A hip replacement is a common type of surgery where a damaged hip joint is replaced with an artificial one (known as an implant).

Adults of any age can be considered for a hip replacement, although most are done on people between the ages of 60 and 80.

A modern artificial hip joint is designed to last for at least 15 years. Most people have a significant reduction in pain and improvement in their range of movement.

When a hip replacement is needed

Hip replacement surgery is usually necessary when the hip joint is worn or damaged so that your mobility is reduced and you are in pain even while resting.

The most common reason for hip replacement surgery is osteoarthritis. Other conditions that can cause hip joint damage include:

• rheumatoid arthritis
• hip fracture
• septic arthritis
• disorders that cause unusual bone growth (bone dysplasias)

Who is offered hip replacement surgery

A hip replacement is major surgery, so it is usually only recommended if other treatments, such as physiotherapy or steroid injections, have not helped reduce pain or improve mobility.

You may be offered hip replacement surgery if:

• you have severe pain, swelling and stiffness in your hip joint and your mobility is reduced
• your hip pain is so severe that it interferes with your quality of life and sleep
• everyday tasks, such as shopping or getting out of the bath, are difficult or impossible
• you're feeling depressed because of the pain and lack of mobility
• you cannot work or have a social life

You'll also need to be well enough to cope with both a major operation and the rehabilitation afterwards.
