Given the lack of evidence available in our country regarding this subject, especially about this type of surgical technique, our paper aims to compare open and MIS approaches for chevron osteotomy. We evaluated the outcome and complications after 12 months. Materials and Methods: We undertook a prospective, randomized, controlled, single-center study between October 2017 and December 2020. The patients were randomized into two groups: one group that received percutaneous chevron osteotomy (MIS), and the other, open chevron osteotomy (OC). For clinical assessment, we determined the function and the level of pain using the Visual Analogue Scale (VAS) and The American Orthopaedic Foot and Ankle Surgery score (AOFAS). The VAS scale was measured before the surgical procedure, at discharge, and at 3 weeks, 6 weeks, 6 months, and 12 months after surgery. The AOFAS score was calculated preoperatively and after 6 months. The hallux angle (HVA) and intramedullary angle (IMA) were measured preoperatively, and at 6 weeks, 6 months and 12 months. Results: We included 26 cases in the open chevron osteotomy group (24 female, 2 male) and 24 in the MIS group (24 female, 0 male). Both groups demonstrated improvements regarding the IMA and HVA at the last follow-up without any significant differences between the groups at the final assessment. The VAS showed significantly better post-operative results for the MIS group at discharge (p &lt; 0.001) and 3 weeks (p &lt; 0.001), 6 weeks (p &lt; 0.001), and 6 months (p = 0.004) post-surgery. The AOFAS showed no significant differences either before or after surgery. Four cases with screw prominence were reported, three of which belonged to the MIS group. Only one case with metatarsalgia was found in the OC group. Conclusions: This paper demonstrates that minimally invasive chevron osteotomy has comparable results with open chevron osteotomy, even though surgical time and radiological exposure are significantly longer. More studies are required to evaluate the complications and the risk of recurrences.<\/jats:p>","DOI":"10.3390\/medicina58030359","type":"journal-article","created":{"date-parts":[[2022,3,1]],"date-time":"2022-03-01T21:25:14Z","timestamp":1646169914000},"page":"359","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Percutaneous Chevron Osteotomy: A Prospective Randomized Controlled Trial"],"prefix":"10.3390","volume":"58","author":[{"given":"Serban","family":"Dragosloveanu","sequence":"first","affiliation":[{"name":"Faculty of medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 020021 Bucharest, Romania"},{"name":"Department of Orthopaedics, \u201cFoisor\u201d Orthopaedics Hospital, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1200-379X","authenticated-orcid":false,"given":"Viola Maria","family":"Popov","sequence":"additional","affiliation":[{"name":"Faculty of medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 020021 Bucharest, Romania"},{"name":"Colentina Clinical Hospital Hematology Clinic, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1059-1532","authenticated-orcid":false,"given":"Drago\u0219-Corneliu","family":"Cotor","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics, \u201cFoisor\u201d Orthopaedics Hospital, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christiana","family":"Dragosloveanu","sequence":"additional","affiliation":[{"name":"Faculty of medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cristian Ioan","family":"Stoica","sequence":"additional","affiliation":[{"name":"Faculty of medicine, \u201cCarol Davila\u201d University of Medicine and Pharmacy, 020021 Bucharest, Romania"},{"name":"Department of Orthopaedics, \u201cFoisor\u201d Orthopaedics Hospital, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"14515","DOI":"10.1038\/s41598-021-93902-5","article-title":"Impact of quality of life related to foot problems: A case-control study","volume":"11","year":"2021","journal-title":"Sci.
