Joint Action

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.

Can identifying the right patients and the right endpoints transform how we test new osteoarthritis treatments? On this week's episode of Joint Action, we unpack what the FNIH Biomarkers Consortium has learned so far, and how their latest phase aims to deliver biomarkers that can make disease-modifying OA drug trials smaller, faster, and more likely to succeed.

Dr. Virginia Byers Kraus is a Professor of Medicine, Pathology, and Orthopaedic Surgery at Duke University School of Medicine. A rheumatologist and translational scientist, her research focuses on osteoarthritis and biomarker development as part of the international FNIH Biomarkers Consortium.

Peter G. Mesenbrink, Ph.D., is Executive Director of Biostatistics at Novartis and industry co-chair of the FNIH Biomarkers Consortium. With expertise in adaptive trial design, surrogate endpoint development, and data sharing policy, he is a frequent collaborator across industry, regulatory, and academic communities.

Dr. Jamie Collins is a biostatistician at Brigham and Women's Hospital and Associate Professor of Orthopaedic Surgery at Harvard Medical School. As lead statistician for the FNIH OA Biomarkers Consortium, her research focuses on strengthening osteoarthritis clinical trials through innovative trial design and prognostic enrichment.

Knee osteoarthritis doesn’t just affect joints—it can limit people’s ability to participate fully in work and daily life, shaping their long‑term wellbeing and productivity. In this week's episode of Joint Action we are joined by Jason Jin and Ilana Ackerman to explore how knee osteoarthritis influences workforce participation.

Dr Xingzhong (Jason) Jin is a conjoint research fellow at UNSW and the managing director of Precision Statistics Medtech Consulting. He is a musculoskeletal epidemiologist and health data scientist with a desire to bridge the gap between research and real-world healthcare impacts.

Professor Ilana Ackerman is a Research Professor at the School of Public Health and Preventive Medicine at Monash University and Deputy Director of the Musculoskeletal Health Unit. She is a musculoskeletal epidemiologist and an experienced orthopaedic physiotherapist and has led an important program of clinical and population-based research designed to quantify the personal and societal burden of hip and knee osteoarthritis, forecast trends in arthritis and joint replacement surgery, and evaluate the outcomes of joint replacement. She has also been involved in the development of multiple policy and guideline initiatives for osteoarthritis.

Tai Chi is a gentle, low-impact exercise that combines slow, controlled movements with balance and mindfulness. In this week’s episode of Joint Action, we are joined by Julia Zhu to discuss the evidence behind Tai Chi and its benefits for people living with knee osteoarthritis.

Julia Zhu is a physiotherapist and PhD student at the Centre for Health, Exercise & Sports Medicine at the University of Melbourne. She recently submitted her PhD, which focused on developing and evaluating a self-directed online intervention for people with osteoarthritis in a clinical trial, where she developed the RETREAT trial that investigated at the effects of an online Tai Chi program. She has an interest in bridging the gap between research and practice and to drive impact with innovation.

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.
