| Hip Anatomy |
| |
Your hip is one of the biggest weight-bearing
joints in your body. It is also commonly known as a ball-and-socket
joint and is made up of 2 parts:
 |
the ball or the head of your thighbone
(femur) and |
|
the hip socket (acetabulum) which
is the cup-shaped part of your pelvis. |
Your hip joint is surrounded by muscles, ligaments and tendons.
The membrane (synovial membrane) surrounding the hip produces small
amount of fluid to 'oil' your hip when you move. Cartilage covers
the surfaces of the ends of the bones. All these help you to move
your hip with comfort.
When the cartilage is damaged, it becomes rough or worn down from
arthritis. The hip bones will rub against each other during motion.
This will cause hip pain. |

| What is total hip replacement? |
| |
| In total hip replacement surgery, the painful damaged
parts of the hip are removed and replaced with a synthetic component
(prosthesis). The prostheses are made of metal with a layer of inner
plastic lining for the socket. These artificial parts are placed into
healthy parts of the pelvis and thighbone. Your surgeon may use a
special cement to secure these artificial parts. |

| What can I expect from my artificial hip? |
| |
| The surgery aims to relieve your pain and improve
function of the hip. Most people will have better hip motion and be
able to walk with comfort. You will be able to carry out many normal
activities of daily living. About 90% to 95% of total hip replacement
will last for 10 years. However, your new hip is not as good as a
normal hip. Therefore, you will need to stay away from certain activities
that will put your new hip to extra stress and load. |
