Hip replacement surgery is an operation to replace a damaged hip joint using an artificial ball and socket joint, known as a prosthesis. Hip replacement surgery helps to restore movement in the hip and increase patient mobility.
After your hip replacement surgery, you should be able to walk much better and carry out more of your normal activities.
The hip is a 'ball and socket' joint that is susceptible to wear and tear which can be caused by injury or various bone diseases including osteoarthritis. This can often lead to severe hip pain and lack of mobility affecting your daily life, which will worsen over time. If medication cannot help, then the best option may be a hip operation to replace the affected hip joint with an artificial one.

Hip replacement surgery is performed in hospital usually under general anaesthetic though regional anaesthetic can also be used. You would normally be admitted the evening before the operation and normal checks will be carried out. An injection to thin your blood will be given the same evening.
You will not be able to eat for eight hours prior to your hip surgery although you will be able to drink small amounts of water up to four hours before.
Before the operation, your consultant anaesthetist will visit you to discuss which anaesthetic technique is best for you and, once the anaesthetic is administered, you will be fitted with a urinary catheter which will need to remain in place for a couple of days.
Hip replacement surgery takes between 60 and 90 minutes. Your orthopaedic hip surgeon will make a small cut on the side of your hip to remove the damaged ball and socket, replacing it with an artificial hip joint which can be made of metal, plastic, ceramic or a combination of these materials.
Once the hip surgery is over you would normally stay in the theatre recovery area for six hours where specially trained recovery nurses will monitor you.

On average, patients are likely to stay in hospital for two to three days following this procedure. During this time we will get you mobile as soon as possible.
We will assist you to stand on the same day if the hip operation is carried out in the morning, if not then early on the next day. You will be able to go home once you are comfortable, walking confidently and are able to go up and down stairs with the help of a walking stick or crutch. Your physiotherapists will advise you on exercises in order to get you back to normal living and your nurses will provide you a discharge advice sheet.
You should see your own doctor's practice nurse about two weeks after your hip surgery who can contact your consultant if there are any concerns - our physiotherapists will see you a further two weeks later. You will have an outpatient appointment with your consultant after six weeks once an X-ray of your hip has been taken.

Hip replacement surgery is one of the most successful operations but there are some potential complications you should be aware of. These only affect less than 4% of patients.
- Infection can occur although we routinely prescribe antibiotics for the first 24 hours and our theatres have ultra-clean air operating conditions keeping infection rates at 1-2%.
- Blood clots are possible in any major joint replacement surgery but again are in the 1-4% category and have well-established treatments including aspirin.
- Dislocation of the joint and leg length inequality are possible but the risk is less than 1%. This is kept to the absolute minimum through your consultant using the recommended posterior approach to the hip joint and excellent discharge advice from your physiotherapists and nurses with a home visit if needed.
