Should you lose weight or have your knee replaced? On this week's episode of Joint Action, Professor Marius Henriksen joins Professor David Hunter to discuss the INKA randomised controlled trial, which set out to test whether an intensive dietary weight loss program could deliver results comparable to knee arthroplasty for people with knee osteoarthritis who are eligible for surgery.

Professor Marius Henriksen is a clinical professor of physiotherapy at the Faculty of Health and Medical Sciences, Copenhagen University, and head of musculoskeletal research at the Parker Institute at Copenhagen University Hospital in Denmark. His primary research focus is clinical research in osteoarthritis, with an emphasis on non-pharmacological management including exercise and weight loss.

When we say a treatment works for knee osteoarthritis, it is worth asking: works for whom? On this week's episode of Joint Action, Professor Christian Barton unpacks the blind spots in osteoarthritis research, exploring who has and hasn't been included in the evidence base for first-line care, and what that means for the patients we treat every day.

Prof Christian Barton is a physiotherapist and implementation scientist at La Trobe University, where he leads key projects including GLA:D Australia and TREK. With additional training in communications and implementation science, his research focuses on bridging the gap between evidence and practice in osteoarthritis, knee, and running injury care. He also consults privately at Complete Physio Richmond.
