Hip replacement replaces a damaged hip joint with an artificial ball and socket to relieve pain from arthritis or a hip fracture and restore movement.
Overview
In hip replacement, the worn or damaged ball (top of the thigh bone) and socket of the hip joint are replaced with artificial parts. It is a well-established operation for hip arthritis, avascular necrosis (loss of blood supply to the hip bone) and some hip fractures in older people.
The aim is to relieve pain, restore movement and help you walk without a limp.
Who needs this treatment?
- Persistent hip or groin pain that limits walking or sleep
- Stiffness that makes it hard to put on shoes or socks
- Arthritis or avascular necrosis seen on X-ray or MRI
- Certain fractures of the hip, especially in elderly patients
Benefits
- Significant pain relief for most patients
- Improved walking and independence
- Correction of limp and leg-length difference in many cases
- Early mobilisation, which lowers the risk of complications after a hip fracture
How it is done
Before the procedure
Pre-operative tests and a medical check-up are done to make sure you are fit for surgery. Medicines such as blood thinners may need to be adjusted.
During the procedure
Under spinal or general anaesthesia, the surgeon removes the damaged ball and socket and fits the new joint. The operation usually takes one to two hours.
After the procedure
You will be helped to stand and walk with support, usually within a day or two. Physiotherapy teaches you safe ways to sit, stand and climb stairs.
Recovery and aftercare
Most people walk with support for a few weeks and return to normal daily activities within two to three months.
- Follow the hip precautions taught by your physiotherapist to protect the new joint
- Use a raised toilet seat and firm chair if advised
- Continue exercises at home to strengthen the hip muscles
- Take blood-thinning medicines if prescribed to prevent clots
Frequently asked questions
Yes. Age alone is not a barrier. The decision depends on your overall health, and the team will assess your heart, lungs and other conditions before surgery.
A dislocation is when the new ball slips out of the socket. It is uncommon. Following the movement precautions you are taught, especially in the first weeks, reduces the risk.
