Total hip arthroplasty remains one of the most frequently performed reconstructive operations. Much work has again been done in this discipline over the past year with regard to scientific investigation, clinical outcome assessment, and the treatment of complications. In addition, controversies related to venous thromboembolism, medical-legal issues, and surgeon-industry relationships have been at the center of scrutiny and media coverage. We have elected to organize this update into six sections: (1) outcome of primary total hip arthroplasty, including bearing surface options; (2) outcome of revision total hip arthroplasty, including new methods of enhancement of bone growth and fixation; (3) hip resurfacing arthroplasty; (4) minimal incision surgery; (5) complications; and (6) practice management, including medical-legal issues, workforce issues, and industry-surgeon relationships.
