Exploring Experiences of People With Knee Osteoarthritis Who Received a Physiotherapist-Delivered Dietary Weight Loss and Exercise Intervention: A Mixed Methods Study.

Objective: Explore the experiences of people with knee osteoarthritis (OA) who received a very low energy diet (VLED) and exercise program from a physiotherapist.

Methods: Mixed methods study involving questionnaires (n = 42) and semistructured interviews (n = 22) with randomized control trial participants with knee OA who had received a 6-month physiotherapist-delivered VLED weight loss and exercise intervention. Questionnaires measured participant satisfaction and perceptions about physiotherapist's skills/knowledge in delivery of the dietary intervention (measured on 5-7 point Likert scales).

Alternative models to support weight loss in chronic musculoskeletal conditions: effectiveness of a physiotherapist-delivered intensive diet programme for knee osteoarthritis, the POWER randomised controlled trial.

Objectives: To determine if physiotherapists can deliver a clinically effective very low energy diet (VLED) supplementary to exercise in people with knee osteoarthritis (OA) and overweight or obesity.

Methods: 88 participants with knee OA and body mass index (BMI) >27 kg/m were randomised to either intervention (n=42: VLED including two daily meal replacement products supplementary to control) or control (n=46: exercise). Both interventions were delivered by unblinded physiotherapists via six videoconference sessions over 6 months.
