Abstract
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.
