Hydroxytyrosol is mainly found in olive leaves after hydrolysis of oleuropein and has anti-oxidant, anti-bacterial, and anti-inflammatory properties. The aim of this study was to investigate the effect of hydroxytyrosol for alleviating the pain in patients with gonarthrosis. We conducted a double-blind clinical trial in which hydroxytyrosol or placebo was administered to adult patients with gonarthrosis for 4 weeks. The group administered hydroxytyrosol showed significant improvement in the Japanese Orthopedic Association score (pain measurement index) and the visual analog scale score compared to the placebo group.
