An abnormality of femoral anteversion (FA) is often recognized in patients with osteoarthritis of the hip joint (hip OA). And it is considered that rotation abnormality in the knee and the lower leg occurs as compensation, in cases of FA abnormality. The purpose of this study was to assess the magnitude and variability of FA and femoral condyle rotation (FCR) in order to identify the association between FA and FCR in female patients with hip OA who require total hip arthroplasty. A total of 174 hips from 174 hip OA patients undergoing THA were included in this study. All patients were Asian women (average age: 71.1 years). An equilateral correlation was accepted in FA and FCR. It was thought that FA abnormality might be accompanied by morphological rotation abnormalities of the knee joint. Caution is needed in considering femoral anteversion using the posterior condylar line. We must consider FA in patients undergoing THA after having considered the whole leg rotation.
