Commonly Asked Hip Replacemnt Surgery Questions Answered

Hip replacement surgery has been around for sometime and has become quite common these days. Here are some common questions about hip replacement surgery.

What does the surgery involve?

The joint where the upper side end of your femur (thigh) bone meets the socket (acetabulum) in the hip bone is known as the hip joint. It is just like a ball and socket joint and it allows a wide variety of motion that include standing, sitting, walking and other normal activities. During a hip replacement surgery the surgeon replaces the diseased cartilage and bone tissues of the hip joint with an artificial joint. A prosthetic ball with a stem replaces the original ball of your thigh bone and the worn socket is replaced by a prosthetic cup. Both form the artificial hip joint and also the smooth surfaces ensure comfortable movement.

How is the surgery performed?

On the day of the surgery, after inserting an intravenous tube into the patient's arm, for administration of fluids and medications during surgery, the patient is moved into the operation theater and administered anesthesia. Depending on the hip's condition the surgery lasts for 2 to 4 hours. It involves the common open surgery procedure. A urinary catheter is also usually inserted before the surgery.

Is any special preparation necessary for hip replacement surgery?

You will have to undergo a physical examination carried out your doctor before the surgery. All necessary tests like blood test, etc. are to be carried out in advance to eliminate any problems that may preclude a surgery. As you will need blood transfusion during the surgery it will help if you and your family members can donate blood in advance. You may also be advised to finish any pending dental work.

What happens after the surgery?

You will have to undergo a special rehabilitation program that will help you to regain your original range of motion and also for strengthening the muscles around the replaced hip joint. This will involve your physiotherapist who will help you to walk slowly a few steps each time after 24 hours and subsequently you will slowly use a walker and after that progress on to crutches and so on, until you are able to work normally again. Of course you will be under medical observation for some time after the surgery and will have to take medications for some days.

Are there any complications expected due to hip replacement surgery?

It is estimated by the American Academy of Orthopedic Surgeons that in the US every year about 120,000 cases hip replacement surgeries are carried out and less than 10% of these patients need any further surgery. Development of advanced surgical techniques has greatly reduced the risks associated with hip replacement surgery. However some patients do experience hip dislocation sometimes.
