Brief summary

This study aims to assess the effectiveness of providing information about osteoarthritis and its management to people with knee osteoarthritis. Information about osteoarthritis and its management may help people make more informed decisions about the care they receive and the decision on whether or not to undergo surgery. Participants in this study will be randomly allocated to one of two study groups, each receiving a different intervention.

Interventions

Brief name: Patient decision tool All patients allocated to the intervention group will be emailed a written patient decision tool after completing the eligibility screening and consent form. At the same time, they will also receive information readily available electronically – an Arthritis Australia information sheet about osteoarthritis. This provides general information about the condition and how to manage it but no information about surgical options. The decision tool is designed to help

Brief name: Patient decision tool All patients allocated to the intervention group will be emailed a written patient decision tool after completing the eligibility screening and consent form. At the same time, they will also receive information readily available electronically – an Arthritis Australia information sheet about osteoarthritis. This provides general information about the condition and how to manage it but no information about surgical options. The decision tool is designed to help people with knee osteoarthritis decide whether or not they should have arthroscopic surgery. The decision tool provides a general introduction, an explicit statement of the decision to be taken (‘should I have arthroscopic surgery?’), and describes the likely benefits and harms of arthroscopic surgery compared with not having surgery. Estimates are provided using pictographs and described in words with the source of estimates explicitly stated. Key practical issues associated with each option is provided, as well as information on other treatment options. Patients will be allocated to the intervention group or the control group. The intervention will not be personalised. Adherence will not be assessed.
