Defining the load bearing axis of the lower extremity obtained from anterior-posterior digital radiographs of the whole limb in stance

The purpose of this study was to evaluate the reliability of inter-and intra-observer assessments of the mechanical alignment of the lower extremities with digitally computed radiographs of an anterior-posterior view of the whole leg using a new computer-assisted method.Load bearing axis deviation of the lower extremities was quantitatively measured by three examiners in 105 knees of 73 subjects who had osteoarthritis of the knee with a...
