In this week's episode of Joint Action, Professor David Hunter is joined by Dr Sarah Kobayashi, a lecturer in anatomy and osteoarthritis researcher, to talk about the power of walking - especially for people with osteoarthritis.

Sarah shares her insights into the many health benefits of walking, why it’s so important for joint health, and how to overcome common barriers to getting started. She also introduces the CASCADE-OA study (Community bAsed phySical aCtivity AnD sElf-management for OsteoArthritis), a 12-month clinical trial exploring the effectiveness of a self-directed walking program, Walk With Ease Australia, in improving physical activity levels and managing symptoms for those with hip or knee osteoarthritis.

Whether you're new to walking or looking to establish a sustainable routine, this episode offers practical advice and motivation to help you take that first step.

Running often gets a bad rap when it comes to knee osteoarthritis - but is the fear justified? In this week's episode of Joint Action, Professor David Hunter speaks with physiotherapist and researcher Dr Jean-François Esculier to unpack common myths about running and joint health. They explore the latest evidence, share tips for safe running with OA, and discuss how to build joint resilience over time.

Tune in to learn why running might not just be safe - it could even be helpful.

High heels have long been associated with fashion - but what impact do they have on your joints? This week, Professor David Hunter is joined by physiotherapist and footwear researcher Dr. Kathryn Mills to unpack the biomechanics of high heels and their effect on knee health.

From changes in posture and joint compression to the importance of shoe comfort and replacement, this episode blends science with practical advice for anyone managing knee pain or osteoarthritis. Plus, learn what to look for in a good shoe and when to seek professional help from a podiatrist or physiotherapist.

Can joint replacements reduce pain, help you move more - and live longer? In this week's podcast episode, we explore the untold benefits of hip and knee replacements beyond pain relief. Dr Tim Lindsay, clinician and researcher at Imperial College London, joins us to share insights from large-scale studies that show how joint replacement can restore physical activity levels and potentially reduce premature mortality. We also discuss why recovery takes time, how expectations should be managed, and what patients can realistically achieve after surgery. If you're considering joint replacement or supporting someone who is, this conversation offers evidence-based clarity and hope.

In this episode of Joint Action, Professor David Hunter is joined by Dr. Bruno da Costa, Associate Professor of Clinical Epidemiology at the University of Toronto and Senior Scientist at the University of Oxford, to unpack the evidence behind injections for osteoarthritis.

Dr. da Costa shares insights from his recent systematic review and network meta-analysis of clinical trials, revealing just how limited - and at times unreliable - the evidence is for many joint injection therapies.

This episode explores:

• Which injections (if any) offer real benefit - and for how long
• The surprising extent of bias in osteoarthritis trials
• Why some results may not be as credible as they seem
• The role of placebo effects and commercial influence
• What this means for people living with osteoarthritis

If you’ve ever considered injection therapy, this episode will help you sort fact from fiction.

For too long, people living with osteoarthritis have felt powerless - like there’s nothing they can do to influence change. But that couldn’t be further from the truth.

In this powerful episode, Prof. David Hunter is joined by Louise Hardy, Director of Policy and Advocacy at Arthritis Australia, to explore how individuals can use their voice to drive meaningful change - especially in the lead-up to the Australian federal election.

Louise shares practical ways you can support better care, fairer funding, and more accessible services for the 7 million Australians living with arthritis. They discuss the importance of community-led advocacy, out-of-pocket costs, gaps in clinical care, and how you can be part of the solution, today.

Whether you live in Australia or abroad, this episode offers a roadmap for how your voice can make a difference - starting now.

MRIs are increasingly used to detect early signs of osteoarthritis - but are they truly beneficial for most people? On this week's episode, we examine the role of MRI scans in diagnosing knee osteoarthritis, particularly in its early stages. Joined by leading experts Dr. Alison Chang, a professor of Physical Therapy at Northwestern University, and Dr. Ali Guermazi, a Radiology professor at Boston University, we explore the genuine value of MRIs. Our discussion highlights when these imaging tests can be helpful and when they might lead to unnecessary interventions. We also discuss why many MRI-detected changes don't actually progress into osteoarthritis and share practical advice for effectively managing knee health.

Tune in for an evidence-based conversation to understand when MRIs truly add value - and when they may not.

What if you could know your risk of developing osteoarthritis years before symptoms appear? In this episode, we explore whether a blood test could provide those answers.

Joining us on this week's episode is Dr. Virginia Kraus, a leading rheumatologist and researcher, to discuss her study that identified osteoarthritis risk up to 10 years in advance with 77% accuracy. We unpack what this means for early detection, the role of inflammation in disease progression, and how this research could shape future treatment and prevention strategies.

Tune in to find out what the future of osteoarthritis detection could look like.
