You do not have to live with a painful hip for the rest of your life. During this surgery your problem hip joint is replaced with an artificial joint (a prosthesis). After a total hip replacement, you can look forward to moving more easily and without pain.
Total hip replacement is a “quality of life” elective operation, offered to patients when their pain and disability are significant as a procedure that will decrease their discomfort.
The aim of the operation is to replace the head of the femur (ball) and the acetabulum (socket) with a man made device (prosthesis). The femoral component goes into the femoral canal and has a ball attached to the top. The acetabular component goes in to the socket in the pelvis and a liner is inserted into this. These devices are combinations of metal and plastic or ceramic on ceramic. They are fixed to the bone either using bone cement or by using a prosthesis with a rough surface, which relies on your bone growing on to the implant for long term stability.
Most people gain all the following benefits:
Patients who have arthritis on their X-ray and pain and stiffness from their hip joint that causes:
This operation is one of the most cost effective and beneficial operations done in surgery. Hip replacement surgery has evolved significantly over the last 40 years since first performed. There are improvements constantly being made but modern day hip replacements are extremely sophisticated and function well for many years.
However, there are risks in any operation. You can read about the general complications here. Some complications specific to total hip replacement are:
You will be required to attend a pre admission clinic. Everything you need to know about what to do before, during and after your stay in hospital will be discussed at length at this clinic. Your doctor will also examine you and ask you questions, and you should let them know if you have any abrasions or pimples around the hip.
At this clinic the following will be attended to:
You will have simple blood tests to make sure your blood count is normal and you have no other major medical problems. Because hip replacement is such a major operation with drilling and cutting involved there is a higher risks than in most operations of the health care team catching diseases transmitted by blood. For this reason, a sample of your blood will also be tested for AIDS and hepatitis. The results of this test can take up to two weeks.
A cardiograph of your heart will be taken to make sure you have no underlying cardiac problems. An ECG is non-invasive - no needles, just some stickers on your body that communicate to a machine through wires.
Your doctor may or may not require new X-rays of the hip he is operating on.
This is required to make sure you do not have a urinary tract infection. An infection anywhere before surgery e.g. infected toenail, skin lesion, throat infection, gum or dental infection, can greatly increase your chances of infection of the joint replacement following surgery. If an infection is found, it can be treated with simple antibiotics prior to surgery.
People usually can return to work somewhere from eight to twelve weeks. Heavy manual work may take longer.
When you feel comfortable and when you have regained muscle control. For most people, this is usually by six weeks. Please also check with your insurance company as they may have specific rules on when you can drive after surgery.
Sexual intercourse is allowed when the patient is comfortable but they have to be in charge of the positions used and any significant discomfort should result in the patient abstaining until they talk to their doctor.
In general, sexual intercourse occurs at around three to six weeks post operatively.
Normally by three months you can play sports like golf, bowls, stationary bike ride, bush walk, doubles tennis and swim. Jogging and heavy weights, although possible, will wear the joint prematurely. Contact sports are not appropriate.
Remember this is an artificial hip and must be treated with care.
In general, the more active you are, the quicker your hip will wear out.
Avoid situations where you might fall.
