Knee osteoarthritis (OA) is common in middle‐aged and elderly people. It causes degeneration and destruction of articular cartilage and surrounding joint structures, which often limits activities of daily living (ADLs). The global prevalence of symptomatic knee OA is reported to be approximately 13% in women and 10% in men aged 60 and older. In Japan, 54.6% of people aged 40 and older are reported to have radiographic knee OA, including many who are asymptomatic, and the prevalence increases with age. Knee OA can lead to restrictions in ADLs, declines in quality of life, and subsequent detriments to mental health. The relationship between depression and knee OA has been gaining attention recently, with some recent studies showing associations between knee OA and development of depressive symptoms, but most of these studies focused on radiographic changes rather than actual symptoms in their assessments of knee OA. Few have examined directly how knee pain and function relate to depressive symptom.Depression is also a common condition in later life, with 13.5% of people aged 55 and older reported to be affected. Depressive symptoms cause a decline in physical activity levels and everyday social and psychological function. Depressive symptoms in individuals with knee OA
