Biplane radiography data collection and processing. A Participants will walk on a treadmill while B synchronized biplane radiographs will be collected at 100 images per second (70 kV, 125 mA, 1 ms exposure per image). C CT scans of the residual femur will be collected and D used to create 3D bone models. E 3D bone pose will be determined using an automated volumetric model-based tracking process that matched digitally reconstructed radiographs to the original radiographs. F Six degree-of-freedom kinematics, including bone motion relative to the socket, will be calculated from late swing through push-off
