Ceramic-Ceramic Bearing in Difficult Hips (Primary and Revision)

摘要

The primary goal of total hip arthroplasty (THA) is to provide the patient with end-stage arthritis of the hip with a long-lasting, pain-free, functional hip joint. The average age of a primary THA patient is decreasing, and younger, more active patients require hip implants that will last for decades (Manley and Sutton 2008). Furthermore, patients with severe osteoarthritis secondary to developmental dys-plasia of the hip (DDH), initial diagnosis of avascular necrosis of femoral head, posttraumatic arthritis, and rheumatoid arthritis are known to adversely influence the long-term outcome of THA.
