The rotator cuff is a group of four strong tendons around the shoulder that help lift and rotate the arm and keep the shoulder joint stable.
These tendons can become damaged or torn because of an injury, repeated use, or gradual wear over time. A significant tear can cause shoulder pain, weakness and difficulty raising the arm.
When appropriate, rotator cuff repair is an operation to reattach the torn tendon to the bone and allow it to heal.
The operation can be performed using arthroscopic surgery through small cuts or through a mini-open approach using a slightly larger cut. Both methods are well-established ways of repairing a torn rotator cuff.
Not every rotator cuff tear needs surgery.
Many patients can initially be treated with rest, activity modification, medicines, exercises and physiotherapy. Surgery may be considered when:
Pain continues despite appropriate non-surgical treatment
The shoulder remains weak
The tear is causing significant difficulty with daily activities
There is a significant tear following an injury
The patient has difficulty raising the arm
The tear is likely to benefit from repair based on its size, location and condition
The patient's work or sports activities place significant demands on the shoulder
The decision depends on your symptoms, the type and size of the tear, the condition of the tendon and muscle, your age and activity level, and what you want to achieve from treatment.
An MRI or other scan may be used to understand the tear and determine whether it is suitable for repair.
Rotator cuff repair is an operation in which the torn tendon is reattached to the bone from which it has pulled away.
The tendon is brought back to its normal position and held securely with strong stitches. Small devices that sit inside the bone may be used to hold the stitches in place.
The aim is for the tendon to gradually heal back onto the bone and restore the function of the shoulder.
There are two commonly used approaches:
Arthroscopic rotator cuff repair
Arthroscopic repair is performed through small cuts around the shoulder.
A small camera is inserted into the shoulder so that the surgeon can clearly see the tendon and the other structures inside the joint.
Small instruments are then used to prepare the area, bring the torn tendon back to its normal position and secure it with strong stitches.
Additional problems in the shoulder can also be assessed and treated during the same operation when necessary.
Mini-open rotator cuff repair
In a mini-open repair, the surgeon uses a slightly larger cut to reach the torn tendon directly.
The tendon is repaired and securely attached back to the bone using strong stitches and small devices placed in the bone.
Mini-open repair is still an effective and well-established way of repairing a rotator cuff tear.
Both arthroscopic and mini-open repair can provide good improvement in pain, shoulder movement and function.
Studies comparing the two methods have generally found similar results, including similar long-term function and rates of the tendon tearing again.
Arthroscopic surgery uses smaller cuts and allows the surgeon to examine the entire shoulder carefully. Mini-open repair can also provide excellent results and remains a useful option in selected patients.
The choice depends on the type of tear, other problems in the shoulder and the surgeon's assessment and experience.
When the tear is suitable for repair, surgery can:
Reduce shoulder pain
Improve the ability to raise the arm
Improve shoulder strength
Improve shoulder movement
Make everyday activities easier
Help patients return to work and exercise
Help appropriately selected patients return to sports
Improve overall shoulder function and quality of life
Long-term studies have shown that patients can maintain substantial improvements in pain and shoulder function many years after rotator cuff repair.
The aim of surgery is for the tendon to heal back onto the bone.
However, tendon healing depends on several factors, including:
Size and type of the tear
Quality of the tendon
Condition of the shoulder muscles
Age
Smoking
General health
How well the shoulder is protected during the early healing period
Following the recommended rehabilitation programme
A tendon can sometimes tear again after repair, particularly when the original tear is large or the tendon and muscles are significantly damaged.
Importantly, a good clinical result is possible even when complete healing is not seen on a scan. The aim of surgery is ultimately to improve pain and shoulder function.
Recovery after rotator cuff repair is gradual because the tendon needs time to heal securely to the bone.
The arm is usually protected in a sling during the early part of recovery. Shoulder movement is then introduced progressively, followed by strengthening exercises.
Recovery generally involves:
Early recovery
Protecting the repaired tendon
Controlling pain and swelling
Gentle shoulder movement as advised
Later recovery
Gradually increasing shoulder movement
Strengthening the shoulder muscles
Improving control and coordination
Gradually returning to normal activities
Final recovery
Returning to heavier activities
Work-specific exercises when needed
Gradual return to sports
The recovery programme is particularly important because the tendon needs time to heal before it can safely tolerate increasing loads.
Rotator cuff recovery takes time.
The shoulder may feel better before the tendon has fully healed, so increasing activity too quickly can put the repair at risk.
Many patients gradually regain useful shoulder function over the first few months, but strength and full recovery can continue to improve for 6–12 months or longer, particularly after larger tears.
The exact recovery time depends on the size of the tear, the quality of the tendon, the type of repair and the patient's rehabilitation.
This depends on the type of work you do.
People with desk-based work may return earlier, while jobs involving lifting, pushing, pulling or repeated overhead activity usually require a longer period of recovery.
Your return to work should be gradual and based on the healing of the tendon and the physical demands of your job.
Return to sports takes longer than return to everyday activities.
The shoulder needs to regain adequate movement, strength and control before demanding activities are resumed.
Activities involving throwing, heavy lifting or repeated overhead movements usually require a longer rehabilitation period.
Many appropriately selected patients can return to sports after successful repair and rehabilitation, although the timing varies depending on the sport and the individual recovery.
Rotator cuff repair is a commonly performed operation, and serious complications are uncommon.
Possible problems include:
Infection
Bleeding
Shoulder stiffness
Continued pain
Weakness
The tendon not healing completely
The tendon tearing again after healing
Problems related to the small devices used to hold the stitches
The need for another operation
Following your surgeon's advice and keeping up with your exercises and physiotherapy can help support a smooth recovery and protect the repair while it heals.
No. Many rotator cuff tears can be managed successfully without surgery. Surgery is considered when the tear is suitable for repair and symptoms such as pain or weakness continue to interfere with the patient's life despite appropriate treatment.
Both techniques can provide good results. Current evidence does not show a consistent important difference in long-term pain, shoulder function or the chance of the tendon tearing again.
Recovery is gradual. The tendon needs several months to heal and shoulder strength can continue to improve for 6–12 months or longer, particularly after larger tears.
Many appropriately selected patients can return to sports after successful healing and rehabilitation. The return should be gradual and depends on the type of sport, the size of the tear and the recovery of shoulder strength and movement.
