Rotator Cuff Tear

Rotator Cuff Tear

What is a Rotator Cuff Tear?

rotator cuff tear is merely a tear within your shoulder’s rotator cuff tendons. A rotator cuff tear can occur in two ways:

  • trauma, and
  • repeated microtrauma.

Traumatic rotator cuff tears occur quickly or under heavy load, e.g. a fall or lifting a heavyweight. However, the most common cause of a rotator cuff tear is repeated microtrauma, which can occur over several weeks, months or years.

Repeated rotator cuff injury from straining or pinching the rotator cuff tendons will injure the soft tissue resulting in bruising or swelling. Since only a few millimetres are separating your rotator cuff tendons from a bony hood (acromion), the additional swelling causes a quicker impingement, catching or squeezing of the rotator cuff tendons.

What are the Symptoms of a Rotator Cuff Tear?

Your rotator cuff tears may be partial or full-thickness tears. You will notice that your shoulder pain and weakness increases with the severity of your rotator cuff tear. More importantly, it is a reduction in your shoulder function that is important.

Partial rotator cuff tear may only present with mild shoulder pain, clicking during shoulder elevation, and mild shoulder weakness lifting your hand above shoulder height or reaching behind your back.

Full-thickness rotator cuff tear will typically present with severe shoulder pain and an inability to lift your elbow away from your body. However, in some cases, the rotator cuff tear is so severe that a significant number of your pain fibres are torn, which can make them less painful but very weak.

When you have a small rotator cuff tear, you can often still raise your arm with or without pain. Moderate tears are usually very painful, and you’ll have difficulty moving your arm. Most patients can’t sleep due to the relentless pain.  When a massive rotator cuff tear occurs, you may find that you cannot lift your arm at all.

What is the Rotator Cuff?

Your shoulder’s rotator cuff is a major group of four small shoulder muscles that stabilise, control and move your shoulder joint. When your rotator cuff muscles work in isolation, they exhibit rotational motion at the glenohumeral (shoulder) joint, which is why we describe them as the rotator cuff. The four muscles collectively known as the rotator cuff are your subscapularis, supraspinatus, infraspinatus and teres minor muscles.

How is a Rotator Cuff Tear Diagnosed?

Your physiotherapist or sports doctor will suspect a rotator cuff tear based on your clinical history and the findings from a series of clinical tests.

A diagnostic ultrasound scan is the most accurate method to diagnose the size and location of your rotator cuff tear. MRI’s may show a rotator cuff tear but have also missed a tear. X-rays are of little diagnostic value when a rotator cuff tear is suspected.

For specific advice regarding your rotator cuff tear, please consult your trusted shoulder physiotherapist or doctor.

What is the Best Treatment for Rotator Cuff Injury?

Small and medium-sized rotator cuff tears usually heal successfully with appropriate conservative management and rotator cuff physiotherapy treatment. Physiotherapy often is one of the first treatment options suggested by your doctor or shoulder specialist.

If early treatment methods have failed to settle your symptoms or have an added shoulder bursitis, your health professional may recommend a corticosteroid injection. These injections may improve your pain while sleeping or allow you to perform your rotator cuff exercises. Corticosteroid injections are known to weaken your tendons potentially, so your doctor will inform the prescription of a dose.

Unfortunately, more massive rotator cuff tears may require rotator cuff surgery (arthroscopic or open) if physiotherapy treatment fails to assist. Massive rotator cuff tears may require shoulder replacement or reverse shoulder arthroplasty to restore some of your shoulder function. Post-operative physiotherapist guided rehabilitation will be necessary to regain your shoulder function safely.

Early rotator cuff tear treatment is essential. Delay will result in retraction of your rotator cuff tendon, making healing or rotator cuff repair surgery more complex and less successful. The best rotator cuff tear results occur when the rotator cuff injury is fresh.

Rotator Cuff Tear Treatment

Rotator cuff tears are a common problem. Rotator cuff injury deteriorates further if you return to sport or work too quickly – especially if you didn’t complete a thorough rehabilitation program. They are also regularly poorly treated by inexperienced shoulder practitioners.

Your rotator cuff is an essential group of control and stability muscles that maintain the “centralisation” of your shoulder joint. In other words, it keeps the shoulder ball centred over the small socket. This centralisation prevents other shoulder injuries such as rotator cuff impingement or shoulder dislocation.

Researchers have concluded that there are mostly seven stages that need to be covered to rehabilitate rotator cuff tears and prevent recurrence effectively.

These are:

  1. Early Injury Protection: Pain Relief & Anti-inflammatory Tips
  2. Regain Full Shoulder Range of Motion
  3. Restore Scapular Control
  4. Restore Normal Neck-Scapulo-Thoracic-Shoulder Function
  5. Restore Rotator Cuff Strength
  6. Restore High Speed, Power, Proprioception & Agility
  7. Return to Sport or Work

Your physiotherapist will discuss your goals, time frames and training schedules with you to optimise you for a complete return to sport or work.

The perfect outcome will have you performing at full speed, power, agility and function with the added knowledge that a thorough rehabilitation program has minimised your chance of future injury.


