Abstract

Finite element models of the growth plate were created that included chondrocytes with primary cilia at different depths within the reserve zone (RZ) between the epiphyseal subchondral bone-plate (SBP) and proliferative zone (PZ). Cilia were oriented along the direction of bone growth. Loading was applied to include 10% compression or tension across the growth plate cartilage. Under compression, axial strains in the cilium body were compressive and increased with cell depth between the SBP (-20%) to the PZ (-40%); cilium membrane radial strains were compressive (-5%) near the SBP but became tensile (10%) near the PZ. Under distraction, axial strains in the cilium body were tensile and increased from the SBP (12%) to the PZ (28%); cilium membrane radial strains were tensile (4%) at the SBP but became compressive (-12%) at the PZ. Reserve zone chondrocyte cilia perceive amplified strains that are sensitive to cell depth and direction of loading.
