Computational Prediction of in Vivo Wear in Total Knee Replacements
نویسنده
چکیده
INTRODUCTION Wear of ultra-high molecular weight polyethylene (UHMWPE) in total knee replacements remains a major limitation to the longevity of these clinically successful devices [1]. Improvements in sterilization techniques over the past decade have reduced oxidative degradation of the UHMWPE bearing, with potentially dramatic long-term reductions in fatigue-related pitting and delamination wear. However, abrasiveadhesive or “mild” wear mechanisms remain, with the potential to generate large numbers of submicron debris particles of osteolytic potential [2].

Computational wear prediction of a total knee replacement from in vivo kinematics.
Wear of ultra-high molecular weight polyethylene bearings in total knee replacements remains a major limitation to the longevity of these clinically successful devices. Few design tools are currently available to predict mild wear in implants based on varying kinematics, loads, and material properties. This paper reports the implementation of a computer modeling approach that uses fluoroscopica...
متن کاملInvestigation of Wear Behavior of Biopolymers for Total Knee Replacements Through Invitro Experimentation
The average life span of knee prosthesis used in Total Knee Replacement (TKR) is approximately 10 to 15 years. Literature indicates that the reasons for implant failures include wear, infection, instability, and stiffness. However, the majority of failures are due to wear and tear of the prosthesis. The most common biopolymer used in TKR is Ultra High Molecular Weight Polyethylene (UHMWPE). Pr...
متن کاملThe effect of insert conformity and material on total knee replacement wear
The mean average life is increasing; therefore, there is a need to increase the lifetime of the prostheses. To fulfil this requirement, new prosthetic designs and materials are being introduced. Two of the design parameters that may affect wear of total knee replacements, and hence the expected lifetime, are the insert conformity and material. Computational models have been used extensively for...
متن کاملIn-silico wear prediction for knee replacements--methodology and corroboration.
The capability to predict in-vivo wear of knee replacements is a valuable pre-clinical analysis tool for implant designers. Traditionally, time-consuming experimental tests provided the principal means of investigating wear. Today, computational models offer an alternative. However, the validity of these models has not been demonstrated across a range of designs and test conditions, and several...
متن کاملA comprehensive combined experimental and computational framework for pre-clinical wear simulation of total knee replacements
A more robust pre-clinical wear simulation framework is required in order to simulate wider and higher ranges of activities, observed in different patient populations such as younger more active patients. Such a framework will help to understand and address the reported higher failure rates for younger and more active patients (National_Joint_Registry, 2016). The current study has developed and...
