In Vitro Fatigue Failure of Cemented Acetabular Replacements: A Hip Simulator Study

N. P. Zant, P. Heaton-Adegbile, J. G. Hussell, J. Tong
Journal: Journal of Biomechanical Engineering
Publisher: ASME
Article Type: Research Papers
J Biomech Eng. April 2008, 130(2): 021019.

Predicting Knee Replacement Damage in a Simulator Machine Using a Computational Model With a Consistent Wear Factor

Dong Zhao, Hideyuki Sakoda, W. Gregory Sawyer, Scott A. Banks, Benjamin J. Fregly
Journal: Journal of Biomechanical Engineering
Publisher: ASME
Article Type: Research Papers
J Biomech Eng. February 2008, 130(1): 011004.
https://doi.org/10.1115/1.2838030
Published Online: February 5, 2008
...Dong Zhao; Hideyuki Sakoda; W. Gregory Sawyer; Scott A. Banks; Benjamin J. Fregly Wear of ultrahigh molecular weight polyethylene remains a primary factor limiting the longevity of total knee replacements (TKRs). However, wear testing on a simulator machine is time consuming and expensive, making...
