Height/Length (H/L) ratio of the osteonecrotic femoral head of both groups, comparing operated right side to native left side

		Treated group N = 7	Control group N = 6
Right femoral head	Mean ± SD	0.51 ± 0.06	0.44 ± 0.06
	Range	0.37–0.56	0.31–0.53
Left femoral head	Mean ± SD	0.52 ± 0.07	0.53 ± 0.06
	Range	0.46–0.62	0.45–0.64
P value (right/left)		>0.05	0.03

Height/Length ratio, compare the height/length (H/L) ratio of the femoral heads.

P value was calculated by comparing the right and left femoral heads using Wilcoxon signed-rank test.

N, number of rats; Mean ± SD, mean ± standard deviation; range, minimum–maximum.
