The rotator cuff is a group of four muscles and tendons that help move and stabilise the shoulder.
These tendons can become damaged in two broad ways: they may tear suddenly after an injury, or they may gradually weaken and develop a tear over time.
A traumatic tear happens suddenly, usually after an injury such as a fall, lifting something heavy or a sports injury. It may cause sudden pain and weakness, particularly if you were previously using the shoulder normally.
A degenerative tear develops gradually as the tendon becomes weaker over time. It may occur without a single memorable injury and can sometimes be present without causing any symptoms.
The distinction is important because the treatment approach may be different. A sudden tear in an otherwise healthy tendon, particularly when it causes significant weakness, may require earlier consideration of surgery. A degenerative tear can often be managed initially with exercise-based rehabilitation and other non-surgical treatments, depending on the symptoms and the patient's functional needs.
Common symptoms include:
Shoulder pain, particularly when lifting the arm
Pain at night
Difficulty reaching overhead
Weakness of the arm
Difficulty dressing, grooming or performing household activities
Difficulty with work or sports
Diagnosis begins with understanding how the symptoms started and examining the shoulder. X-rays can assess the bones and the condition of the shoulder joint. Ultrasound or MRI may be used to examine the tendons and understand the size and extent of the tear, the quality of the tendon and the condition of the surrounding muscles.
The scan is interpreted together with your symptoms and examination findings rather than being considered on its own.
Treatment depends on whether the tear is related to a recent injury or has developed gradually, as well as the patient's age, symptoms, weakness, activity level, tendon condition and expectations.
Non-surgical treatment may include activity modification, exercises to improve shoulder movement and strength, medication when appropriate and, in selected patients, injections.
Surgery may be considered when there is significant weakness, persistent pain or functional limitation despite appropriate non-surgical treatment, or when a significant tear has occurred suddenly after an injury. The decision is individual and is not based on the MRI report alone.
This depends on the type of tear. Some patients, particularly those with gradually developing tears, can remain comfortable and function well with appropriate rehabilitation without surgery.
However, some tears may become larger over time, and the muscles around the shoulder can gradually lose strength and develop changes that may make a later repair more difficult. This is one reason why a significant tear causing persistent weakness—particularly after a recent injury—should be assessed rather than simply ignored.
Surgery may be considered when:
A significant tear occurs suddenly after an injury
There is substantial or persistent weakness
Pain or functional limitation continues despite appropriate non-surgical treatment
The patient has high functional or sporting demands
The tear has features suggesting that delaying treatment may make later repair more difficult
The decision also depends on the size and location of the tear, the quality of the tendon and muscles, and the patient's overall health and goals.
Not necessarily. A rotator cuff tear seen on an MRI does not automatically mean that surgery is required. Some tears cause little or no symptoms, while others cause significant pain or weakness. Your symptoms, examination, the way the tear occurred, the condition of the tendon and your functional needs all need to be considered before deciding on treatment.
For some patients, structured rehabilitation can provide good pain relief and improve shoulder function. For others—particularly those with a significant recent tear and marked weakness—surgical repair may be more appropriate.
The timeline depends on whether the tear is being treated without surgery or has been repaired surgically.
With non-surgical treatment, improvement is gradual with rehabilitation. Many patients can continue their normal daily activities while modifying movements that cause pain. Recovery may take several weeks to a few months, depending on the severity of symptoms and the demands placed on the shoulder.
After rotator cuff repair, recovery is considerably slower because the repaired tendon needs time to heal. Light daily activities are gradually resumed during the first few weeks, while unrestricted use of the arm usually takes several months. A complete recovery commonly takes 6–9 months or longer, particularly after larger or more complex tears.
The timing depends greatly on the type of work you do.
After non-surgical treatment, people with desk-based or light work may continue working or return relatively quickly, while jobs involving frequent lifting, overhead activity or heavy physical work may require modification until pain and strength improve.
After rotator cuff repair, desk-based work may be possible within 2–6 weeks, depending on comfort and the arm involved. Work involving lifting, pushing, pulling or repetitive overhead activity generally requires a longer period of rehabilitation and may take 3–6 months or longer before a full return to previous duties.
The time required can be considerably longer for physically demanding occupations. Studies of rotator cuff repair show that work intensity is an important factor in recovery and return to previous work.
Return to sports depends on the size and type of tear, the treatment performed, the sport and the progress of rehabilitation.
With non-surgical treatment, low-impact activities can usually be resumed as symptoms improve. Activities involving lifting, throwing, serving or repetitive overhead movements should be reintroduced gradually once pain and shoulder strength have improved.
After rotator cuff repair, return to sports is much more gradual. Strengthening progresses over several months, followed by sport-specific training. Return to unrestricted sports is usually considered around 6 months or later, and overhead or throwing sports may require 6–9 months or longer. Return should be based on adequate movement, strength, shoulder control and sport-specific function rather than time alone.
You should seek an orthopaedic assessment if you develop persistent shoulder pain, weakness or difficulty using your arm, particularly if these symptoms interfere with your daily activities, work or sleep.
Assessment is particularly important if your symptoms started suddenly after a fall, lifting injury or sports injury, especially when you have noticeable weakness or difficulty lifting the arm. A sudden injury can sometimes cause a significant tear that may benefit from earlier treatment.
You should also seek assessment if you already know that you have a rotator cuff tear and your pain or weakness is getting worse, or if your symptoms are not improving with appropriate non-surgical treatment.
An orthopaedic assessment does not necessarily mean that you will need surgery. The aim is to understand the cause of your symptoms, assess the condition of the tendon and discuss whether rehabilitation, other non-surgical treatments or surgery would be most appropriate for you.
