Rotator cuff and shoulder pain: what helps, and do you need surgery?

Rotator cuff pain is one of the most common reasons people come to physiotherapy. The good news is that for most people it responds well to a structured strengthening programme, and even when a tear is present on a scan, surgery is rarely the first, or best, answer. High-quality trials have shown that well-guided physiotherapy produces similar long-term outcomes to surgery for the majority of non-traumatic cases. That is why guidelines now recommend rehab as the first line of treatment for almost all non-acute shoulder pain.

What is the rotator cuff, and what goes wrong?

The rotator cuff is a group of four small muscles and their tendons that wrap around the shoulder, keep the head of the upper arm centred in the socket, and control almost every movement you make with your arm. Pain from the rotator cuff typically sits at the outside or front of the shoulder, spreads down the arm, and is worst reaching overhead, behind your back or lying on the affected side.

Most rotator cuff problems are not sudden tears. They are overload problems in the tendons, often with weakness and loss of control that has built up over time. Small degenerative tears are common with age and are frequently painless.

How is it diagnosed?

A physiotherapist will take a careful history, test the rotator cuff and surrounding shoulder muscles, check movement and control, and rule out the other things that can cause shoulder pain, including frozen shoulder, arthritis of the AC joint, and referred pain from the neck. Imaging is not routine. Scans often show changes in shoulders that are pain-free, so an MRI or ultrasound is most useful when a specific decision depends on it.

Do you need surgery?

In most non-traumatic cases, no. The Finnish trial by Kukkonen and colleagues showed no meaningful difference between surgery and physiotherapy for atraumatic supraspinatus tears at two years. The UK CSAW trial found that subacromial decompression surgery was no better than a placebo procedure. The current consensus, which our team follows, is that a fair trial of well-guided physiotherapy should come first for almost all non-acute shoulder pain. Surgery is considered for large, symptomatic, full-thickness tears in younger, active people, or when a well-run rehab programme has not moved things forward.

How is it treated?

The most effective treatment is progressive strengthening of the rotator cuff and the whole shoulder complex, including the scapular stabilisers and the surrounding trunk. Programmes typically start with isometric holds and low-range strength work if the shoulder is very irritable, then progress through resisted rotation, pulling and pressing work over 8 to 12 weeks. Around that, we address the neck if it is contributing, restore full range where that has been lost, and rebuild sport, gym or work-specific tasks. A steroid injection is considered when pain is preventing rehab.

What does recovery look like?

Most people notice a real change within 8 to 12 weeks of guided strengthening, and a return to sport, gym work or manual jobs within 3 to 6 months. Recovery is rarely linear. Flare-ups during the process are usually a sign to adjust load, not to stop.

When should you see a physiotherapist?

Shoulder pain that has been present for more than a couple of weeks, or that is waking you at night or limiting normal activity, deserves a proper assessment. Our physiotherapy team in Milton Keynes will diagnose what is going on, build the right programme for the stage you are at, and know when a surgical opinion is genuinely warranted. If your shoulder is stiff and losing range as well as painful, see our companion piece on frozen shoulder.
