The relationship between knee osteoarthritis and femoral distal cortical bone thickness. case control study from the matsudai knee osteoarthritis survey

Abstract

Purpose: Knee osteoarthritis (OA) is a multifactorial disease and strongly affected by mechanical factors. We have previously reported that varus knee alignment is one of the risk factor for the development of knee OA in women. As knee OA progressed, the proximal medial tibial cortical bone thickness (MTCBT) is increased. However the relationship of its femur side with knee OA progression is unclearly. In this study, we investigated whether distal medial femoral cortical bone thickness (MFCBT) at baseline survey predicts the development of knee OA at follow-up survey.
