ABSTRACT
The International Society for Computer Assisted Orthopaedic Surgery (CAOS-International) is an organization, which aims at bringing together those individuals throughout the world, who, by their contributions and activities in the areas of biomechanical engineering, research, clinical study, and use, have indicated or are indicating interest in computer assisted orthopaedic surgery. CAOS-International has held annual meetings and related workshops and disseminated information to its members either at these meetings or independently, since its foundation in 2001. Its further purpose is to serve as a forum for the exchange of information of both an investigative and clinical nature, which relates to preoperative planning, intraoperative execution, and postoperative follow-up by means of computer assistance. The Society aims at promoting a new partnership between orthopaedic surgeons and technologists as a necessary basis for the successful integration of computer assisted surgical tools and techniques into the daily clinical routine. In China, this integration is at an early stage. Participation in CAOS-International' s activities to obtain the information helps China track the international current development and promote related research.
