Rotator Cuff Tears: Symptoms, Causes & Treatment
Shoulder pain can make even simple daily activities feel impossible. Among the most common causes is a rotator cuff tear — an injury that affects mobility, sleep, and quality of life. Recognising it early is the first step toward recovery.
What Is a Rotator Cuff Tear?
The shoulder is a ball-and-socket joint. The rotator cuff is a group of four muscles and their associated tendons that surround this joint, keeping the head of the upper arm bone firmly within the shallow socket of the shoulder.
A rotator cuff injury occurs when these tendons become inflamed or damaged. It is important to distinguish a tear from a strain: a strain involves the muscle or tendon being overstretched, while a tear means the tendon itself is partially or completely separated from the bone.
Causes of Rotator Cuff Tears
Most rotator cuff tears fall into one of two categories — sudden injury or gradual wear and tear.
- —Age-related degeneration — Blood supply to the rotator cuff tendons decreases with age, slowing the body’s natural repair process and making tendons more prone to tearing.
- —Sports injuries — Athletes who repeatedly perform overhead arm movements — such as tennis players, baseball pitchers, and swimmers — face a higher risk.
- —Heavy lifting or repetitive motion — Jobs or activities involving constant lifting or overhead work can gradually wear down the tendon.
- —Accidents or trauma — Falling on an outstretched arm or lifting a heavy object with a sudden jerking motion can cause an immediate tear.
Symptoms of a Rotator Cuff Tear
Recognising the problem early can prevent further damage. Symptoms usually develop gradually, though a traumatic injury can cause sudden, severe pain.
- —Aching shoulder pain — A dull pain deep in the shoulder, especially at night or when lying on the affected side.
- —Weakness — Noticeable loss of strength when moving the arm or lifting objects.
- —Restricted motion — Difficulty reaching behind the back, brushing hair, or lifting items overhead.
- —Clicking or cracking — A popping or grinding sensation when moving the shoulder through its range of motion.
Ignoring these symptoms can lead to worsening pain and, eventually, permanent loss of motion.
Types of Rotator Cuff Tear
Orthopaedic specialists classify these injuries based on severity and how they occurred.
Partial Tear
The tendon is damaged but not completely severed. Its attachment to the bone remains at least partially intact.
Full-Thickness Tear
Also known as a complete tear, this occurs when the tendon fully separates from the bone, often leaving a hole in the tendon tissue.
Acute vs Chronic Tear
An acute tear occurs suddenly, typically from a specific accident or lifting injury. A chronic tear develops gradually over time due to ageing or repetitive stress.
How It Is Diagnosed
An orthopaedic specialist will begin with a thorough physical examination — pressing on specific areas of the shoulder to assess tenderness, moving the arm in various directions to measure range of motion, and testing arm strength.
- —X-rays — Useful for identifying bone spurs or other bony changes that may contribute to symptoms.
- —MRI — The most detailed imaging option for assessing soft tissues and confirming the location and extent of a tear.
- —Ultrasound — A practical alternative that can visualise tendon damage in real time during movement.
For patients reviewing health records or insurance claims, rotator cuff injuries are classified using ICD-10 codes. A complete tear of the right shoulder, for example, is documented as M75.121.
Treatment Options
The right treatment depends on age, activity level, and the severity of the tear. Most patients begin with conservative, non-surgical approaches.
Physical Therapy
Physical therapy is the foundation of rotator cuff recovery. A therapist designs a structured rehabilitation programme focused on strengthening the surrounding muscles, improving flexibility, and restoring joint mechanics without placing stress on the torn tendon.
Pain Management
Over-the-counter anti-inflammatory medications such as ibuprofen or naproxen can reduce swelling and ease pain during recovery.
Corticosteroid Injections
If physical therapy and oral medication provide insufficient relief, a corticosteroid injection directly into the shoulder joint can reduce inflammation and allow more effective participation in rehabilitation.
Surgical Repair
When conservative treatment fails — or in the case of a large acute full-thickness tear — arthroscopic surgery may be necessary. During this minimally invasive procedure, the surgeon reattaches the torn tendon to the bone.
Recovery Time
Can a Rotator Cuff Tear Heal Without Surgery?
A completely severed tendon will not reattach to the bone on its own. However, many patients with small partial tears find significant symptom relief without surgery.
While the physical tear may not close, symptoms can improve substantially. With adequate rest, activity modification, and guided physiotherapy, the surrounding muscles can strengthen sufficiently to compensate for the damaged tendon.
That said, leaving a tear unmanaged carries risk — a small tear can enlarge over time, potentially leading to chronic pain and arthritis.
Prevention Tips
- —Warm up properly — Stretch and prepare your shoulders before sport or physical labour.
- —Use correct lifting technique — Keep objects close to your body and avoid jerking heavy items overhead.
- —Strengthen your shoulders — Include exercises targeting the rotator cuff and shoulder blade muscles in your regular fitness routine to maintain joint stability.
When to See a Specialist
Schedule an appointment if you experience any of the following.
- —Shoulder pain that persists for more than a few weeks despite rest.
- —Difficulty sleeping due to pain when lying on the affected side.
- —Noticeable weakness or inability to lift the arm overhead.
- —A sudden injury followed by sharp shoulder pain and loss of motion.
- —A clicking, cracking, or popping sensation accompanied by pain.
