Walter Moser graduated in mechanical engineering with a focus on material sciences after having studied at the Ruhr Universität Bochum, Germany, and the Technische Universität Munich, Germany. For 20 years he has dedicated his career to the development of orthopedic implants, instruments, and the associated surgical techniques. After graduation from the Technische Universität Munich, Germany, he spent four years doing research on crystallization of metallic alloys and its relevance to biomechanical application. In 1989, he received a PhD degree from the Technische Universität Munich, Germany, for his thesis on the relation of crystallization and mechanical properties of cobalt-base alloys. Since 1989 he has developed orthopedic implants and instruments for three international MedTech companies located in Switzerland. When the Total Knee Replacement Systems emerged in the 1990`s, he joined the PROTEK AG for 8 years and developed the company`s first modern Total Knee System. Later, he joined the Mathys AG Bettlach as head of product development and led the development of all joints for the upper and lower extremity for four years. Since the growing importance of computer-assisted surgery for orthopedics, he had dedicated his efforts to building up and leading the Department of Computer-Assisted Surgery at Plus Orthopedics in Aarau (PiGalileo System, today Smith & Nephew AG) between 2001 and 2009. This department was well-known for the development of navigated minimally invasive surgical techniques for total knee and hip joint replacements. Since 2009 he has been managing a start-up company with focus on innovative technical solution for Orthopedics (ATESOS medical AG).
