Finite element analysis of circumferential crack behavior in cement-femoral prosthesis interface

► SIFs demonstrated adverse relationship along with distal end of cement layer. ► Intensive value of KI happened at the corner of cement at the distal part. ► Push off, single leg stance presented the maximum SIFs in the hoop direction. ► KI, KIII were enhanced 89.5%, 65.9% and 63.7%, 56.5% in lateral and medial.
