“…Concerning the femoro-tibial joint, Zeighami et al reported RMS errors of in average 0.63 • for all rotations and 0.8 mm for all translations using the same modality (EOS system) and a semi-automatic method of registration [27]. These results are similar to the ones obtained in the present study ( Table 2) by using a manual method.…”

“…The apparent discrepancy of these results can be attributed to both the different experimental conditions and the choice of coordinate systems. In a study using the same modality and definition of femur and tibia coordinate systems, Zeighami et al reported an amplitude of medial rotation during the first 20 • of flexion of the knee of 11.8 • in average for ten healthy subjects close to the value obtained in the present study [27].…”

“…Most often, clinical quantification of knee kinematics is performed by motion capture of skin markers inducing a high uncertainty due to soft tissue artifact [10,43,44]. However, it can be expected that knee pathologies such as osteoarthritis or ligament injuries would modify the kinematics of the femoro-tibial joint [27]. The quantification of the kinematic pattern alteration, in particular for translation modification, requires very accurate techniques.…”

“…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.

“…However, recent methods could estimate knee contact parameters in weight-bearing conditions using either bi-plane fluoroscopy (Farrokhi et al, 2016;Farrokhi et al, 2014), or bi-plane low-dose radiography (Zeighami et al, 2017). Biplane imaging allows for a relatively small registration error and yields an estimation of CPs based on the concept of minimal bone-to-bone distance (Zeighami et al, 2017).…”

Contact point (CP) trajectory is a crucial parameter in estimating medial/lateral tibio-femoral contact forces from the musculoskeletal (MSK) models. The objective of the present study was to develop a method to incorporate the subject-specific CP trajectories into the MSK model. Ten healthy subjects performed 45 s treadmill gait trials. The subject-specific CP trajectories were constructed on the tibia and femur as a function of extension-flexion using low-dose bi-plane X-ray images during a quasi-static squat. At each extension-flexion position, the tibia and femur CPs were superimposed in the three directions on the medial side, and in the anterior-posterior and proximal-distal directions on the lateral side to form the five kinematic constraints of the knee joint. The Lagrange multipliers associated to these constraints directly yielded the medial/lateral contact forces. The results from the personalized CP trajectory model were compared against the linear CP trajectory and sphere-on-plane CP trajectory models which were adapted from the commonly used MSK models. Changing the CP trajectory had a remarkable impact on the knee kinematics and changed the medial and lateral contact forces by 1.03 BW and 0.65 BW respectively, in certain subjects. The direction and magnitude of the medial/lateral contact force were highly variable among the subjects and the medial-lateral shift of the CPs alone could not determine the increase/decrease pattern of the contact forces. The suggested kinematic constraints are adaptable to the CP trajectories derived from a variety of joint models and those experimentally measured from the 3D imaging techniques.

Cartilage contact characteristics of the knee during gait in individuals with obesity

Obesity increases the risk of knee osteoarthritis (OA). Knee joint contact characteristics have been thought to provide insights into the pathogenesis of knee OA; however, the cartilage contact characteristics in individuals with obesity have not been fully described. We conducted cartilage‐to‐cartilage contact analyses through high‐precision fluoroscopy imaging with subject‐specific magnetic resonance cartilage models. Twenty‐five individuals with obesity were recruited for this study, and previously published data consisted of eight nonobese individuals who were used as the comparator group. In both groups, knees were imaged by a dual fluoroscopic imaging system during treadmill walking, and the tibiofemoral cartilage contact locations were analyzed and described on the tibial plateau in the medial−lateral (ML) and anterior−posterior (AP) directions and on femoral condyle surfaces using contact angles in the sagittal plane and deviation angles in a plane perpendicular to the sagittal plane. On the medial tibial plateau, the ML contact locations in the individuals with obesity were located more medially than in the nonobese group throughout the stance phase. The medial plateau AP contact locations in individuals with obesity showed a different pattern compared with the nonobese group. The ML contact excursions on the medial plateau in the individuals with obesity were larger than in the nonobese group. These findings suggest that obesity affects the contact location mainly in the medial compartment, which explains, in part, the high prevalence of medial knee OA in the obese population.
