Description of intervention(s) / exposure
Education and exercise:
The trial intervention will be delivered by a registered physiotherapist with experience delivering education and exercise interventions to patients with lower limb musculoskeletal conditions. The education and exercise intervention will be delivered in a group setting at a physiotherapy clinic with approximately four participants per group/class. There will be two education sessions which will discuss what osteoarthritis is; the diagnosis and symptoms of ankle osteoarthritis; recommendations from international guidelines for managing osteoarthritis; research evidence for the treatment of ankle osteoarthritis; Australian physical activity guidelines and tips; and information about the exercise and education intervention that participants will undertake. The education sessions will be guided by a PowerPoint presentation and accompanied by hard copy handouts, both of which have been designed for the intervention. The exercise program will include an aerobic exercise warm up (e.g., cycling on a stationary bike), and exercises to improve foot and ankle muscle strength (e.g., resisted ankle eversion and body weight resisted heel raises), compound lower limb strength and function (e.g., step ups and bridges), and balance (e.g., standing balance exercises). Exercise difficulty/load will be individually evaluated and progressed for each participant. Participants will attend the 2 education sessions and 12 exercise sessions twice weekly over 7 weeks. The 2 education sessions will occur in the first week of the intervention and the 12 exercise sessions will occur twice weekly for the next 6 weeks (e.g., weeks 2-7). Each session will be approximately 1 hour in length. Attendance and exercise completion will be recorded by the treating physiotherapist at each session. Participants will not be given home exercises during the 7-week program, but will be given a home exercise program after the final group exercise session. The home exercise program includes the exercises that participants performed in the group exercise program. Participants will be provided with a handout of the exercises and resistance bands. They will be asked to continue to perform the exercises twice a week (as they did during the group sessions).

General osteoarthritis advice:
The general osteoarthritis advice intervention will be provided by a registered physiotherapist and delivered at a physiotherapy clinic. Participants will attend one 1-hour group session where they will receive general information on osteoarthritis based on the online resources from Musculoskeletal Australia and Arthritis Australia’s Physical Activity Guidelines for individuals with Osteoarthritis. The session will be guided by a PowerPoint presentation and participants will be provided with the online resources identified above, and a small handout of tips for managing ankle osteoarthritis that has been designed for the intervention. From the Musculoskeletal Australia resource, general information about osteoarthritis and the role of exercise, weight management, medication and self-management in managing symptoms associated with osteoarthritis will be discussed. From Arthritis Australia’s Physical Activity Guidelines for individuals with Osteoarthritis, the session will include information about exercise recommendations.
In contrast, the education delivered to the exercise and education intervention group contains specific information on ankle osteoarthritis (e.g., anatomy, diagnosis, symptoms and evidence for management), recommendations from international guidelines for managing osteoarthritis (e.g., National Institute for Health and Care Excellence, American College of Rheumatology, and Royal Australian College of General Practitioners), Australian physical activity guidelines and tips, and information about the exercise and education intervention that participants will undertake.
There will be approximately four participants in per general osteoarthritis advice session. Attendance will be recorded by the physiotherapist delivering the session.

Summary
Brief summary
Ankle osteoarthritis is a debilitating condition that affects individuals of working age and is characterised by high levels of pain and disability. However, very little is known about how to manage ankle osteoarthritis. While education and exercise interventions have been shown to be successful in the management of hip and knee osteoarthritis, such an intervention has not been investigated in ankle osteoarthritis. The proposed study will establish the feasibility and credibility of a combined education and exercise intervention for ankle osteoarthritis. Secondary outcomes will explore whether education and exercise can improve pain, stiffness, function, and quality of life in this population. This study will determine the feasibility of conducting a full-scale randomised clinical trial investigating education and exercise in people with ankle osteoarthritis and inform the selection of outcome measures. It is an essential first step in determining the effectiveness of an education and exercise intervention for individuals with ankle osteoarthritis. Study findings have the capacity to change the way ankle osteoarthritis is managed and inform the development of clinical practice guidelines to help clinicians make evidence-based decisions when managing people with ankle osteoarthritis.
