“…For semi-automatic registration, the repeatability of the method was investigated by Kanhonou et al and was shown to be very good with values inferior to 1 mm and 1 • [28]. These values are slightly better than ours which could be expected due to the use of image processing to assist the registration but should be completed by an evaluation of the accuracy in physiologic configurations to ensure the unbiased nature of the measurement.…”

“…The registration can be made manually and femoro-tibial joint kinematics derived from this procedure were previously used as a reference to evaluate and compare several tracking methods with marker cluster [25] or to test an automatic process based on image processing [26]. Some authors also proposed a semiautomatic method based on image processing to perform this registration, which has been evaluated in two studies [27,28]. However, in these studies, the quantification of the accuracy of the method relied on the use of simulated radiographs of 3D models virtually positioned in different configurations.…”

Highlights• The EOS system allows the sequential kinematic analysis of the femoro-tibial joint. • The reliability of the registration of 3D model on 2D views has been quantified. • The accuracy of the registration is inferior to 1.6 mm and 0.4 • . • The repeatability of the registration is 0.3 • , 2.1 • and 1.6 • , for the rotations. • The repeatability of the registration is inferior to 1.8 mm for the translations. Graphical abstract AbstractBackground: Several methods can be used to assess joint kinematics going from optoelectronic motion analysis to biplanar fluoroscopy. The aim of the present work was to evaluate the reliability of the use of biplane radiography to quantify the sequential 3D kinematics of the femoro-tibial joint.Methods: Bi-planar X-rays (EOS imaging) of 12 lower limbs (6 specimens in vitro and 6 subjects in vivo) were taken for various knee flexion angles. 3D personalized models of the femur and the tibia were registered on each pair of views. To quantify the bias, the kinematic parameters calculated from the registered models were compared to those obtained from the tripods embedded in the specimens. Intra and inter-operator repeatability of each parameter were assessed from the registrations made by 3 operators in vivo.Results: In vitro, the bias of the tibia pose estimation obtained from the registration method was inferior to 1.6 mm and 0.4 • . In vivo, the repeatability of the sequential kinematic parameters was inferior to 0.3 • , 2.1 • and 1.8 • , for respectively flexion, varus-valgus and medial-lateral rotation and inferior to 1.8 mm for translations.Conclusion: Compared to simple fluoroscopy, the accuracy of our method based on sequential images was of the same order of magnitude, with better results for the translation in the frontal plane. The low dose of radiation of the EOS system offers promising prospects for a clinical use of this method to assess the femoro-tibial sequential kinematics.

“…3D meshes of the tibia and femur were also reconstructed from the five biplane radiographs [17][18]. This reconstruction process gives an accuracy of the positions and orientations of the femur and tibia of less than 0.3±0.3° and 0.3±0.2 mm respectively [18]. CT-scan meshes were matched with the corresponded EOS meshes using an iterative closest point algorithm.…”

“…The quasi-static squat consisted of 4 positions of knee flexion and was standardized with the same proprioceptive jig used during the dynamic squat. The method used to obtain the 3D knee models for these 4 positions is detailed in Kanhonou et al (2014) and presents an accuracy and a precision about 0.3° and 0.3 mm in terms of positions and orientations of knee bones. Calculation of distance maps was the same as detailed above.…”
