What is rotator cuff injury?
The rotator cuff is a group of four tendons that wrap around the top of the arm bone, powering and stabilising the shoulder. Injuries range from tendon irritation (tendinopathy) to partial and full-thickness tears. In younger people tears usually follow an injury such as a fall; in people over 50 the tendons gradually weaken, and tears can develop with minimal or no trauma. It is one of the most common causes of shoulder pain in adults.
Diagnosis involves an examination testing the strength and movement of each tendon, followed by imaging. Ultrasound is a quick and accurate way to look at the cuff, while MRI gives a fuller picture of tear size, tendon quality and muscle condition, which guides whether a repair is likely to succeed.
Common symptoms
- Pain over the top and outside of the shoulder
- Pain reaching overhead or behind the back
- Night pain, especially lying on the affected side
- Weakness lifting or rotating the arm
- Clicking or catching sensations
- In larger tears, difficulty raising the arm at all
How long will you wait?
A routine NHS shoulder referral typically means a wait of several months across clinic, scanning and surgery if needed, with around a third of patients on the national waiting list currently waiting more than 18 weeks.
Privately, you can typically see a shoulder specialist within 3–7 days, with scans arranged within days and surgery, if needed, usually within 2–6 weeks.
NHS England median referral-to-treatment wait: 12.4 weeks, with 2.5 million people waiting over 18 weeks (May 2026). Individual waits vary by trust and urgency.
Treatment options
- Physiotherapy. Progressive strengthening of the cuff and shoulder blade muscles is the mainstay for tendinopathy and many degenerative tears.
- Steroid injection. An image-guided injection can relieve pain enough to allow effective rehabilitation, though repeated injections are avoided.
- Arthroscopic rotator cuff repair. Keyhole surgery reattaches the torn tendon to the bone, most beneficial for acute tears and persistent symptomatic tears in active patients.
- Subacromial decompression. Removing bone spurs and inflamed tissue above the tendon can help selected patients whose symptoms persist despite rehabilitation.
What does private treatment cost?
As a guide, self-pay arthroscopic rotator cuff repair in the UK typically costs around £6,500–£9,000, depending on tear size and the implants used.
Does health insurance cover rotator cuff injury?
New rotator cuff injuries are normally covered by private medical insurance, including scans, injections, surgery and post-operative physiotherapy. Shoulder problems that existed before the policy started are usually excluded as pre-existing. Because cuff rehabilitation is lengthy, it is worth checking your policy's outpatient and physiotherapy limits before committing to surgery.
Frequently asked questions
Can a rotator cuff tear heal on its own?
A torn tendon does not reattach itself to bone, but that does not mean surgery is inevitable. Many people, particularly with degenerative tears, become pain-free and regain good function through strengthening the surrounding muscles. Acute tears after an injury in younger or active people are more likely to warrant early repair, as delay can make surgery less successful.
How long is recovery after rotator cuff repair?
Expect a sling for around four to six weeks while the tendon heals to bone, then graduated physiotherapy. Most people regain good everyday function by three to four months, with strength continuing to improve for six to twelve months. Returning to heavy lifting or overhead sport too early risks re-tearing the repair.
Is a steroid injection safe if I might need surgery later?
Generally yes, in moderation. A single well-placed injection can break the pain cycle and enable rehabilitation. Surgeons usually avoid repeated injections into the same shoulder, as steroids can weaken tendon tissue, and most prefer a gap of a few months between an injection and any repair surgery.
