Influence of bone stress relaxation and abrasion on micromotions in uncemented femoral knee implants: a finite element study
m), though simulations failed to converge for two specimens due to limited bone-implant contact. These results underscore the importance of incorporating bone abrasion effects in FE models and highlight the need to further refine representations of bone plasticity, friction, and abrasion to improve micromotion predictions.
