Dynamic finite element knee simulation for evaluation of knee replacement mechanics.
In vitro pre-clinical testing of total knee replacement (TKR) devices is a necessary step in the evaluation of new implant designs. Whole joint knee simulators, like the Kansas knee simulator (KKS), provide a controlled and repeatable loading environment for comparative evaluation of component designs or surgical alignment under dynamic conditions. Experimental testing, however, is time and cos...
متن کاملExplicit finite element modeling of kinematics and contact mechanics of artificial hip and knee joints
An explicit finite element method was applied to simultaneously predict both kinematics and contact mechanics of artificial hip and knee joints under normal walking condition. Mesh sensitivity and numbers of time interval were examined on the model prediction for an artificial hip joint under the condition of three-dimensional forces and rotations. Furthermore, the explicit method was used to p...
متن کاملEvaluating knee replacement mechanics during ADL with PID-controlled dynamic finite element analysis.
Validated computational knee simulations are valuable tools for design phase development of knee replacement devices. Recently, a dynamic finite element (FE) model of the Kansas knee simulator was kinematically validated during gait and deep flexion cycles. In order to operate the computational simulator in the same manner as the experiment, a proportional-integral-derivative (PID) controller w...
متن کاملFinite Element Modeling and Analysis of Prosthetic Knee Joint
Degenerative arthritis is a disease that affects the line cartilage of the knee joint. It causes severe pain in the joint and may require a replacement surgery of the affected knee with artificial components. Geometric complexity and non linearity of the materials of the knee make the analytical solutions of the mechanical behaviour of the knee joint difficult. The knee is the most complex join...
متن کاملFinite Element Modeling of Knee and Shoulder Ligaments
The medial collateral ligament (MCL) is the primary restraint to knee valgus rotation and a secondary restraint to anterior tibial translation. The anterior cruciate ligament (ACL) is a primary restraint to anterior tibial translation, but its contribution to valgus restraint was debated. To address this, a combined experimental and computational study was conducted to determine the effect of A...
