BACKGROUND This study assessed the influence of preoperative mental health on functional outcomes and satisfaction, and the change in mental health after hallux valgus surgery. METHODS 383 patients who underwent scarf osteotomy were analyzed. Visual analogue scale (VAS), American Orthopaedic Foot & Ankle Society score (AOFAS) and SF-36 were assessed at 6 months and 2 years. The cohort was stratified into patients with and without psychological distress (i.e. SF-36 Mental Component Summary [MCS] <50 vs ≥50). RESULTS After adjusting for demographics and baseline scores, VAS and AOFAS were poorer in the distressed group at 6 months. However, there was no difference in scores at 2 years and a similar proportion of patients were satisfied. SF-36 MCS in distressed patients significantly improved, but remained lower compared to non-distressed patients at follow-up. CONCLUSIONS Patients with psychological distress undergoing hallux valgus surgery had poorer short-term outcomes, but these differences resolved at 2 years.
