“…In order to investigate the effect of different loading conditions on the process of bone remodelling related to osseointegration, three loading conditions were simulated: (a) a normal walking condition, with the load applied in both transverse and vertical directions; (b) a transverse loading condition, and (c) a transverse loading condition with 40% load reduction. The data were obtain from the work of Kutzner et al [23]. 1/8 of the peak load was applied in the current model, in order to convert the force obtained from 3D to 2D model.…”

Purpose The tibial drill-guide angle in anterior cruciate ligament (ACL) reconstruction influences the tunnel placement and grafttunnel force, and is potentially associated with post-operative tunnel widening. This study aimed to examine the effect of the drill-guide angle on the stress redistribution at the tibial tunnel aperture after anatomic single-bundle ACL reconstruction. Methods A validated finite element model of human knee joint was used. The tibial tunnel with drill-guide angle ranging from 30°to 75°was investigated. The post-operative stress redistribution in tibia under the compressive, valgus, rotational and complex loadings was analysed.Results Compressive loading played a leading role on the stress redistribution at intra-articular tibial tunnel aperture. After ACL reconstruction, stress concentration occurred in the anterior and posterior regions of tunnel aperture while stress reduction occurred in the lateral and posteromedial regions under the compressive loading. Stress redistribution was partially alleviated by using the drill-guide angle ranging from 55°to 65°. Conclusions The present study quantified the effect of bone tunnel drill-guide angle on the post-operative stress redistribution. This phenomenon potentially contributed to tunnel widening. A tunnel drill-guide angle ranging from 55°to 65°was proposed based on the biomechanical rationale. It could serve as a helpful surgical guide for ACL reconstruction.

“…The knee joint motion is much more com-plexed including both translations and rotations during normal gait motions. In daily activity, such as normal non-pathological gait, the human knee joint is subjected to significant loads with peak values well-above the subject's body weight [3,10,13,15,21]. These load patterns are very complex, because of several external forces exist (ground reaction force, mass and acceleration forces from the foot and the shank) which are counterbalanced by the forces acting inside the joint, such as the tibiofemoral contact forces and forces generated by the muscles to either keep the balance or to generate a motion.…”

Evaluation of a geometry-based knee joint compared to a planar knee joint

Today neuromuscular simulations are used in several fields, such as diagnostics and planing of surgery, to get a deeper understanding of the musculoskeletal system. During the last year new models and datasets have been presented which can provide us with more in-depth simulations and results. The same kind of development has occurred in the field of studying the human knee joint using complex three dimensional finite element models and simulations. In the field of musculoskeletal simulations, no such knee joints can be used. Instead the most common knee joint description is an idealized knee joint with limited accuracy or a planar knee joint which only describes the knee motion in a plan. In this paper, a new knee joint based on both equations and geometry is introduced and compared to a common clinical planar knee joint. The two kinematical models are analyzed using a gait motion, and are evaluated using the muscle activation and joint reaction forces which are compared to in-vivo measured forces. We show that we are able to predict the lateral, anterior and longitudinal moments, and that we are able to prediction better knee and hip joint reaction forces.
