Shoulder Surgery (Rotator Cuff)

The rotator cuff is formed from four muscles and tendons that attach your arm to the top of your shoulder blade (acromion). If the rotator cuff becomes weak or tears, you can get pain and weakness.

There are usually two types of damage that can happen to the rotator cuff:

• Rotator-cuff tear – This is often caused by a fall or lifting something heavy.
• Impingement – The area where the rotator cuff moves is protected by soft tissue called the bursa. The rotator cuff and the bursa can rub on, or get squeezed by, the collarbone or shoulder blade.

You should get less pain and be able to use your shoulder more easily but you are unlikely to get back the same strength that you had before you damaged your shoulder.

Most people with impingement or a small tear can get back good function in their shoulder by changing their activities, and with the help of exercises and physiotherapy.

Simple painkillers such as paracetamol and anti-inflammatory painkillers such as ibuprofen can also help.

A steroid and local-anaesthetic injection into your shoulder can sometimes reduce pain for several months but may cause side effects if repeated too often.

The operation is usually performed under a general anaesthetic but various anaesthetic techniques are possible.

The operation usually takes 45 minutes to an hour.

Keyhole surgery

Your surgeon will make three or four small cuts at the front and back of your shoulder and on the side of your upper arm.

They will insert surgical instruments through the cuts along with a telescope so they can see inside your shoulder and perform the operation.

Your surgeon will use the instruments to remove any thickened tissue, release any tight tissue and to shave off some bone so there is more room for your rotator cuff to move.

Open surgery

Your surgeon may use open surgery to repair any tears. They will make a single cut on the front of your shoulder. They will repair the rotator cuff using stitches that anchor into the bone.

You should be able to go home the same day.

It can take up to a year to get back enough strength in your shoulder to return to normal activities.

Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, ask the healthcare team or your GP for advice.

You may not get back the same strength that you had before you damaged your shoulder.

Some complications can be serious and can even cause death.
