Results of multiple linear regressions to fit the maximum strain at the apex for the nine tibias analysed in Part 1 of the finite element analysis.

Apex location	Variable	Coefficient (% strain/mm)	p‐Value	R 2 correlation coefficient
Fixed apex: w = 10 mm, h = 17 mm	Tibia size	${\beta }_1=-0.73$	0.033	0.74
	Fibular head location	${\beta }_2=-1.57$	0.017
With scaling: w = 13%, h = 23% of the medial‐lateral width	Tibia size	${\beta }_1=-0.03$	0.88	0.73
	Fibular head location	${\beta }_2=-1.35$	0.011
