Brief Summary

The aim of this study is to evaluate the effect of educational information, with and without a general practitioner recommendation to exercise, on willingness to undertake exercise/physical activity for knee osteoarthritis. Eligible participants will be aged 45+ years and will not currently have osteoarthritis, knee pain, or any condition that makes them unable to exercise. Participants will be asked to complete an online survey, during which they will be randomised to one of three groups and shown different types of educational information to read. Outcome measures will be collected as part of the survey before and after participants read the educational information presented to them.
