This is a survey on 3-D dynamic and quasi-static human knee joint modeling. Anatomical surface representation, contact modeling, ligament structure, and solution algorithm are reviewed. Understanding knee joint biomechanics is important for total knee replacement and rehabilitation exercise design, ligament reconstruction, and cartilage damage. Knee models were proposed mostly in the last two decades. They aimed normal activities and rehabilitation exercises, and sought muscle, ligament, and joint contact forces. Consisting of two joints, tibio-femoral (TF) and patello-femoral (PF), the human knee 3-D models were PF, TF [1–3], and both TF and PF [4–7]. Models were static, quasi-static, and dynamic, including the entire, partial, or none of the ligament structure. Contact models of the knee were rigid or deformable. Both natural knees and replacement models were reported. Different groups of muscles were considered.

Joint Biomechanics

The objectives of the work reported in this article were to develop a novel 6-degree-of-freedom (DOF) robotic system for knee joint biomechanics, to complete a hybrid force-position control scheme, to evaluate the system performance, and to demonstrate a combined loading test. The manipulator of the system utilizes two mechanisms; the upper mechanism has two translational axes and three rotational axes while the lower mechanism has only a single translational axis. All axes were driven with AC servo-motors. This unique configuration results in a simple kinematic description of manipulator motion. Jacobian transformation was used to calculate both the displacement and force/moment, which allowed for a hybrid control of the displacement of, and force/moment applied to, the human knee joint. The control and data acquisition were performed on a personal computer in the C-language programming environment with a multi-tasking operating system. Preliminary tests revealed that the clamp-to-clamp compliance of the system was smaller in the vertical (Z) and longitudinal (Y) directions (0.001 mm/N) than in lateral (X) direction (0.003 mm/N). The displacement error under the application of 500 N of load was smallest in the vertical direction (0.001±0.003 mm (mean±SD), and largest in the lateral direction (0.084±0.027 mm). Using this test system, it was possible to simulate multiple loading conditions in a human knee joint in which a cyclic anterior force was applied together with a coupled, joint compressive force, while allowing natural knee motion. The developed system seems to be a useful tool for studies of knee joint biomechanics.

Fluid Pressurization

The mechanical response of the knee joint has been simulated using finite element methods with elastic material models [1–4]. Fluid pressurization in articular cartilage and menisci has not been considered in the anatomically accurate joint modeling until recently [5–7]. We have recently considered stress relaxation and creep behavior of human knees. The objective of the present study was to investigate the mechanics of the femoral cartilage under cyclical knee compression. We are particularly interested in the determination of loading versus unloading patterns for the fluid pressure and flow, as well as the influence of the loading frequency on the fluid pressurization.

Joint Biomechanics

The human knee joint is very critical and complex joint of human body which is responsible for our optimal daily functions. It consists of various bones – femur, tibia, patella, fibula, different ligaments, cartilages, menisci and muscles. FEM is a very useful tool for the analysis of knee joint and various knee replacement products. In the knee replacement surgery a proper understanding of knee joint biomechanics is essential. Because of certain limitations of experimental studies, FEM analysis process is playing a significance role for prominent understanding of knee biomechanics and produced an effective and impressive tool for total knee replacement (TKR/TKA) or partial knee replacement (PKR/PKA). The aim of this paper is to give a review on FEM analysis of human knee joint and knee prosthesis devices and how much adequate this method for these type of analysis.

In the surgical process of total knee replacement (TKR), it is well known that the three types of failureswhich are; a) unable to reproduce normal knee function, b) bone-implant interface failure c) wear duringuse. These failures are certainly due to the motion and the load that influence the prosthesis components.In this study, the modelling questions of the human knee joint will be discussed in relation only to themultibody dynamics models. Firstly, a summary is presented about the relevant literature, where themodels with their different features are presented and evaluated. The existing models are mainly focusedon the investigation of the ligaments (linear of non-linear properties), the description of the contact path,and contact forces during the motion, kinematics (rotation, abduction and adduction) and even the wearmechanism of the knee joint. The primal advantages of the multibody dynamics models are the easyadaptability in the mechanical parameters to carry out simulations and the connection with CAE programsthat helps the design of new prostheses. A new multibody model is also presented by the authors.

This paper is a review of static and dynamic models of the human knee joint. Both phenomenological and anatomically based models are discussed. The phenomenological models can be classified into two groups: first, models which consider the human knee to be a simple hinge joint and, second, rheological models. The simple hinge models have generally been used in larger models developed to predict human body dynamics during gait activities. The rheological models, which describe the knee as an equivalent viscoelastic hinge, have been used to describe the response of the knee joint during dynamic loading conditions. Anatomically based models have been used to predict the kinematics and kinetics of the knee and its structural components. The majority of kinetic models have treated static and quasistatic equilibrium conditions, and only a few have addressed nonequilibrium dynamic loading. In reviewing the static and quasistatic models, we have divided them into four groups. First, models developed to determine the forces in the muscles and the ligaments at the knee joint during various activities, second, models developed to determine the forces in the ligaments as a function of joint position, third, models used to determine the contact stresses between the femur and the tibia, and, fourth, more comprehensive models developed to study the stiffness and load–displacement characteristics of the knee joint which include both ligamentous structures and the geometric constraints of the knee. In our survey, we found few models of the patello-femoral joint. A more complete model of the human knee joint describing the interactions between the tibia, femur, patella, and fibula still needs to be developed. On the other hand, the geometric and mechanical properties of a single real knee, required to validate any model are not presently available.

In this paper the knee joint biomechanics during squat exercises is studied. Using an acquisition system based on electro-goniometers, measurements of flexion-extension knee angle during squat movement on a sample group of healthy subjects are performed. For each subject the curves of knee squat angle are normalized and the mean squat cycle of each subject and the final medium cycle are determined. The phase plane portraits are used to characterize the kinematics of the biomechanical system. Using ADAMS software, the forces components and the resultant connection force during squat cycle in the human knee joint are determined.

3D Model Reconstruction

Reconstruction of a 3D model for human knee joint is the basic step for its kinematics and dynamics analysis. To make further research on knee joint modeling, we present a new method to reconstruct 3D knee joint models based on magnetic resonance image (MRI). This method consists of steps as pretreatment of the images, the region growing for segmentation and the contour interpolation or the grey value interpolation and so on. The resulting 3D knee joint model are used for dynamics analysis of human knee joint after being imported into the finite-element platform which includes the tibia, the femur, the meniscus and the cartilages. The 3D model provides the possibility for the research on the movement roles and mechanics characteristics of the knee joint.
