Risk factors
Factors that lower a patient's chances for a good outcome from hip revision surgery include the following:
- Sex. Men are more likely to have poor outcomes from revision surgery than women, other factors being equal.
- Age....
Older patients, particularly those over 75, are more likely to have complications following revision surgery. - Race. African Americans have a higher rate of complications than Caucasian or Asian Americans.
- Socioeconomic status (SES). Patients with lower incomes do not do as well as patients in higher income brackets.
- Presence of other chronic diseases or disorders.
- Obesity. Many surgeons will not perform hip revision surgery on patients weighing 300 pounds or more.
- Genetic factors. Recent British research indicates that patients who carry an inflammation control gene known as TNF-238A are twice as likely to require replacement of a hip prosthesis as those who lack this gene.
Specific risks of hip revision surgery
Risks following hip revision surgery are similar to those following hip replacement surgery, including deep venous thrombosis and infection. The length of the patient's leg, however, is more likely to be affected following revision surgery. Dislocation is considerably more common because the tissues surrounding the bone are weaker as well as the bone itself usually being more fragile. One group of researchers found that the long-term rate of dislocation following revision surgery may be as high as 7.4%.

Degeneration of the joint around the prosthesis causes pain for some patients who have undergone hip replacement (A). To repair it, an incision is made in the hip and the old prosthesis is removed (B). Bone grafts may be planted in the hip, and a new prosthesis is attached (C). (Illustration by GGS Inc.)

Other Information
Hip revision surgery, which is 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 may also involve the use of bone grafts. The bone graft may be an autograft, which means that the bone is taken from another site in the patient's own body; or an allograft, which means that the bone tissue comes from another donor.

New procedures like minimally invasive procedures are often subject to scrutiny, but I think that one of the biggest problems facing these innovative procedures is for people to understand exactly what we do.
