Introduction:
Central sensitization (CS) is a pain amplification mechanism associated with poorer surgical outcomes. Its influence on hallux valgus (HV) surgery remains unclear. This study evaluates whether CS is associated with worse outcomes following Chevron and Akin osteotomies.
Methods:
Retrospective cohort study including 76 operated patients, divided according to their Central Sensitization Inventory (CSI) score (≥40 vs. <40). Functionality (AOFAS), pre-/postoperative pain (VAS), satisfaction (VAS), quality of life (EQ-5D-5L), and treatment response were analyzed.
Results:
Patients with CS showed worse functionality and quality of life, greater pain, and lower satisfaction (p<0.001). The most affected dimensions were pain, mobility, and daily activities (p<0.001). Both groups improved, particularly the non-CS group (p=0.001).
Conclusion:
CS is associated with poorer functional outcomes and may serve as a negative prognostic factor. Surgical intervention improves pain even in patients with CS.
