Objective. Enhancing exercise adherence over the longer term is an important goal in self-management of knee osteoarthritis (OA). Following an initial period of more intensive exercise supervision, this study investigated whether 2 additional physiotherapy visits improved outcomes with continued home exercise over a subsequent 24-week period. Methods. A total of 78 people with medial knee OA (mean +/- SD age 62.1 +/- 6.9 years, mean +/- SD body mass index 29.4 +/- 4.0 kg/m(2), and radiographic disease severity 19% mild, 49% moderate, and 32% severe) who completed a 12-week physiotherapist-supervised exercise trial were randomly allocated to 2 30-minute physiotherapy booster sessions (delivered by 8 physiotherapists in private clinics) or no booster sessions for the subsequent 24 weeks. All participants were asked to continue home exercises 4 times weekly. Primary outcomes were change in pain, using a 100-mm visual analog scale, and self-reported physical function, measured using the Western Ontario McMaster Universities Osteoarthritis Index. Participants and physiotherapists were unblinded to group allocation, although participants were blinded to the study hypothesis. Results. A total of 74 participants (95%) completed the trial. There was no significant difference between groups for change in pain (mean difference [95% confidence interval (95% CI)] 0.7 mm [-9.4, 8.0]; P = 0.88) or physical function (-0.3 units [95% CI -4.0, 3.5]; P = 0.88). The mean +/- SD percentage of home exercise sessions completed was 56% +/- 34% in the booster group and 51% +/- 37% in the control group (P > 0.05). Conclusion. Two booster sessions with a physiotherapist did not influence pain or physical function outcomes, or measures of home exercise adherence. These findings suggest other more effective strategies are needed to maximize longer-term adherence with the aim to achieve greater improvements in clinical outcomes from exercise in this patient population.
