Since Dr. W. Norman Scott and his co-founders formed the ICJR to establish a sense of professional community and to help educate the next generation of joint reconstruction surgeons, the ICJR meeting has been hosted by nations all over the world. This is the second ICJR meeting in Japan and we would like to provide an opportunity to exchange cutting-edge information focusing on total hip arthroplasty (THA). The ICJR Hip Japan consists of lectures and symposium by the distinguished international orthopedic surgeons. The topics include the present status of the metal on metal, past and future of the articulating surfaces and surgical approachs etc. We are confident that the attendees will obtain updated information on THA.
