Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame: Screening 1 (Visit 1: Days -21 to -14)
The WOMAC has 3 subscales: WOMAC pain subscale, WOMAC stiffness subscale and WOMAC physical function subscale, which are comprised of 5, 2 and 17 questions regarding the amount of pain and stiffness experienced in the index knee, and degree of difficulty in doing daily tasks, respectively in the past 48 hours. The WOMAC subscale scores range from 0 to 10 with higher scores indicating higher pain, more stiffness and worse function respectively for pain, stiffness and physical function subscales. The WOMAC subscale scores were calculated as the mean of the scores from the individual questions. The WOMAC total score was the sum of scores from the 5, 2 and 17 questions respectively on pain, stiffness and physical function subscales. WOMAC total score ranged from 0 to 240, where higher scores indicated worse health condition.
