What is hip replacement?

If non-surgical treatments like physical therapy and medication don’t bring relief, your doctor may recommend hip replacement. Considered one of the most successful orthopaedic innovations of its time, hip replacements have been performed for more than 125 years.1 In fact, the procedure is performed more than 300,000 times every year in the U.S.2 The procedure involves removing the arthritic ends of bone and damaged cartilage and replacing them with prosthetic implants designed to move like a healthy hip.

What happens during surgery?

During total hip replacement (also called total hip arthroplasty), a surgeon removes the arthritic ball end of the femur (top of thigh bone) and inserts a metal component (a stem) into the bone. The surgeon also replaces the hip socket with an acetabular cup lined with durable polyethylene plastic.

Even with total hip replacement, you and your doctor have options. Talk to your doctor about robotic-assisted surgery and muscle-sparing approaches to hip replacement that are designed to minimize the impact of surgery on your soft tissue and bone.3-5

Joint replacement has serious risks.

Hip Replacements

Hip joint replacement is intended for use in individuals with joint disease resulting from degenerative and rheumatoid arthritis, avascular necrosis, fracture of the neck of the femur or functional deformity of the hip.

Joint replacement surgery is not appropriate for patients with certain types of infections, any mental or neuromuscular disorder which would create an unacceptable risk of prosthesis instability, prosthesis fixation failure or complications in postoperative care, compromised bone stock, skeletal immaturity, severe instability of the joint, or excessive body weight.

Like any surgery, joint replacement surgery has serious risks which include, but are not limited to, pain, infection, bone fracture, change in the treated leg length (hip), joint stiffness, hip joint fusion, amputation, peripheral neuropathies (nerve damage), circulatory compromise (including deep vein thrombosis (blood clots in the legs)), genitourinary disorders (including kidney failure), gastrointestinal disorders (including paralytic ileus (loss of intestinal digestive movement)), vascular disorders (including thrombus (blood clots), blood loss, or changes in blood pressure or heart rhythm), bronchopulmonary disorders (including emboli, stroke or pneumonia), heart attack, and death.

Implant related risks which may lead to a revision of the implant include dislocation, loosening, fracture, nerve damage, heterotopic bone formation (abnormal bone growth in tissue), wear of the implant, metal and/or foreign body sensitivity, soft tissue imbalance, osteolysis (localized progressive bone loss), audible sounds during motion, and reaction to particle debris. Hip implants may not provide the same feel or performance characteristics experienced with a normal healthy joint.

The information presented is for educational purposes only. Speak to your doctor to decide if joint replacement surgery is appropriate for you. Individual results vary and not all patients will return to the same activity level. The lifetime of any joint replacement is limited and depends on several factors like patient weight and activity level. Your doctor will counsel you about strategies to potentially prolong the lifetime of the device, including avoiding high-impact activities, such as running, as well as maintaining a healthy weight. It is important to closely follow your doctor’s instructions regarding post-surgery activity, treatment and follow-up care. Ask your doctor if a joint replacement is right for you.
