Abstract
<jats:sec><jats:title>Background:</jats:title><jats:p> Hallux valgus (HV) treatment is continuously evolving, and no definitive treatment can be recommended. Osteotomies are the main surgical choice for these deformities, but no clear role for soft tissue procedures is available. </jats:p></jats:sec><jats:sec><jats:title>Objective:</jats:title><jats:p> To perform a retrospective comparison of the radiographic and clinical outcomes of 2 groups of patients with severe HV operated with the same osteotomy technique but differing on the type of lateral release. </jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p> Two groups of patients with symptomatic moderate to severe HV deformities were operated with the same proximal metatarsal osteotomy, which differed on the type of lateral release: group 1 had limited transarticular lateral capsule release (n = 62), and group 2 complete lateral release, including capsule, adductor tendon, and intermetatarsal (IM) ligament (n = 57). We recorded the American Orthopaedic Foot & Ankle Society (AOFAS) score, HV and IM angles, first metatarsal shortening, concomitant metatarsal shortening osteotomies (Weil), Akin osteotomies, and complications. </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> The postoperative AOFAS score in group 1 was similar to that of group 2. The HV and IM angles improved in both groups with no significant difference. The multivariate analysis showed no influence of any variable analyzed on HV or IM angle improvement. Regarding AOFAS score improvement, a limited lateral release was associated with a higher increase in AOFAS score ( P = .019). </jats:p></jats:sec><jats:sec><jats:title>Conclusion:</jats:title><jats:p> No studies are available to identify which soft tissue structures are involved in HV deformities nor which have to be released, if any. A limited transarticular release can provide similar clinical and radiologic outcomes when compared with a classic open lateral release. </jats:p></jats:sec><jats:sec><jats:title>Level of Evidence:</jats:title><jats:p> Level IV, case series. </jats:p></jats:sec>
