COMPUTATIONAL SIMULATIONS-OPTIMIZATION OF UHMWPE KNEE ARTHROPLASTY ABRASIVE WEAR

Abstract

Today, total knee artificial implants constitute (TKA) a high-demanding prostheses in biomechanical/surgical-orthopedics industry. Abrasive TKA linear wear model-algorithm computational simulations are developed and presented for ultra-high molecular weight polyethylene (UHMWPE). This material is widely used for TKA implants. The implemented mathematical model is the classical/modified Archard’s model modified for TKA linear abrasion. The algorithms for Integer and Integral Formulation are explained. For computational intelligence simulations, selected literature experimental data, both in vitro and in vivo, is set within programming software. 3D Imaging-processing computational simulations software in 3D are designed with Graphical Optimization and Interior Optimization techniques. Million Cycles (Mc) results for Linear Wear, in numerical dataset and 3D simulations image-processing graphs are demonstrated and compared to literature database. Useful Biotribology/Biomaterials and Biomedical TKA clinical/manufacturing applications are briefed.
