The aim of this study was to investigate the risk factors for knee pain in the elderly. Seventy-six community-dwelling elderly women underwent an ultrasound examination of their knees. We compared the results of knee pain among the groups allocated according to the presence of osteophyte and effusion. Our results showed that the group with a copresence of osteophyte and effusion had a significantly higher presence of knee pain than the other groups. A combination of osteophyte and effusion provides a better indication for the risk of knee pain.
