Statistical Shape Modelling (SSM) has the potential to reliably measure changes in OA. SSM can be applied to both DXA and radiographic images. DXA has some advantages since it can measure bone mineral density (BMD) and has a very low radiation dose, however, weight bearing imaging is not possible in DXA. Previous studies investigating knee positioning for DXA have focussed on BMD precision; to optimise knee positioning in DXA for use with shape modelling studies we tested 3 positioning protocols. For ultimate success, this must combine the needs of the patient, radiographer and the researcher, so questions about comfort and ease of use were assessed alongside measures of precision and image appearance. The purpose of this study was to compare 3 positioning protocols (neutral, wedge and full-leg) for measuring knee morphology from Dual Energy X-ray Absorptiometry (DXA) images.
