Table 2 Visual analogue scale (VAS) score results

Time	1 day pre-op	3 days post-op^a	3 months post-op^b	12 months post-op^c
VAS score	7.25 ± 1.02	2.73 ± 0.68	1.40 ± 0.44	0.63 ± 0.36

VAS scores are presented as mean number ± standard deviation (x ̅±s, n = 32). “^{a b c}” respectively represents the comparison between 3 days, 3 months and 12 months post-op and pre-op. Analysis using paired t-tests showed that P_a、P_a、P_c = 0.000<0.001, indicating significant differences were observed
