| description | Background: Currently, more than 150 surgical techniques have been described for the treatment of hallux valgus. The abundance of techniques indicates that there is no technique that has been designated as a gold standard. In recent years, a particular interest in the use of minimally invasive techniques has grown. The aim of this study was to prospectively compare clinical, radiologic, and postoperative outcomes between the MICA technique and open chevron technique over a 1-year follow-up period. Methods: Between January 2016 and August 2020, data were prospectively collected from consecutive patients preoperatively and at 6 weeks, 3 months, and 12 months following minimally invasive chevron and Akin (MICA) or open chevron osteotomies. Radiographic outcomes were measured using weightbearing radiographs preoperatively and at 3 and 12 months postoperatively. Clinical outcomes were measured using the American Orthopaedic Foot & Ankle Society (AOFAS), Manchester-Oxford Foot Questionnaire (MOXFQ), VAS (visual analog scale), Foot Function Index (FFI), Foot and Ankle Outcome Score (FAOS), and Euro-QoL-5D (EQ5D) questionnaires. Results: Of the 68 patients, 42 patients (62%) underwent a MICA surgery and 26 patients (38%) underwent open chevron osteotomy. Both groups showed significant improvement in HVA, IMA, and DMAA at the 1-year follow-up. Our findings show that both clinical and radiologic outcomes of the MICA technique are comparable to the conventional open technique. No significant differences were found in clinical outcomes (VAS, AOFAS, MOXFQ, FFI, and FAOS), complication rate, and operative times. Conclusion: These results show that MICA is a safe alternative for chevron osteotomy. The clinical and radiologic outcomes of these 2 techniques by 12 months are comparable. Level of Evidence: Level II, prospective cohort study. |
