About the show

Joint Action is a podcast hosted by David Hunter. As a consequence of isolation, those living with osteoarthritis related disability may become less fit, more depressed and anxious, more socially isolated and gain weight. It is critical at times like this that people with osteoarthritis have their burden and disability minimised and their knowledge of how to manage the disease enhanced. Join David as he interviews the world's leading experts in osteoarthritis. Professor David Hunter is a rheumatology clinician researcher whose main research focus has been clinical and translational research in osteoarthritis. He is the Florance and Cope Chair of Rheumatology and Professor of Medicine at University of Sydney and the Royal North Shore Hospital, Sydney, Australia.

Robotics in knee replacement with Prof Chris Vertullo

Nov 8, 2026 33 min

Robotic surgery promises precision. But does it translate into better outcomes for patients having knee replacement? In this episode of Joint Action, Professor David Hunter speaks with Professor Christopher Vertullo, an orthopaedic knee surgeon and researcher based on the Gold Coast. Chris is Clinical Director of the Australian Orthopaedic Association Clinical Trials and Data Analytics Unit, Director of Knee Research Australia, and a past President of the Australian Knee Society. His research uses large-scale registry data and randomised controlled trials to determine which surgical treatments actually make a difference for people with knee conditions. This conversation dives into the findings of two landmark trials, the RACER-Knee study and the RASKAL trial, which together put robotic-arm-assisted knee replacement to the test. What does the evidence actually show? And what should patients and clinicians make of it? Whether you are weighing up surgical options for knee osteoarthritis or simply want to understand where the science stands on one of the most hotly debated tools in modern orthopaedics, this episode is worth a listen.

The Consumer Voice with John Day

Oct 25, 2026 35 min

Patients are not just the subjects of research. They are essential partners in shaping it. In this episode of Joint Action, Professor David Hunter sits down with John Day, a consumer advocate who has spent years ensuring that the voices of people living with osteoarthritis are heard where it matters most: in research, education, and healthcare design. John's journey into advocacy began with his own experience of OA, and since retiring from a career spanning education and organisational leadership, he has channelled that energy into workshops, studies, and focus groups dedicated to keeping the patient perspective at the centre of the work. John’s career began in education, teaching mathematics and science before moving into educational planning. He later held leadership roles as Business Manager of a large secondary college and Assistant Director of Mary MacKillop Place during World Youth Day 2008. Since retiring, John has remained actively involved in his community through a range of volunteer roles. Drawing on his own experience of osteoarthritis, John has also become a consumer advocate by being involved in studies, workshops and focus groups, to ensure that the voices of people living with OA are represented in research and education. John also enjoys spending time with his five grandchildren, cultivating bonsai, and travelling with his wife, Margaret. Whether you are a researcher, clinician, or someone living with osteoarthritis, this conversation is a reminder of what becomes possible when people with lived experience have a seat at the table.

Do you really need surgery for your knee osteoarthritis? with Dr Howard Luks (2021)

May 10, 2026 41 min

The number of surgical procedures for musculoskeletal diseases such as osteoarthritis has increased exponentially over the past years, some of which are unnecessary and leave patients no better off than they were before. Knee replacement surgery can be a wonderful and cost-effective treatment for end-stage osteoarthritis but only when less invasive treatments have failed. There are many factors driving the alarming rates of increased surgery ranging from system-level factors such as inadequate reimbursement for physiotherapy treatment to personal-level factors such as individual beliefs and education of patients and their health care providers. Frequently referrals are made to surgeons as primary care doctors feel there is nothing more they can do. If you are referred it is important to be prepared for what that consultation will involve and to consider whether you truly want/ need surgery. On this episode of Joint Action, we are joined by Dr Howard Luks to discuss this topic. Dr. Howard Luks is a Board-Certified Orthopaedic Surgeon and Sports Medicine specialist. Howard graduated from New York Medical College and completed his Orthopaedic Surgery residency in 1996 and a fellowship in Sports Medicine at the Hospital for Joint Diseases in NYC in 1997. His focus is on injuries that involve the shoulder, knee, and elbow. He is the Chief of Sports Medicine and Arthroscopy at New York Medical College and Advanced Physician Services.

