Hip replacement

Various conditions can lead to hip replacement

The hip, one of the body's largest joints, is a ball-and-socket joint. The femoral head of the thighbone, or femur, is the ball portion, fitting into a socket portion of the pelvis.

The most common cause of chronic hip pain is various forms of arthritis including:

  • osteoarthritis that results from age-related wear-and-tear, 
  • rheumatoid arthritis in which the cushioning, or synovial, membrane in the joint becomes inflamed and thickened, or 
  • post-injury arthritis that sets in after an injury or fracture.

Some hip diseases or other injuries can cause hip pain, as well.

In hip replacement surgery, your surgeon will:

  • Remove the ball of your hip joint.
  • Shape your hip socket and remove the remaining damaged cartilage and arthritic bone.
  • Put the new hip cup and liner in place, then insert a metal stem and either a ceramic or a metal ball into your thigh bone.
  • Secure all the new parts in place.
  • Repair the muscles and tendons around the new joint.
