About this book

This book develops and analyses computational wear simulations of the total ankle replacement for the stance phase of gait cycle. The emphasis is put on the relevant design parameters. The book presents a model consisting of three components; tibial, bearing and talar representing their physiological functions.

Chapter 2. Contact Pressure of Total Ankle Replacement (TAR)
Abstract
Three-dimensional (3D) models of a right ankle TAR have been created to represent Bologna-Oxford (BOX) TAR model. Finite element analysis of ankle stance phase of gait cycle was developed to simulate the static response behaviour and extract the data in determining the contact pressure on contact surface of the bearing and talar components. Sliding distance was determined by predominate motion of plantar/dorsi flexion of ankle stance phase gait cycle. Validity of contact analysis was conducted to make sure consistent, accurate, and therefore dependable procedures.

Chapter 3. Wear of Total Ankle Replacement (TAR)
Abstract
Computational wear simulation of TAR were developed using the Archard’s wear model. Wear rate is the ultimate performance indicator of wear. The parameter such as ankle joint loading and kinematics were used in determining wear rates. Historically, wear performance was assessed by experimental means of clinical and physical simulators. Therefore, this present studies was used the finite element method to predict wear of TAR with adaptive re-meshing technique. The wear sensitivity test was conducted to determine the wear update interval and converge at 0.5 million cycles for update interval.

Chapter 4. Effect of Design Parameter Towards Wear Generation
Abstract
Wear performance was affected by several factors to contribute towards wear generation. Prospect of minimize wear is needed further study by using optimize design parameter. Inevitability to optimize the design is to improve the understanding of reducing wear in human ankle joint. Change in implant dimension has been suggested, may result in better implant lifespan. The effect of design parameter towards wear generation were analysed the thickness and radial contact of meniscal bearing.

Chapter 5. Conclusion
Abstract
This study developed the computational wear model using finite element analysis in order to predict wear on total ankle replacement (TAR). The Bologna-Oxford (BOX) TAR was analysed with loading and boundary condition applied for the stance phase of ankle gait cycle. Result shows that the linear wear depth, h and volumetric wears, V were within the wear range of BOX TAR model reported in the literature. Therefore, the computational method using finite element analysis developed can be used to predict wear on total ankle replacement (TAR).