There is no specific time frame for when to progress from each rotator cuff treatment stage to the next. Many factors will determine your rotator cuff rehabilitation status during your physiotherapist’s clinical assessment.

In most cases, you’ll find that your physiotherapist will seamlessly progress between the rehabilitation phases as your clinical assessment and function improves. It is also important to note that your physiotherapist must supervise your progression as attempting to move too soon to the next level can lead to re-injury and frustration.

Don’t hesitate to get in touch with your shoulder physiotherapist for more specific advice about your rotator cuff injury.[/vc_column_text]

What about Corticosteroid Injections?

Corticosteroid injections may relieve pain and promote tendon healing. Cortisone’s primary function is to increase blood sugar, suppress your immune system, and aid in fat, protein and carbohydrate metabolism.

There are side effects, and corticosteroid injections should be used cautiously, especially with diabetics. It also decreases bone formation and leaves you vulnerable to future tendon rupture.

Researchers generally find an excellent short-term benefit from corticosteroids, but there are some long-term side effects, which may be less desirable. Some patients report good initial relief before a recurrence of symptoms. As with all medications, please discuss the pros and cons of corticosteroid injection with your doctor.

Rotator Cuff Repair Surgery

Rotator cuff repair surgery for full-thickness and partial-thickness tears that do not heal with physiotherapy is an option. Most shoulder surgeons will recommend at least six weeks of physiotherapy before contemplating rotator cuff repair surgery.

Post-operative physiotherapy rehabilitation is comprehensive and regular for your best outcome. Your post-operative rotator cuff repair recovery commonly takes between six to twelve months.

During rotator cuff repair surgery, your surgeon will attempt to sew your torn tendon back together. The best results occur when the tear is fresh rather than older damage.

Most rotator cuff repairs take approximately six months of rehabilitation to regain as complete as possible range of motion, shoulder strength and function.

It is essential to follow your physiotherapist’s exercise prescription and the surgeon’s post-operative advice. In our experience, about 90% have an excellent outcome at 12 months postoperatively.

As with all surgery, there are associated risks or complications. These can include infection, stiffness, blood clot formation, and nerve injury. The dangers of significant joint stiffness are less than 5%, and the risk of nerve injury is low – approximately 1 in 10000.

Shoulder Replacement Surgery

Some massive rotator cuff tears will be irreparable using a routine rotator cuff repair. In these instances, a total shoulder replacement is an option for you and your surgeon.

Please seek your trusted shoulder physiotherapist or doctor for their specific advice.

Shoulder Treatment

Researchers have discovered that managing your shoulder injury with physiotherapy is usually successful. Typically, you have two options: a non-operative or a surgical approach. Your condition will dictate which option is best for you at this time. Non-operative care is conservative rehabilitation.

If shoulder surgery is required, then your physiotherapist may undertake:

Pre-operative rehabilitation  - either trial a non-operative/conservative treatment approach or condition and prepare your shoulder and body for a surgical procedure.

Post-operative physiotherapy will safely regain your normal range of movement, strength and function.

PhysioWorks physiotherapists have a particular interest and an excellent working relationship with leading shoulder surgeons. Our physiotherapy team provide you with both conservative and post-operative shoulder rehabilitation options. We aim for you to attain the best possible outcome for your shoulder injury.

Acute Injury Signs

Acute Injury Management.

Here are some warning signs that you have an injury. While some injuries are immediately evident, others can creep up slowly and progressively get worse. If you don't pay attention to both types of injuries, chronic problems can develop.

For detailed information on specific injuries, check out the injury by body part section.

Don't Ignore these Injury Warning Signs

Joint Pain

Joint pain, particularly in the knee, ankle, elbow, and wrist joints, should never be ignored. Because these joints are not covered by muscle, pain here is rarely of muscular origin. Joint pain that lasts more than 48 hours requires a professional diagnosis.


If you can elicit pain at a specific point in a bone, muscle, or joint, you may have a significant injury by pressing your finger into it. If the same spot on the other side of the body does not produce the same pain, you should probably see your health professional.  


Nearly all sports or musculoskeletal injuries cause swelling. Swelling is usually quite obvious and can be seen, but occasionally you may feel as though something is swollen or "full" even though it looks normal. Swelling usually goes along with pain, redness and heat.

Reduced Range of Motion

If the swelling isn't obvious, you can usually find it by checking for a reduced range of motion in a joint. If there is significant swelling within a joint, you will lose range of motion. Compare one side of the body with the other to identify major differences. If there are any, you probably have an injury that needs attention.


Compare sides for weakness by performing the same task. One way to tell is to lift the same weight with the right and left sides and look at the result. Or try to place body weight on one leg and then the other. A difference in your ability to support your weight is another suggestion of an injury that requires attention.

Immediate Injury Treatment: Step-by-Step Guidelines

  • Stop the activity immediately.
  • Wrap the injured part in a compression bandage.
  • Apply ice to the injured part (use a bag of crushed ice or a bag of frozen vegetables).
  • Elevate the injured part to reduce swelling.
  • Consult your health practitioner for a proper diagnosis of any serious injury.
  • Rehabilitate your injury under professional guidance.
  • Seek a second opinion if you are not improving.
