Hip osteoarthritis is a highly prevalent health condition among adults worldwide, and hip replacement surgery is the most common intervention for treating disabling end state hip osteoarthritis. In this book, the authors present current research in the study of the procedures, potential complications and postoperative rehabilitation in hip replacement surgery. Topics discussed include the nature and prevalence of hip replacement surgery among aging adults and the impact of prognostic factors such as age, gender, and body weight; the wear factor in total hip replacement bearing surfaces; hip replacement rehabilitation; forecast factors and management alternatives in hip fracture; and fretting wear at the stem-cement interface in total hip replacement.
