Background: Literature is sparse on whether severity of hallux valgus affects outcomes of surgery. We thus aimed to evaluate the impact of hallux valgus severity on the clinical outcomes of surgery. Methods: 83 consecutive scarf osteotomies performed by a single surgeon for symptomatic hallux valgus between 2007 and 2011 were divided into 3 groups (mild, moderate, and severe) based on severity of their preoperative hallux valgus using the hallux valgus and intermetatarsal angles. Outcomes were assessed using the visual analog scale (VAS) for pain, 36-Item Short Form Health Survey physical functioning (SFPF) and mental health (SFMH) subscales, and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores. These were assessed preoperatively and at 6 months and 2 years postoperatively. Patient satisfaction was assessed at 6 months and 2 years postoperatively. Eleven (13.2%), 54 (65.1%), and 18 (21.7%) feet were in the mild, moderate, and severe groups, respectively. Results: There was no difference in preoperative VAS, SFPF, SFMH and AOFAS scores between the groups except for AOFAS scores for the second toe, which were poorer with increasing hallux valgus. Postoperatively, there was improvement across all outcome scores. VAS and AOFAS showed excellent scores, and patient satisfaction was high across all 3 groups (88.9%, 89.4%, and 86.7%). The severe group had slightly lower SFPF scores at 6 months (mild, 81.1; moderate, 84.0; severe, 74.3; P = .031) and 2 years postoperatively (mild, 93.4; moderate, 89.7; severe, 76.4; P = .005), and slightly poorer second toe scores for VAS (mild, 0.0; moderate, 0.1; severe, 1.2; P = .017) and AOFAS (mild, 94.7; moderate, 93.5; severe, 83.4; P = .043) at 2 years postoperatively. All other scores including patient satisfaction showed no between-group differences. Complication and revision rates between the groups were similar. Conclusion: Surgery for symptomatic hallux valgus lead to excellent outcomes and high patient satisfaction regardless of severity of deformity. Level of Evidence: Level III, comparative series.
