Abstract

Highlights: Patients with an AOFAS of 88.5 consider their symptom state to be acceptable. AOFAS had good discriminative ability to determine if a PASS was achieved. Thresholds showed minimal variation with age, gender, BMI and baseline scores. PASS responders were 11 times more likely to be satisfied. Abstract: Background: This study aimed to define the patient acceptable symptom state (PASS) for the American Orthopaedic Foot & Ankle Society score (AOFAS) following hallux valgus surgery. Methods: 548 patients underwent hallux valgus surgery and had AOFAS assessed preoperatively, 6 months and 2 years postoperatively. Responses to an anchor question were used as external criterion in receiver operating characteristics (ROC) analyses to define PASS thresholds. Results: In total, 429 patients (78.3%) reported their current state as acceptable. Areas under the curve (AUC) for ROCs were 0.71−0.81 for all analyses. PASS threshold was 88.5 at 2 years (sensitivity 64%, specificity 85%). Sensitivity analyses revealed that the threshold was robust. Conclusions: Patients with an AOFAS of 88.5 consider their postoperative symptom state to be acceptable. This knowledge will enable clinicians to identify patients who have attained a satisfactory functional status after hallux valgus surgery.
