Opis

Comprising presentations originally offered at the 2011 EFORT Congress, this book provides detailed information on articulating materials currently used in hip arthroplasty. Discusses wear performance and clinical outcomes and explores important new frontiers.

O autorze

Karl Knahr completed his medical studies at the University of Vienna in 1971 and subsequently trained as an orthopaedic surgeon at the Orthopaedic University Clinic of Vienna. In 1988 he became Head of the 2nd Orthopaedic Department at the Orthopaedic Hospital, Vienna-Speising and in the following year he was appointed Professor of Orthopaedic Surgery at the University of Vienna. For more than a decade, Professor Knahr has been the Austrian National Delegate to SICOT (Société Internationale de Chirurgie Orthopédique et de Traumatologie), President and current Treasurer of the Austrian Society for Orthopaedic Surgery, and Austrian National Delegate to EFORT. Since 2005 he has been a member of the EFORT Executive Committee. He is currently a member of the editorial boards of International Orthopaedics and the Archives of Orthopaedic and Trauma Surgery and previously served as an editorial board member for the Journal of Arthroplasty. Professor Knahr has published widely on the subjects of tribology and hip arthroplasty.

During the 2011 EFORT Congress in Copenhagen, many interesting topics relating to tribology in total hip arthroplasty were discussed during a special day devoted entirely to the subject. EFORT decided that, given the wide interest in these discussions, publication of the presentations would be warmly welcomed by all fellow professionals who were unable to attend. This book is the result. It provides detailed information on currently used articulating materials and their wear performance. Clinical outcomes are discussed, and important new frontiers are carefully considered. The book will be of interest both to novices who want to learn more about the field and to experienced orthopaedic surgeons wishing to keep abreast of the latest developments.
