文摘

Aim of study was to estimate effect of isotropy/anisotropy on patellar strain after Total Knee Arthroplasty. We compared finite element results of 17 patellae, in physiological loading. Compared to anisotropy, isotropy overestimated stain up to 4 times. This strain difference was maximum with low density patellae.
