- Primary Outcome Measures
Name Time Method Difference in total Western Ontario and McMaster Universities Arthritis index (WOMAC) score total between D168 and inclusion visit. 168 days The Western Ontario and McMaster Universities Arthritis index (WOMAC) is a 24-item, condition-specific questionnaire available in a 5-point Likert and 100 mm visual analog scale (VAS) as well as an 11-box numerical rating scale, composed of three subscales: pain (5 questions), stiffness (2 questions) and physical function (17 questions). VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)

VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)
Pain at walking on a 100 mm VAS up to 168 days Percentage of subjects using analgesics up to 168 days New NSAID / analgesics drugs usage
Measurement of relief satisfaction by the patient 168 days 7-point Likert scale (1 point very unsatisfied to 7 points for very satisfied)
Measurement of therapeutic efficacy by the investigator (assessor) 168 days 7-point Likert scale (1 point very unsatisfied to 7 points for very satisfied)
Change in pain measurements, assessed using the Western Ontario and McMaster Universities Arthritis (WOMAC) pain severity index, as compared to D0 up to 168 days The Western Ontario and McMaster Universities Arthritis index (WOMAC) is a 24-item, condition-specific questionnaire available in a 5-point Likert and 100 mm visual analog scale (VAS) as well as an 11-box numerical rating scale, composed of three subscales: pain (5 questions), stiffness (2 questions) and physical function (17 questions). VAS was used in this study, with a score of 0 for no pain and 100 mm for the worst pain one can image)
Change in the Western Ontario and McMaster Universities Arthritis (WOMAC) functional severity index, as compared to D0 up to 168 days The Western Ontario and McMaster Universities Arthritis index (WOMAC) is a 24-item, condition-specific questionnaire available in a 5-point Likert and 100 mm visual analog scale (VAS) as well as an 11-box numerical rating scale, composed of three subscales: pain (5 questions), stiffness (2 questions) and physical function (17 questions).
