A finite element model of the human knee joint for the study of tibio-femoral contact.
As a step towards developing a finite element model of the knee that can be used to study how the variables associated with a meniscal replacement affect tibio-femoral contact, the goals of this study were 1) to develop a geometrically accurate three-dimensional solid model of the knee joint with special attention given to the menisci and articular cartilage, 2) to determine to what extent bony...
متن کاملThe Study of Menisci Effect on Tibio-femoral Kinematics in a Computational Knee Joint
The menisci are important knee structures that are often ignored in computational models of the knee. Previous work on this project has shown that representation of the menisci significantly reduces the contact forces and pressures on the articulating surfaces of the tibia and femur [1]. The purpose of this study was to examine the significance of the menisci on tibio-femoral kinematics. Improv...
متن کاملNonlinear surrogate modeling of tibio-femoral joint interactions
Musculoskeletal modeling can predict muscle forces and the resulting motion and loading during human ambulatory activities. A better understanding of the loading environment on hard and soft tissues can enhance our understanding of ligament injury and prevention, tissue engineering, prosthetic design, osteoporosis, and osteoarthritis. The current state-of-the-art in movement simulation is to us...
متن کاملHow the stiffness of meniscal attachments and meniscal material properties affect tibio-femoral contact pressure computed using a validated finite element model of the human knee joint.
In an effort to prevent degeneration of articular cartilage associated with meniscectomies, both meniscal allografts and synthetic replacements are subjects of current interest and investigation. The objectives of the current study were to (1) determine whether a transversely isotropic, linearly elastic, homogeneous material model of the meniscal tissue is necessary to achieve a normal contact ...
متن کاملDoes joint line elevation after revision knee arthroplasty affect tibio-femoral kinematics, contact pressure or collateral ligament lengths? An in vitro analysis
INTRODUCTION Correct restoration of the joint line is generally considered as crucial when performing total knee arthroplasty (TKA). During revision knee arthroplasty however, elevation of the joint line occurs frequently. The general belief is that this negatively affects the clinical outcome, but the reasons are still not well understood. MATERIAL AND METHODS In this cadaveric in vitro stud...
