motion and prevent injuries.
Use Proper Techniques
Whether you’re participating in sports or performing physical tasks, using the correct techniques is crucial. Avoid sudden, awkward movements and ensure you use ergonomic practices when lifting or reaching overhead.
Take Breaks
If your activities involve repetitive shoulder movements, take regular breaks to prevent overuse, which is a common cause of rotator cuff injuries.
Warm-Up Properly
Always warm up before engaging in physical activity to prepare the muscles and tendons for the stress of exercise, reducing the likelihood of injury.
Manage Workload
Gradually increase the intensity and duration of any new activity to give your shoulders time to adapt without becoming overstressed.
Seek Professional Guidance
Consult with a physiotherapist or a shoulder specialist for personalised advice on shoulder exercises and injury prevention strategies.
Anatomy of the Shoulder Joint
The shoulder joint is made up of 3 bones: the shoulder blade (scapula), the humeral head and the collar-bone (clavicle).
Movements around the shoulder involve 3 separate articulations: the glenohumeral joint, the acromioclavicular joint and the scapulothoracic articulation. When the arm is raised, the majority of movement occur at the glenohumeral joint and the scapulothoracic articulation.
Four (4) muscles are attached to the scapula and send their respective tendons across the glenohumeral joint and attach to the humerus just beyond the humeral head. These 4 tendons are collectively known as the rotator cuff.
You can think of the muscles as motors and their tendons as pulleys. Contractions of the muscles will hence bring about movement at the joint that their tendons cross.
Additional Questions About Rotator Cuff Injury Treatment
How To Heal A Rotator Cuff Injury Without Surgery
Healing a rotator cuff injury without surgery can be effectively managed with physiotherapy, which includes exercises to restore strength and flexibility to the shoulder. Other non-surgical rotator cuff tear treatment options include rest, ice applications to reduce swelling, and anti-inflammatory medications to manage pain. Corticosteroid injections may also be considered to relieve severe pain. In recent years, PRP (platelet rich plasma) is gaining popularity as a non invasive option to heal rotator cuff tears.
Is a rotator cuff tear serious? When should I visit a doctor?
A rotator cuff tear generally does not heal on its own without proper treatment. If left untreated, a rotator cuff tear can worsen, resulting in significant loss of mobility and arm function.
You should visit a doctor if you experience extreme pain that does not improve with home remedies such as rest, warm compression or over-the-counter inflammatory medications, or if your symptoms interfere with your daily functioning.
How is rotator cuff surgery performed?
The tendon tear almost always occurs at the area where the tendon joins the bone. An analogy would be the “glue” holding the tendon to the bone has weakened and the tendon comes off the bone.
The aim of the surgery is thus to reattach the tendon to the bone. This is done via keyhole surgery or minimally invasive surgery. For a more detailed description of shoulder surgery, please refer to the page on Keyhole Surgery.

There are many ways to repair the tendon tear. A detailed discourse of tendon repairs is beyond the scope of this article. Basically, as tendons are somewhat rubbery in texture, it is easy to pass stitches through the tendon to pull the torn and sometimes retracted tendon back to place.
To hold it fast to the bone so that it can eventually heal up and reattach itself to the bone, it is necessary to use suture anchors. Suture anchors are small implants made of either metal (often titanium) or medical grade plastics.
They measure about 0.5 cm in diameter and 1 cm in length. A hole just big enough to insert the suture anchor is made in the bone the suture anchor is screwed in. The sutures are then passed through the tendon and tightly tied in place, firmly securing the torn tendon to the bone.
These anchors are designed to be permanent and will not cause any problems like rejection or corrosion. They do not need to be removed.
What kind of anaesthesia will I require?
I often do these surgeries under general anaesthesia. An anaesthetist will be present throughout the surgery to not only anaesthetize the patient, but also to monitor the patient throughout the duration of the surgery to ensure safety of the patient. Please read the section on anaesthesia for more information.
Can I return home on the same day as the surgery?
Yes, certainly you can return home on the same day. Many patients, however, find it more convenient to stay overnight. This is because you may be feeling rather drowsy and tired after you wake up from the anaesthesia.
How long will I take to recover?
Full recovery can take anything from 6 months to a year. Physiotherapy is very important after the surgery because patients will always develop temporary stiffness of the shoulder after the surgery. But with physiotherapy, most patients can expect to recover full functionality of the shoulder. For more details about physiotherapy, please refer to the section on Physiotherapy.
Can a rotator cuff tear heal on its own?
A rotator cuff tear typically does not fully heal on its own, especially if it is a complete tear. However, symptoms can often be managed with non-surgical care, and an orthopaedic specialist in Singapore can assess whether this approach is suitable based on your condition.
What movements should I avoid with a rotator cuff tear?
Movements that involve lifting the arm overhead, heavy lifting, or repetitive shoulder use may worsen symptoms. A sports orthopaedic approach can help guide safe modifications to reduce strain during recovery.
How is a rotator cuff tear diagnosed?
Diagnosis usually involves a physical examination to assess movement, strength, and pain patterns, sometimes supported by imaging such as ultrasound or MRI. An orthopaedic doctor will use these findings to confirm the extent of the injury.
Can I continue exercising with a rotator cuff injury?
Some low-impact exercises may still be appropriate, though activities that strain the shoulder should be limited. An orthopaedic specialist can recommend suitable exercises that support recovery without aggravating the injury.
What happens if a rotator cuff tear is left untreated?
An untreated tear may lead to ongoing pain, weakness, and reduced shoulder function over time. An ortho assessment can help determine the potential impact and whether intervention is needed.
When should I consider seeing a specialist?
If shoulder pain persists, worsens, or begins to affect daily activities, it may be appropriate to seek further evaluation. An orthopaedic surgeon in Singapore can assess the condition and discuss suitable management options.
Can rotator cuff injuries recur after treatment?
Recurrence is possible, particularly if the shoulder continues to be exposed to repetitive strain or insufficient recovery time. An ortho specialist in Singapore can advise on preventive strategies and activity adjustments to reduce this risk.
