Effect of Probiotic Supplements on Osteoarthritis Outcomes

Dysbiosis of the gut microbiota is believed to contribute to the development and progression of osteoarthritis (OA), suggesting a role for probiotics in the treatment of OA. Animal studies have shown that certain probiotic strains decrease the inflammatory responses, pain sensitization and OA progression. There are, however, few clinical studies in humans to support this. In this double-blinded randomized controlled trial we will investigate the effect of 6-months probiotic supplements compared to placebo on OA related outcomes in females with diagnosed knee OA.
