This study compared patient-reported recovery as regards sexual function and driving ability following the KF versus the LF for primary sacrococcygeal PSD. METHODS: This multicenter retrospective cohort study (FLARE study) included employed, sexually active patients who underwent surgery for primary PSD (July 2017-July 2024). The primary outcome was time to sexual activity resumption; the secondary outcome was time to resumption of driving. Outcomes were assessed at 1 year using a structured Likert-scale questionnaire. Kaplan-Meier curves and Cox regression analyses with adjustment were used. RESULTS: A total of 352 patients were divided into 176 KF and 176 LF. KF patients resumed sexual activity earlier (2.88 ± 0.7 vs. 4.58 ± 1.1 weeks; mean difference -1.7 weeks, 95% CI -1.89 to -1.49, p < 0.001). KF reported significantly less pain, less avoidance, and lower analgesic use during sex. LF reported lower sexual satisfaction (mean 3.94 vs. 2.15; mean difference -1.78, 95% CI -2.02 to -1.53). KF resumed driving earlier (median 9 vs. 19 days; r = 0.7, large effect, p < 0.001) and had longer sitting tolerance (OR 0.3, 95% CI 0.2-0.4, p < 0.001). LF had higher pain while sitting (mean Likert 4 vs. 2; mean difference of -1.94, 95% CI -2.19 to -1.68), higher VAS pain (median 4 vs. 2; r = 0.5), greater need for cushions/analgesics, and more driving-related work/social limitations (all p < 0.001). Time to resume sexual activity and driving was significantly shorter for KF. On multivariable analysis, LF was independently associated with delayed return to sexual activity (adjusted OR 4.02, 95% CI 2.1-7.5, p < 0.001) and delayed return to driving (adjusted OR 2.8, 95% CI 1.5-5.2, p < 0.001). CONCLUSIONS: In this retrospective cohort, KF may be associated with significantly faster return to sexual and driving activity compared with LF. These results underscore the importance of incorporating patient-centered functional outcomes into surgical decision-making for PSD.
