Finite element has been used for more than four decades to study and evaluate the
mechanical behaviour total joint replacements. In Huiskes seminal paper “Failed innovation …

Current hip replacement femoral implants are made of fully solid materials which all have
stiffness considerably higher than that of bone. This mechanical mismatch can cause …

Revision surgeries of total hip arthroplasty are often caused by a deficient structural
compatibility of the implant. Two main culprits, among others, are bone-implant interface …

The new generation of hip metal-on-metal resurfacing arthroplasty (MMRA) devices have
now been implanted for more than 13 years in the centers that initiated the return to this …

A methodology is proposed to design a spatially periodic microarchitectured material for a
two-dimensional femoral implant under walking gait conditions. The material is composed of …

An appropriate method of application of the hip-joint force and stress analysis of the pelvic
bone, in particular the acetabulum, is necessary to investigate the changes in load transfer …

Stress shielding due to difference in stiffness of bone and implant material is one among the
foremost causes of loosening and failure of load-bearing implants. Thus far, femoral …

Femoral bone loss due to stress and strain shielding is a common problem in hip resurfacing
arthroplasty (HRA), which arises from the different stiffness of implant materials and the …

One of the major causes of implant loosening is due to excessive bone resorption
surrounding the implant due to bone remodelling. The objective of the study is to investigate …

Stress shielding–induced bone resorption around cementless acetabular components has
been indicated as a potential failure mechanism that may threaten long-term fixation. Using …
