“…Our study complements these previous studies by documenting the primary and coupled motions occurring in response to applied varus/valgus moments through additional flexion angles throughout a functional 90°arc of flexion. Finally, our results agree with Roth et al, who showed that the limits of varus/valgus motion increase with flexion [17].…”

“…A more comprehensive understanding of the coronal plane kinematics of the native knee in terms of primary and coupled motions is important for surgeons who wish to restore normal knee function [16,17]. In this study involving native cadaver knees, we sought to determine 1) does the degree of coronal plane laxity, in terms of both primary and coupled motions, change as the knee is ranged from 0 to 90°; 2) is coronal plane laxity (both primary and coupled motions) increased particularly during the mid-flexion range (30°to 45°); and 3) is coronal plane laxity symmetric under varus/valgus loading as the knee is ranged from 0 to 90 degrees?…”

“…This study aimed to simulate a CTKI using a dynamic FE model and considering the close-to-physiological muscle and ankle joint forces. The femoral external rotation and posterior translation of the CTKI with both cruciate ligaments retained were in good agreement with that of healthy knee measured by Murakami et al 31 and other tibiofemoral motion ranges and patterns were also consistent with previous results from the literature 35,36 .…”

Customised total knee replacement could be the future therapy for knee joint osteoarthritis. A preliminary design of a customised total knee implant based on knee anatomy was studied in this article. To evaluate its biomechanical performance, a dynamic finite element model based on the Oxford knee rig was created to simulate a squatting motion. Unlike previous research, this dynamic model was simulated with patient-specific muscle and joint loads that were calculated from an OpenSim musculoskeletal model. The dynamic response of the customised total knee implant was simulated under three cruciate ligament scenarios: both cruciate ligaments retained, only anterior cruciate ligament removed and both cruciate ligaments removed. In addition, an off-the-shelf symmetric total knee implant with retained cruciate ligaments was simulated for comparison analysis. The customised total knee implant with both cruciate ligaments retained showed larger ranges of femoral external rotation and posterior translation than the symmetric total knee implant. The motion of the customised total knee implant was also in good agreement with a healthy knee. There were no big differences in the tibiofemoral compressive forces in the customised total knee implant model under the three scenarios. These forces were generally consistent with other experimental and simulation results. However, the customised total knee implant design resulted in larger tibiofemoral compressive force than the symmetric total knee implant after 50° knee flexion, which was caused by the larger tibiofemoral relative motion.

“…Furthermore, the set-up has limited degrees of freedom to control knee movement as is the case in existing gait simulators [1,[3][4][5]. In particular, our set-up lacks to simulate the fontal and transverse plane motion that occurs at the knee and which was observed to be quite significant [23]. However, as for the reduced forces, our results have shown that kinematics similar to in vivo can still be achieved despite these simplifications.…”

Despite their well known limitations, in vitro experiments have several benefits over in vivo techniques when exploring foot biomechanics under conditions characteristic for gait.In this study, we present a new set-up for dynamic in vitro gait simulation that integrates a numerical model for generating the tibial kinematics control input and we present an innovative methodology to measure full 3D joint kinematics during gait simulations. The gait simulator applies forces to the tendons. Tibial kinematics in the sagittal plane is controlled using a numerical model that takes into account foot morphology. The methodology is validated by comparing joint rotations measured during gait simulation with those measured in vivo. In addition, reliability and accuracy of the control system as well as simulation input and output repeatability are quantified. The results reflect good control performance and repeatability of the control inputs, vertical ground reaction force, center of pressure displacement and joint rotations and translations. In addition, there is a good correspondence to in vivo kinematics for most patterns of motion at the ankle, subtalar and Chopart's joints. Therefore, these results show the relevance and validity of including specimen-specific information for defining the control inputs.
