Hip replacement surgery, also known as hip arthroplasty, is a surgical procedure that involves removing damaged bone and cartilage within the hip joint and replacing it with prosthetic components. It is one of the most common and successful operations for orthopedic concerns. According to the Agency for Healthcare Research and Quality, more than 450,000 total hip replacements are performed in the United States each year.
While hip replacement surgery can provide patients with relief and offers outstanding results, Southlake Orthopaedics does not rush to perform surgery as a first course of treatment. Only after non-invasive approaches have failed do we recommend hip replacement.
To ensure a patient is a good fit for hip replacement, our physicians perform the necessary testing, which can include X-rays, computed tomography (CT) scans, magnetic resonance imaging (MRI), and electrodiagnostics. These tests are administered to provide our orthopedic specialists with the full scope of a patient’s condition.
The procedure is performed while the patient is under anesthesia. After making an incision, the surgeon removes the damaged femoral head and replaces it with a metal stem that is placed into the hollow center of the femur. A metal ball is then placed on the upper part of the stem. From there, the damaged cartilage surface of the socket (acetabulum) is removed and replaced with a metal socket, using screws to hold the socket in place. Finally, a plastic spacer is inserted where the new ball and the socket meet to allow for a smooth gliding motion that mimics natural hip mobility.
