ABSTRACT

Knee osteoarthritis is a disabling disease, causing pain and reduced function.Orthoses are used to manage this problem, including knee braces and lateral wedge insoles. However, there is still controversy on which type of intervention is more effective. This systematic review and meta-analysis aimed toevaluate the effect of knee braces and lateral wedge insoles and compare their clinical outcomes onindividuals with medial knee osteoarthritis. We conducted the search strategy based on the population, intervention, comparison, andoutcome (PICO) method. We searched with PubMed, EMBASE, Web of Science, and Scopus databases for the related studies. The articles quality assessment was done based on the modified Downs and Black checklist. Totally, we chose 32 controlled trials, including 1.849 participants, for the final evaluation. Almosttwo-thirds of the studies had a moderate quality. The overall outcome suggested that both interventionshad improved pain and function. The difference between both interventions on pain reduction was not significant (standardized mean difference = 0.12, 95% confidence interval = 0.34 to 0.1) based on meta-analysis. Both knee brace and lateral wedge insole can improve pain and function in people with knee osteoarthritis. Using either separately or both of them together are effective.
