The main aim of NetwOArk is to set up the European Society for Osteoarthritis (ESOA), with three major stakeholder groups, 1) patients, 2) clinicians and 3) researchers, both from academia and industry. The COST Action will allow us to start the process of building such a European Society, with the aim of coordinating and stimulating more interdisciplinary and transdisciplinary research, technological development and translation of the results to the clinic, aimed at improving the quality of life of those affected by osteoarthritis in Europe. The areas to be addressed in this Action are Primary prevention, Diagnostics, Treatment, Interaction (comorbidities) and Care Management. EU-netwOArk aims to boost new scientific breakthroughs on the five main osteoarthritis themes.
