BACKGROUND: Telerehabilitation is perceived as less effective than in-person care for musculoskeletal problems. We aimed to determine if physiotherapy video conferencing consultations were non-inferior to in-person consultations for chronic knee pain. METHODS: In this non-inferiority randomised controlled trial, we recruited primary care physiotherapists from 27 Australian clinics. Using computer-generated blocks, participants with chronic knee pain consistent with osteoarthritis were randomly assigned (1:1, stratified by physiotherapist and clinic) in-person or telerehabilitation (ie, video conferencing) physiotherapist consultations. Participants and physiotherapists were unmasked to group assignment. Both groups had five consultations over 3 months for strengthening, physical activity, and education. Primary outcomes were knee pain (on a numerical rating scale of 0 to 10) and physical function (using the Western Ontario and McMaster Universities osteoarthritis index of 0 to 68) at 3 months after randomisation. Primary analysis was by modified intention-to-treat using all available data. This trial is registered with the Australian and New Zealand Clinical Trials Registry, ACTRN12619001240134. FINDINGS: Between Dec 10, 2019, and June 17, 2022, 394 adults were enrolled, with 204 allocated to in-person care and 190 to telerehabilitation. 15 primary care physiotherapists were recruited. At 3 months, 383 (97%) participants provided information for primary outcomes and both groups reported improved pain (mean change 2.98, SD 2.23 for in-person care and 3.14, 1.87 for telerehabilitation) and function (10.20, 11.63 and 10.75, 9.62, respectively). Telerehabilitation was non-inferior for pain (mean difference 0.16, 95% CI -0.26 to 0.57) and function (1.65, -0.23 to 3.53). The number of participants reporting adverse events was similar between groups (40 (21%) for in-person care and 35 (19%) for telerehabilitation) and none were serious. INTERPRETATION: Telerehabilitation with a physiotherapist is non-inferior to in-person care for chronic knee pain.
