Knee Replacement Simulation Including Large Displacement and Viscoelastic Effects

Human total joint replacement has become a common place procedure in the past decade, principally to eliminate pain in patients affected by osteoarthritis of the knee, hips, shoulder and spine. While in the past, this was done mostly for older patients with reduced mobility, more recently these replacements are being done for much younger, much more active people. As a result, the artificial joints need larger ranges of motion and are subject to much higher loads, while being required to last longer in place.
