Joint Action

Can two wheels really help ease joint pain? On this week's episode we are joined by Professor Tom Wainwright to discuss the benefits of cycling for hip osteoarthritis. He also discusses the findings of his recently completed randomised controlled trial comparing a cycling and educational intervention to usual physiotherapy care. Professor Tom Wainwright is a physiotherapist specialising in orthopaedic physiotherapy, researcher and educator. He has authored over 150 peer-reviewed publications is recognised as an international expert in Enhanced Recovery After Surgery (ERAS) protocols in Orthopaedics and was the lead author of the first ERAS Society guidelines for hip and knee replacement. Tom is passionate about improving the quality of healthcare systems and works to help other healthcare providers improve the quality of their services through teaching and consultancy.RESOURCESORI Education App - ORI Education shares online learning courses to those with an interest in osteoarthritis and orthopaedic surgery.

Did you know that 1 in 8 Australians live with osteoarthritis? It is one of the leading causes of pain and disability worldwide. On this special episode, we hear from previous guests on common misconceptions and beliefs about osteoarthritis, the importance of staying physically active, behaviour change, and driving change in osteoarthritis.If you are interested, you can listen to the full episodes:“Common Misconceptions and Beliefs about Osteoarthritis” with A/Prof Ben Darlow (Season 6, Ep. 16)“Walking for Joint Health” with Dr Sarah Kobayashi (Season 6, Ep. 12)"Tips for behaviour change for diet and exercise" with Dr Shannon Mihalko (Season 4, Ep. 1)"Driving change in osteoarthritis - strategies, barriers and consumer power" with Louise Hardy (Season 6, Ep. 7)RESOURCESMyOA.org.au - Additional resourcesCONNECT WITH USJoin one of our trials https://www.osteoarthritisresearch.com.au/current-trialsInstagram: @profdavidhunterTwitter: @ProfDavidHunter @jointactionorgEmail: hello@jointaction.infoWebsite: www.jointaction.info/podcastIf you enjoyed this episode, don't forget to subscribe to learn more about osteoarthritis from the world's leading experts!

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. Dr David Parker is an experienced orthopaedic knee specialist and co-founder of the Sydney Orthopaedic Research Institute (SORI). He is passionate about sport and is actively involved with international orthopaedic and sports medicine organisations and has extensive experience with athletes of all levels from recreational to elite. Dr Parker has authored over 100 peer-reviewed publications and many textbook chapters and has been awarded the Australian Orthopaedic Association Prize for Research. RESOURCESJournal articlesTotal knee replacement after high tibial osteotomy: time-to-event analysis and predictorsCONNECT WITH USJoin one of our trials https://www.osteoarthritisresearch.com.au/current-trialsTwitter: @ProfDavidHunter @jointactionorgEmail: hello@jointaction.infoWebsite: www.jointaction.info/podcastIf you enjoyed this episode, don't forget to subscribe to learn more about osteoarthritis from the world's leading experts!

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.RESOURCESJournal articlesNuclear receptors as potential drug targets in osteoarthritisInterplay between genetics and epigenetics in osteoarthritisRecent developments in emerging therapeutic targets of osteoarthritisCONNECT WITH USTwitter: @ProfDavidHunter @jointactionorgEmail: hello@jointaction.infoWebsite: www.jointaction.info/podcastIf you enjoyed this episode, don't forget to subscribe to learn more about osteoarthritis from the world's leading experts!

On this week's episode of Joint Action discover how ultra-processed foods may be silently contributing to osteoarthritis. Dr Gabby Joseph joins us to discuss her research research linking poor diet quality to greater knee pain, poorer physical function and thinner knee cartilage. Dr Gabby Joseph is a scientist and statistician with over 20 years of experience leading research funded by the US government at the University of California San Francisco, Her work focuses on musculoskeletal imaging, predictive modelling, and clinical study design, with a focus on applying advanced statistical and machine learning methods to improve patient outcomes She is the co-Director of The University of California's Clinical & Translational Musculoskeletal Imaging group and passionate about making sense of complex data so that it can be used to improve real-world care.

Did you know your beliefs about osteoarthritis could be making your symptoms worse? In this re-aired episode from Season 5, Episode 1 of Joint Action, physiotherapist and health communication expert Dr Ben Darlow joins us to explore how common misconceptions - like “wear and tear” or “bone on bone” - can limit your activity and shape your treatment choices. We discuss the power of language, the importance of hope, and how better understanding can help you take control of your health. Whether you're living with osteoarthritis, supporting someone who is, or working in healthcare, this conversation is a must-listen.RESOURCESLiving with osteoarthritis is a balancing act: an exploration of patients' beliefs about knee painThe osteoarthritis knowledge scaleCONNECT WITH USTwitter: @ProfDavidHunter @jointactionorgEmail: hello@jointaction.infoWebsite: www.jointaction.info/podcastIf you enjoyed this episode, don't forget to subscribe to learn more about osteoarthritis from the world's leading experts!
