Study Overview
Brief Summary
Education is an important part of knee osteoarthritis management. The aim of education is to help people with knee osteoarthritis make the best choices for them in terms of their treatment and lifestyle behaviours. Traditional education that describes the condition simplistically in terms of the joint damage and describes the cause of osteoarthritis solely with respect to loading through the joint can lead to activity avoidance and pessimism about the future progression of symptoms. An alternative is to provide the information about knee osteoarthritis management with the aim of giving hope for the future and building motivation and confidence to be physically active. This study will compare two educational videos that cover the same topics but with a contrasting 'discourse'. The experimental video has an 'empowerment and participatory' discourse, while the comparator or control video has a typical 'disease and impairment' discourse. The experimental video minimises mention of joint damage and instead corrects misconceptions about knee osteoarthritis, addresses common barriers to physical activity and incorporates behaviour change techniques such as social learning and modelling of desired behaviours. In this randomised controlled trial, people who report a history of knee problems consistent with knee osteoarthritis will complete questionnaires to determine their self-efficacy for managing knee osteoarthritis pain and their fear of movement. The participants will also be asked about their expectations for the future, their level of motivation to be physically active, and their knowledge about knee osteoarthritis. Participants will then be allocated one of the videos and asked to watch it before repeating the questionnaires.

- Double (Participant, Outcomes Assessor)
Masking Description
Limited disclosure will be used to blind participants and thereby reduce bias in responses since participants are also the assessors as all outcome measurements are self-reported. Participants will simply be informed that the trial aim is to assess knee OA educational videos. The investigators will not disclose details about how the educational content/presentation of the two videos differ, nor the hypotheses of the study. The biostatistician who performs the data analysis will be blinded.

Inclusion Criteria
- •live in Australia;
- •are aged 45 years or over;
- •have experienced activity-related knee pain during the past 3 months or have been told by a health professional that they have knee OA, ; and
- •are able to easily understand verbal and written English language.
Exclusion Criteria
- •have had a hip or knee joint replacement;

- •have any type of systemic arthritis (e.g. rheumatoid arthritis, gout), or have morning stiffness that lasts longer than 30 minutes;

Arms & Interventions
Experimental video
Knee OA educational video based on an empowerment discourse delivered online and embedded within the survey.
Intervention: Patient education (Other)
Control video
Knee OA educational video based on a disease and impairment discourse delivered online and embedded within the survey.
Intervention: Patient education (Other)
Outcomes
Primary Outcomes
Kinesiophobia
Time Frame: Immediately post intervention
Kinesiophobia is the fear that movement will exacerbate pain. According to the fear-avoidance model, fear is worsened by heightened negative emotion and hypervigilance to symptoms. Kinesiophobia will be measured with the Brief Fear of Movement Scale for Osteoarthritis (BFMS). Range 6-24, lower scores mean better outcome.
Self-efficacy for managing pain from osteoarthritis
Time Frame: Immediately post intervention
Self-efficacy is considered fundamental for effective chronic disease self-management and greater self-efficacy is related to higher physical activity levels in people with OA. Self-efficacy will be measured with the Arthritis Self-Efficacy Scale (ASES) (pain subscale). Range 0-10, higher scores mean better self-efficacy.
Secondary Outcomes
- Perceived change in feelings about having knee OA(Immediately post intervention)
- Expectations about their knee OA prognosis and benefit from physical activity(Immediately post intervention)
- Importance of physical activity(Immediately post intervention)
- Knee OA knowledge(Immediately post intervention)
- Motivation to be physically active(Immediately post intervention)
- Perceived personal likelihood of ever needing knee surgery(Immediately post intervention)
