Arthroscopic release of frozen shoulder

Read Time:2 Minute, 25 Second

What is frozen shoulder?
Frozen shoulder is a stiff and painful shoulder caused by inflammation, swelling and contraction of your shoulder lining (capsule). It is also known as adhesive capsulitis.
What are the benefits of surgery?
You should have less pain and be able to use your shoulder better.
Are there any alternatives to surgery?
Simple painkillers and anti-inflammatory painkillers such as ibuprofen can help control the pain but you will usually need stronger painkillers. A steroid injection into your shoulder joint can sometimes reduce pain and stiffness. Physiotherapy is often helpful in improving movement if the pain can be controlled. Arthrographic hydrodilatation (stretching of the capsule by a high-pressure injection) has been shown to help.
It is possible to have a manipulation under anaesthesia (MUA) instead of a capsular release operation.
A frozen shoulder.
What does the operation involve?
Various anaesthetic techniques are possible.
The operation usually takes 30 minutes to an hour. Your surgeon will make two small cuts, about half a centimetre long, one at the front and one at the back of your shoulder. They will insert a small telescope through one of the cuts so they can examine the joint. They will insert surgical instruments through the other cut to divide the tight, thickened capsule to improve the range of movement of your shoulder.
How can I prepare myself for the operation?
If you smoke, stopping smoking now may reduce your risk of developing complications and will improve your long-term health.
Try to maintain a healthy weight. You have a higher risk of developing complications if you are overweight.
Regular exercise should help to prepare you for the operation, help you to recover and improve your long-term health. Before you start exercising, ask the healthcare team or your GP for advice.
If you have not had the coronavirus (COVID-19) vaccine, you may be at an increased risk of serious illness related to COVID-19 while you recover. Speak to your doctor or healthcare team if you would like to have the vaccine.
What complications can happen?
Some complications can be serious and can even cause death.

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.
