  1. Decrease of preoperative pain – percentage decrease of preoperative VAS, PD-Q score - painDETECT Questionnaire score, Screening results: No – Nociceptive - a total score of ≤12, a neuropathic pain component is unlikely, Un – result is unclear, a neuropathic pain component could be present, Ne – Neuropathic, a score of ≥19, a neuropathic component is likely, Number of cases and (%) – percentage of cases within main group. * - statistically significant difference between all three groups (P < .001, ANOVA with post-hoc analysis using the Fisher LSD test), # - statistically significant correlation between adequate groups (Group I – No, Group II – Un, Group III – Ne) (Cramer’s V = .66, Yates’Chi-square P < .001).
