Table 4: Pain as VAS-scores (mean ± SD) in 90 patients who returned the VAS list.
| Group | Mean pain | Total pain duration (days) | Day 1 | Day 3 | Day 7 |
| Standard (n = 30) | 2.4 ± 1.2 | 7.2 ± 5.0 | 3.5 ± 1.9 | 2.7 ± 1.9 | 2.8 ± 1.9 |
| Preoperative (n = 30) | 3.0 ± 2.1 | 6.4 ± 4.3* | 3.7 ± 2.6 | 4.2 ± 2.5 | 3.8 ± 2.9 |
| Postoperative (n = 30) | 2.9 ± 1.4 | 9.7 ± 5.3* | 4.1 ± 2.3 | 4.2 ± 2.6 | 3.1 ± 2.3 |
| All (n = 90) | 2.9 ± 0.17 | 7.8 ± 5.0 | 3.8 ± 2.3 | 3.7 ± 2.6 | 3.2 ± 2.3 |
VAS: Visual Analogue Score, pain duration = days until VAS = 0, *significant difference (p < 0.05; ANOVA and Bonferroni post hoc testing).
