Hip Revision surgery, also known as Revision Total Hip Arthroplasty, is a procedure in which the surgeon removes a previously implanted artificial hip joint, or prosthesis, and replaces it with a new prosthesis.

Hip revision surgery has three major purposes: relieving pain in the affected hip, restoring the patient's mobility, and removing a loose or damaged prosthesis before irreversible harm is done to the joint.

Other less common reasons for hip revision surgery include fracture of the hip, the presence of infection, or dislocation of the prosthesis. In these cases the prosthesis must be removed in order to prevent long-term damage to the hip itself. Hip revision surgery may also involve the use of bone grafts.
