^*The values are given as the mean and standard error of the mean.

^†A significant difference in water content in the anulus fibrosus was found between the control and tethered groups (p < 0.001).

^‡A significant difference in glycosaminoglycan content in the left side of the anulus was found between the control and tethered groups (p < 0.001).
