Implant Wear: The Future of Total Joint Replacement is a new addition to the Academy's Symposium Series. It is based on a workshop conducted by the Academy, and supported by the National Institutes of Arthritis and Musculoskeletal and Skin Diseases. The new book details in a question and answer format the problem of wear in joint replacements; clinical and biologic consequences; and related biomechanical and biomaterial issues. It also identifies directions for future research and patient care. The book is a product of a collaborative discussion among clinicians, biologists, and bioengineers. It costs $28 for Academy members, and $35 for nonmembers. A flyer with this mailing of the AAOS Report contains an order form, or contact the Academy's customer service department, (800) 626-6726.
