It's been about a year since we last met with Mrs. Céline Mathy, Clinical Psychologist and Managing Director of the Osteoarthritis Foundation. You may recall or want to revisit her previous appearance on Let's Talk OA podcast series on the psychological impact of OA from 2021. Today, however, she is joining us to introduce the results from the Stop Arthrose 2019-2021 patient study. This study, conducted in Belgium and France, shows the evolution of OA, from patient's perspectives. This, in contrast with the previous wave and Mrs. Mathy's clinical experience as a psychologist may be able to lead us into a better understanding so as to why significant advances in OA seem to be... stuck.
