Rotator Cuff Injury.
What is the rotator cuff?
The rotator cuff is a group of four muscles and their associated tendons that work together to stabilise and move the shoulder joint. The four muscles — supraspinatus, infraspinatus, teres minor and subscapularis — originate from the scapula and insert onto the humeral head, forming a cuff of tissue that surrounds the shoulder. Their primary function is to compress the humeral head into the glenoid socket — maintaining the ball centred in the socket during arm movement — while simultaneously contributing to specific shoulder movements: supraspinatus initiates abduction, infraspinatus and teres minor produce external rotation, and subscapularis produces internal rotation.
The rotator cuff works in coordination with the larger shoulder muscles — deltoid, pectoralis major, latissimus dorsi — which produce the power of shoulder movement while the cuff provides the dynamic stability that allows that power to be expressed without the humeral head migrating out of the socket.
Types of rotator cuff injury
Rotator cuff injuries exist on a spectrum from mild tendinopathy to complete tendon rupture, and the management differs significantly across this spectrum.
Surgery versus conservative management — what does the evidence say?
This is the question most patients are trying to answer. The evidence is more nuanced than the traditional assumption that full thickness tears require surgery.
Multiple randomised controlled trials comparing surgical repair to physiotherapy for degenerative rotator cuff tears — including those with full thickness tears — have found that the outcomes at one to two years are broadly comparable. A significant proportion of patients with full thickness tears achieve good to excellent functional outcomes with structured physiotherapy alone, without repair surgery. The tears do not reliably heal with conservative management, but many patients achieve functional recovery despite the structural defect, because the remaining rotator cuff and surrounding muscles compensate adequately.
The patients most likely to benefit from surgery are those with traumatic acute tears in younger active patients, those with large to massive tears producing significant functional deficit, and those who have failed an adequate trial of structured physiotherapy. The surgery versus conservative management decision should be made in consultation with an orthopaedic surgeon experienced in shoulder pathology, with physiotherapy assessment informing the discussion.
How can physiotherapy help?
Physiotherapy plays a crucial role in the management of rotator cuff injuries. A physiotherapist can develop an individualised treatment plan that addresses your specific needs and goals. As your symptoms improve, your physiotherapist will progress your treatment to include exercises to improve your range of motion, strength, and stability, with manual therapy techniques to help improve shoulder function. Additionally, your physiotherapist will work with you to correct any underlying movement or postural imbalances that may have contributed to your injury, reducing the risk of future injury.
The rotator cuff rehabilitation approach focuses on three interconnected goals: restoring the compressive force couple that dynamically centres the humeral head during movement, improving the scapular control that creates a stable base for rotator cuff function, and building the neuromuscular patterns that allow the shoulder to function confidently under load.
Rotator cuff strengthening — with specific attention to the external rotators (infraspinatus and teres minor) and subscapularis — is the primary exercise target. Scapular stabiliser rehabilitation — lower trapezius, serratus anterior and middle trapezius — is equally important and is frequently underemphasised in generic shoulder programs. Thoracic mobility work addresses the postural contributors to both subacromial compression and scapular dyskinesis.
Real time ultrasound assists in assessing tendon integrity and retraining deep rotator cuff activation where pain and inhibition have disrupted normal muscle recruitment. Clinical Pilates can improve shoulder stability, flexibility and overall function while reducing re-injury risk, with exercises targeting rotator cuff muscles including shoulder external rotation, scapular retraction and shoulder flexion. Dry needling of the periscapular and rotator cuff musculature assists with pain management and muscle guarding reduction.
For patients who proceed to rotator cuff repair surgery, see our dedicated rotator cuff repair rehabilitation page. For patients whose injury occurred in a workplace or motor vehicle context, WorkCover and CTP funded physiotherapy is available.
Our physiotherapists Bethany Kippen and Emma Cameron both have experience in rotator cuff conditions and shoulder rehabilitation and are members of the Australian Physiotherapy Association.

Types of rotator cuff injury
Rotator cuff injuries exist on a spectrum from mild tendinopathy to complete tendon rupture, and the management differs significantly across this spectrum.
- Rotator cuff tendinopathy — degeneration of the rotator cuff tendon, most commonly the supraspinatus — is the most common rotator cuff pathology and typically develops from repetitive overhead loading, age-related degenerative changes, or sustained compressive loading in the subacromial space. It produces pain with overhead activities and lying on the affected shoulder, with weakness often reflecting pain inhibition rather than structural failure. This is the presentation most amenable to physiotherapy and most likely to resolve without surgical intervention.
- Partial thickness tears involve tearing of part but not all of the tendon fibres. They can be on the bursal surface (top), articular surface (bottom) or within the tendon substance itself, and their significance depends on the depth of tearing relative to the total tendon thickness. Many partial tears are managed conservatively with excellent outcomes.
- Full thickness tears — where the tendon tears completely through its entire width, creating a hole — are more significant. Small and medium full thickness tears can be managed conservatively in many patients with good outcomes, particularly in older adults with lower functional demands. Large and massive tears — involving two or more tendons — are more likely to require surgical repair, particularly in younger active patients, though conservative management remains appropriate for many even in this group.
- Acute traumatic tears from a fall onto an outstretched arm, shoulder dislocation, or heavy lifting force behave differently from degenerative tears and more often warrant surgical assessment in active patients.
