Background: In the clinical evaluation of femoroacetabular impingement (FAI), there is a lack of quantitative, reliable and informative assessment methods for the overall functional capability of an individual.
Objective: We compared clinical and radiological measurements of the hip joint with a new methodology based on the concept of 3-dimensional reachable workspace using Microsoft Kinect.
Methods: We assessed the correlation between the alpha angle of Nötzli on full-length radiographs and the clinical internal rotation.
