The following parameters were assessed at 6 and 12 weeks, 9 months, and 5 years postoperatively: the American Orthopaedic Foot & Ankle Society (AOFAS) Forefoot Score, a visual analog scale (VAS) score for pain, and a patient-satisfaction score. In addition, several radiographic parameters for hallux valgus correction and joint degeneration were collected. Range of motion was also assessed.
