Fig. 14From: Mechanical strength assessment of a drilled hole in the contralateral cortex at the end of the open wedge for high tibial osteotomyCritical angle obtained using FKM approach (Cortical bone as semi-ductile): The critical angle was the angle obtained when the equivalent stress in the specimen reached the assessed static strength. The higher critical angles were obtained for specimens with drilled holes (SWHE and SWHA)Back to article page
