Importance of trabecular anisotropy in finite element predictions of patellar strain after Total Knee Arthroplasty
Highlights • 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...

description | Highlights • 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. |
