Objective To describe the level and perception of the physical activity for patients with knee osteoarthritis in 9 spa resorts Method Five hundred and forty-eight patients (548) with knee osteoarthritis were interviewed by self-answered questionnaires. Physical activity level was evaluated by the International Physical Activity Questionnaire Short version (IPAQ)  and perception of physical activity by a new questionnaire (EPAP) based on a preliminary qualitative study. Results The mean age of study population is 67.6 (+/- 7.9) years, whose 73.9% women and 30.9% are obese with a mean BMI of 28.2 (+/- 5.7). The subgroups analysis according to the 4 phenotypes described by the OARSI  shows that 92% patients are multi-joint osteoarthritis, 61% with comorbidities. Mean pain intensity on VAS is 4.5/10 and 67% of patients uses analgesics at least once a week. Only a third of patients receive a non-pharmacological treatment according to the latest guidelines . According to the IPAQ, 42.6% of patients have a high level of activity, 38.6% moderate and 18.8% low. Obese patients have a significantly lower level of physical activity (p < 0.05). The facilitators are mainly biopsychosocial, cultural and environmental, while the barriers are mainly biomedical. Discussion Osteoarthritis spa resort patients are more active than the general population, despite a high level of pain. The literature shows that patient multidisciplinary care for knee osteoarthritis including self-care and exercise improves pain,physical function and contributes to weight reduction. This study can help adaptation of osteoarthritis management, taking into account the patient's history, his psychology and his phenotype. This strategy could permit to offer tailored educational strategies regarding physical activity.
