Interventions
7.5mg x2 once a day for 12 weeks
Study subjects will be randomized to two treatment groups: one with Meloxicam 7.5 mgx2 once a day and another one with placebo. The duration of the interventional treatment is 12 weeks.

Change From Baseline in Short-Form 36 Health Survey (SF-36) Domain Scores and Component Scores at Week 12
The SF-36 is a self-administered questionnaire that measures each of the following 8 health domains: physical functioning, role limitations due to physical problems (role-physical), social functioning, bodily pain, mental health, role limitations due to emotional problems (role-emotional), vitality, and general health perception. There are also 2 component scores derived from the 8 subscale scores: physical component summary (including physical functioning, role-physical, bodily pain and general health) and mental component summary (including vitality, social functioning, role-emotional and mental health). Each SF-36 domain and component summary score ranges from 0 to 100, higher scores reflect better participant health status.
Time frame: Baseline and Week 12
Population: FAS: all randomized participants who received at least 1 dose of study medication using BOCF imputation method, number of participants analyzed=number of participants evaluable for the outcome measure, n=number of evaluable participants for each specific SF-36 domain.

Change From Baseline in WOMAC Subscale and Average Scores at Weeks 2, 4, 8 and 12
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. Change from baseline was calculated for each WOMAC subscale (pain, stiffness, physical function) and WOMAC average score.

Percentage of Participants With Cumulative Reduction From Baseline in WOMAC Pain Subscale at Week 12
WOMAC pain subscale is comprised of 5 questions regarding the amount of pain experienced in the index knee in the past 48 hours. The WOMAC pain subscale scores range from 0 to 10 with higher scores indicating higher pain. The WOMAC pain subscale score was calculated as the mean of the scores from the individual questions. WOMAC pain subscale response rates at Week 12 were shown for the reductions from Baseline of greater than (\>) 0%, 10% to 90% (in steps of 10%).
Time frame: Baseline and Week 12
Population: FAS: all randomized participants who received at least 1 dose of study medication using BOCF imputation method, number of participants analyzed=number of participants evaluable for the outcome measure.
