Preoperative anxiety and depression symptoms are associated with poorer clinical outcomes following corrective surgery for adult equinocavovarus foot.

Purpose: This study aimed to investigate the preoperative psychological status of adult patients with equinocavovarus foot deformity and to examine the association between preoperative anxiety/depressive symptoms and the clinical outcomes of corrective surgery in this population. Methods: A retrospective analysis was conducted on 103 adult patients who underwent corrective surgery for equinocavovarus foot at Xi'an Honghui Hospital between March 2014 and July 2023. Baseline data were collected. Patient psychological status, ankle-hindfoot function, pain, and quality of life were assessed preoperatively and at the final follow-up using the Hospital Anxiety and Depression Scale (HADS), the American Orthopedic Foot & Ankle Society (AOFAS) ankle-hindfoot score, the Visual Analog Scale (VAS), and the 36-Item Short Form Health Survey (SF-36). Based on preoperative HADS scores, patients were categorized into an anxiety/depression group (Group A) and a non-anxiety/depression group (Group B). The two groups were compared with respect to baseline characteristics (gender, age, disease duration, BMI, follow-up duration), clinical outcomes, and the degree of improvement in all assessment metrics. Results: A total of 83 patients completed the follow-up, among whom 38 (45.78%) exhibited preoperative anxiety/depression symptoms. No significant differences were found in baseline characteristics between the two groups (all P > 0.05). At the final follow-up, both groups showed significant improvement in VAS, AOFAS, SF-36 (PCS/MCS), and HADS (A/D) scores compared to their preoperative baselines (all P < 0.001). Intergroup comparisons revealed that Group A had significantly lower AOFAS and SF-36 (PCS/MCS) scores, and significantly higher VAS and HADS (A/D) scores than Group B, both preoperatively and at the final follow-up (all P < 0.001). Regarding the degree of improvement, Group A demonstrated a smaller magnitude of improvement in VAS (P < 0.01), AOFAS (P < 0.01), and SF-36 PCS (P < 0.001) compared to Group B. Conversely, Group A showed a greater improvement in SF-36 MCS and HADS (A/D) scores (all P < 0.001). Conclusions: While surgery improved all outcomes, patients with preoperative anxiety/depression exhibited persistently worse clinical scores. Their improvement profile was distinct: smaller gains in pain and physical function but greater mental health improvement. Addressing preoperative psychological status may optimize comprehensive outcomes.
