Hip replacement is the removal and replacement of portions of the pelvis and femur (thighbone) that form your hip joint during a surgical procedure. A prosthetic implant replaces the hip joint, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi replacement.

Hip replacement replaces portions of the hip joint are with implants (prostheses). A surgeon removes the damaged sections of your hip joint during hip replacement and replaces them with parts usually constructed of metal, ceramic, and very hard plastic.

It is performed primarily to relieve pain, discomfort, and stiffness caused by hip arthritis. It can also treat broken or improperly growing hips. Hip replacement reduces pain and improves function.

Total hip replacement or "total hip arthroplasty" is the most common type of hip replacement surgery. Total hip replacement is a smart option for people with hip pain that interferes with daily activities, and alternative treatments have not worked, or their effectiveness has stalled over time.
