A hip replacement involves a surgical procedure to replace part or all of a diseased or damaged hip joint with an artificial substitute-a prosthetic hip joint. The operation to replace or mend a joint is known as ‘arthroplasty’. The aim of a hip replacement is to alleviate pain and restore function in the hip joint.

A hip replacement may become necessary to prevent pain and increase mobility if your hip joint is damaged as a result of disease or injury. The most common cause of hip replacements is osteoarthritis, but the procedure may also be necessary for people with rheumatoid arthritis, osteonecrosis, bone tumours or a fracture or dislocation affecting the hip joint.

You may feel some numbness in the skin around your incision. You also may feel some stiffness, particularly with excessive bending. These differences often diminish with time and most patients find these are minor compared to the pain and limited function they experienced prior to surgery.

Your new hip may activate metal detectors required for security in airports and some buildings. Tell the security agent about your hip replacement if the alarm is activated.