Reframing pain for osteoarthritis with A/Prof Tasha Stanton (2022)

Jan 4, 2026 37 min

On this week's episode we discuss reframing pain in the context of osteoarthritis. The purpose of today’s conversation is to help you reconceptualise what pain means and shift the dialogue from pain being solely a marker of tissue damage and discusses the nervous system adaptations that occur as pain persists. Further we discuss education programs that target this knowledge and the beliefs that may underlie behaviours that detract from your ability to be physically active and modify your behaviour. Associate Professor Tasha Stanton leads the Osteoarthritis Research Theme within IIMPACT in Health at the University of South Australia, Adelaide. Her research group is affiliated with the Body in Mind Research group in Adelaide (University of South Australia). Tasha completed her PhD at the University of Sydney in 2010 and is currently a National Health & Medical Research Council (NHMRC) Career Development Fellow (2019-2022). She has received over $5.3m in competitive research funding to date, including a highly renowned Canadian Institute of Health Research Postdoctoral Training Fellowship (2011-2014) and NHMRC Early Career Fellowship (2014-2018). Her research aims to understand why we have pain and why, sometimes, pain doesn't go away.

Can knee realignment slow down osteoarthritis? A discussion with Dr Trevor Birmingham and Dr David Parker

Sep 28, 2025 28 min

High tibial osteotomy (HTO) is a limb realignment surgery which is intended for people who have medial compartment osteoarthritis (OA), but are not suitable candidates for total knee replacement due to younger age, less severe disease and greater physical demands. The aim of HTO is to correct alignment, thereby shifting load away from the more involved knee compartment and limit progression of knee OA. On this week's episode of Joint Action, we are joined by Dr Trevor Birmingham and Dr David Parker to discuss high tibial osteotomy surgery, who it is suitable for and the risks involved. Professor Trevor Birmingham is a physiotherapist and Canada Research Chair in Musculoskeletal Rehabilitation at the University of Western Ontario in London, Canada. He leads research on musculoskeletal health, often combining clinical outcomes with biomechanical, imaging and biological measures in cohort studies and randomized trials. He co-directs the Wolf Orthopaedic Biomechanics Lab at the Fowler Kennedy Sport Medicine Clinic and is a founding member of the Bone and Joint Institute and the Collaborative Graduate Training Program in Musculoskeletal Health Research at Western University.

In Memoriam: Prof Frank Beier - new insights into osteoarthritis onset (2021)

Sep 14, 2025 29 min

This week's episode is in honour of Frank Beier, who recently passed away on July 18, 2025. Frank leaves behind a remarkable legacy through the impact he made in the field of osteoarthritis. In this previous episode (2021), he discussed the recent advances in osteoarthritis understanding with a particular emphasis on novel targets and epigenetics. Despite the large prevalence of osteoarthritis, there is no clinically approved drug which provides a cure. Currently, drugs focus on relieving symptoms such as pain. Experiments done in the laboratory have provided insight on osteoarthritis onset and progression and will likely guide therapeutic development. We know that osteoarthritis is a disease of the whole organ meaning that any of the tissues involved in the synovial joint can be affected. The interplay between the various cell types involved is complex and understanding the interactions between cartilage, bone and synovium may be critical to therapeutic development. Skeletal development likely plays a very important role in predisposition to disease. Through the identification of serious pathologies such as various forms of dwarfism (what in medical terms are called chondrodysplasias) the role of transcription factors and epigenetics is increasing our understanding of disease genesis.The study of the epigenetics of OA - the mechanism by which the human genome alters it’s gene expression (without changing the primary DNA sequence) has provided valuable information on novel risk factors for the disease and are potential therapeutic targets for OA.

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.

Hormones, menopause, and joint pain with Dr Ginni Mansberg

Feb 16, 2025 39 min

Menopause is often referred to as "the change" and remains a complex and sensitive topic for many. Despite being historically under-discussed, it's crucial to address because of its profound impact on musculoskeletal health. Women are two to three times more likely than men to develop osteoarthritis, particularly around menopause. Changes in hormones, such as declining estrogen, can affect cartilage, bone density, inflammation, muscle health, and body weight - factors closely linked to joint pain and osteoarthritis symptoms. In this episode of the Joint Action Podcast, Dr. Ginny Mansberg, a GP and women's health expert, joins Prof. David Hunter to explore the intricate relationship between menopause and osteoarthritis. They discuss the physical and emotional challenges women face, including sleep disruption, weight gain, joint pain, and mental health issues like anxiety and depression. Dr. Mansberg shares valuable insights into how hormone replacement therapy (HRT) and lifestyle strategies, including exercise, can help manage symptoms and improve long-term health outcomes. Whether you're navigating menopause or supporting someone who is, this episode offers a compassionate, evidence-informed perspective on understanding and managing the journey.
