As modern society enters the age of an aging population, the prevalence of knee OA continues to increase, which necessitates multi-faceted research. Although there are studies on exaggeration of bodily sensations, depression, kinesiophobia and functional status in patients with knee OA, there are deficiencies in correlating these factors with each other and in directing evaluation and treatment programs. Based on this, this study aims to demonstrate the relationship between the level of exaggeration of bodily sensations, psychological-functional status and perceived pain level in patients with knee pain due to knee OA.
