[Abstract] Knee osteoarthritis (KOA) pain makes KOA become one of the main diseases causing functional disability. KOA pain will cause all levels of pain projection neurons in the central nervous system to be in a highly sensitive state, and ultimately induce the functional remodeling of the pain regulation loop in the brain. Resting state functional magnetic resonance imaging (rs-fMRI) makes the mechanism of brain function remodeling of KOA pain intuitive, and provides strong support for the study of central pathological mechanism. Based on the summary of relevant literature in recent 5 years, this paper found that the current research on the mechanism of KOA pain brain function remodeling based on rs-fMRI is mostly focused on local brain regions. It is necessary to further reveal its remodeling mechanism from the perspective of brain function integration with the help of multiple functional and structural imaging methods, and clarify the functional connectivity changes of various brain regions and brain networks caused by KOA pain. This article introduces the development of rs-fMRI and its specific application in the mechanism of KOA pain brain function remodeling, and discusses and prospects its research status, in order to provide new ideas for the clinical management and mechanism research of KOA pain.
