What is arthritis?

Arthritis is a group of conditions that cause damage to one or more joints.

The most common type of arthritis is osteoarthritis, where there is gradual wear and tear of a joint.

Some other types of arthritis are associated with inflammation of the joints that can eventually lead to severe joint damage.

Arthritis eventually wears away the normal cartilage covering the surface of the joint and the bone underneath becomes damaged. This causes pain and stiffness in the joint, which can interfere with normal activities.

What are the benefits of surgery?

You should get less pain and be able to walk more easily.

Are there any alternatives to surgery?

Simple painkillers such as paracetamol and anti-inflammatory painkillers such as ibuprofen can help control the pain of arthritis.

Using a walking stick on the opposite side to the affected knee can make walking easier. Wearing an elasticated support on your knee can help it feel stronger.

Regular moderate exercise can help to reduce stiffness in your knee. Physiotherapy may help to strengthen weak muscles.

A steroid injection into your knee joint can sometimes reduce pain and stiffness for several months.

What does the operation involve?

Various anaesthetic techniques are possible.

The operation usually takes an hour to 90 minutes.

Your surgeon will make a cut on the front of your knee and remove the damaged joint surfaces. They will replace these with an artificial knee joint made of metal, plastic or ceramic, or a combination of these materials.

The implant is fixed to the bone using acrylic cement or special coatings on your knee replacement that bond directly to the bone.

How soon will I recover?

You can go home when your pain is under control, you can get about safely, and any care you may need has been arranged.

You may need to use a walking aid for a few weeks.

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.

Most people make a good recovery, have less pain, and can move about better. An artificial knee never feels quite the same as a normal knee, and it is important to look after it in the long term.

A knee replacement can wear out with time.

Some complications can be serious and even cause death.

I can’t thank everyone enough for the amazing care given. Such lovely attentive nurses. I will definitely recommend St Hughs and Mr Riaz and his team. Brilliant hospital.

Could not fault anything about my stay in St Hughs. Everybody was wonderful. Thank you all.

Everybody was kind, considerate and a jolly bunch, which helps to put you at ease and gives you confidence in knowing that they know what they are doing. 5 stars.

All staff extremely kind, patient and friendly. A credit to the hospital. Thank you.

Very good hospital and very good staff. I have never met so many caring people in one place. The nursing was 1st class. The encouragement to walk was also very good.

I had an amazing experience during my time at St Hugh’s Hospital, from my initial consultation to the aftercare following my procedure. Communication with the cosmetic nurse was brilliant; every member of staff I met was kind respectful, caring and polite. My surgeon was fantastic, so professional and kind, I trusted his knowledge completely.
