Hip Revision Surgery

Hip replacement implants can last as long as 10 to 20 years. Patients who have a hip replacement may outlast the life of their implant, or the implant may wear out over time. A small percentage of people may need a new implant due to loosening or infection. During hip revision surgery, the old, damaged implant is removed and replaced with a new implant.

Indications for Hip Revision Surgery

There are several reasons that a patient might need hip revision surgery. Normal wear and tear on the hip implant can cause it to loosen. The friction of the implant components rubbing together can wear down the surface of the implant and create tiny particles that accumulate around the joint. The body attempts to digest these particles, in a process that wears away at the bond of the implant. This can cause pain and instability, as the hip joint no longer functions properly.

A very small percentage of patients may develop an infection in and around the original implant. Bacteria can latch onto the surface of the implant, which can cause an infection that could weaken or endanger the life of the patient. In this case, the implant may be removed and replaced with a new one.

Several factors can contribute to the wearing-down or loosening of a hip implant. Active and obese patients have an increased likelihood of wear or loosening. Patients who have had a previous hip fracture also have a higher risk of loosening.

If a patient experiences pain, swelling, stiffness, or instability in the hip, or the damaged, worn-out implant causes a significant limp or deformity, hip revision surgery may be considered.

The Procedure

During a hip revision procedure, the old hip implants are removed and replaced with new implants. The incision may be larger than the incision of the original procedure so that Dr. McLennan can more easily remove the old implant. The old cement is also removed, along with any abnormal bone or scar tissue that may be present. The bone is then prepared for the new implant. Patients who have severely damaged bone may require reconstruction of the bone using bone grafts or metal plates, cages, and screws.

If the patient has good-quality bone, the new implant may be made of a porous surface that allows the bone to grow into the implant, securing it into place. The new implant may also be cemented into place.


Rehabilitation is an important part of hip revision surgery. In most cases, physical therapy begins within 24 hours of the surgery and may continue for up to three months after the surgery. You may initially be restricted from bearing too much weight on the knee; you may also use assistance devices like a walker, crutches, or a cane in the early stages of recovery. As you heal, you will also need to pay attention to how you are sitting and bending, as well as to your sleeping positions. You may be restricted from doing certain activities for about six to 12 weeks.

Advances in surgical techniques and implant materials have allowed patients who undergo revision surgery to lead an active lifestyle for many years after the procedure.
