Primary Outcome Measures

Name	Time	Method
Pain intensity measured as the average knee pain over the past week using a numerical rating scale of 0 to 10, where 0 is 'no pain' and 10 is 'the worst possible pain'.[Baseline and at 2, 6, 10, 14, 18, 22 and 26 weeks after randomisation.]

Secondary Outcome Measures

Name	Time	Method
Disability and function assessed using the Western Ontario and McMaster Universities Osteoarthritis Index.[Baseline and at 6 and 26 weeks after randomisation.];Patient quality of life assessed using the SF-12.v2.[Baseline and at 6 and 26 weeks after randomisation.];Diet assessed using a short food frequency questionnaire.[Baseline and at 6 and 26 weeks after randomisation.];Physical activity assessed using the Active Australia Survey.[Baseline and at 6 and 26 weeks after randomisation.];Weight (kg) assessed by a trained research assistant using a portable digital scale measured to the nearest 0.1kg.[26 weeks post-randomisation]
