Background and Objective: Radiographic alignment and validated patient-reported outcomes (PROMs) both matter for hallux valgus surgery success. We quantified mid-term outcomes of two corrective osteotomies and examined whether radiographic correction predicts patient-reported gains. Methods: Retrospective single-centre study of 66 consecutive patients (73 feet; February 2012-March 2015) undergoing proximal crescentic osteotomy plus distal soft-tissue procedure (n = 41 feet) or distal Chevron osteotomy (n = 32 feet), per an institutional severity-based algorithm with Kirschner-wire fixation. Hallux valgus angle (HVA), intermetatarsal angle (IMA), Visual Analogue Scale (VAS), AOFAS Hallux Metatarsophalangeal-Interphalangeal Scale (AOFAS-HMI) and Foot and Ankle Outcome Score (FAOS) were assessed preoperatively and at last follow-up. Results: Mean follow-up was 17.7 +/- 9.9 months. HVA improved from 38.0 +/- 7.8 derece to 24.7 +/- 5.2 derece, IMA from 14.4 +/- 3.1 derece to 6.6 +/- 1.3 derece, VAS from 8.6 +/- 1.2 to 1.3 +/- 1.3 and, AOFAS-HMI from 49.7 +/- 17.2 to 88.3 +/- 8.2 (all p < 0.001). All five FAOS subscales improved (mean change +16.6 +/- 21.6 to +32.7 +/- 30.9 points; Cohen's d 0.78-1.26); 60.3-80.8% of feet reached the minimal clinically important difference and 53.4-86.3% a pre-specified acceptable-symptom-state threshold. DeltaFAOS-Pain correlated strongly with DeltaFAOS-ADL (r = 0.85, p < 0.001). Conclusions: Both techniques produced clinically meaningful improvements; patient-reported gains were not strongly determined by radiographic correction. Obtained with Kirschner-wire fixation and 4-week casting, these data provide a historical control dataset against which contemporary rigid-fixation and minimally invasive series can be audited. Level of Evidence: III, retrospective comparative study.
