This study aimed to investigate the effect of flatfoot correction on the ankle joint of patients without osteoarthritis.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Thirty-five patients (24 men and 11 women; mean age 17.5 years) who underwent lateral column lengthening for flatfoot deformities were included. The mean postoperative follow-up period was 20.5 months (standard deviation [SD]: 15.7 months). Radiographic indices were measured pre- and postoperatively, including anteroposterior (AP) and lateral talo-first metatarsal angles, naviculocuboid overlap, position of the articulating talar surface, and lateral talar center migration. Postoperative changes in the radiographic indices were statistically analyzed.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>There was significant postoperative improvement in flatfoot deformity in terms of AP and lateral talo-first metatarsal angles (p&lt;0.001 and p&lt;0.001, respectively) and naviculocuboid overlap (p&lt;0.001). On lateral radiographs, the talar articulating surface dorsiflexed by 7.3% (p&lt;0.001), and the center of the talar body shifted anteriorly by 0.85 mm (p&lt;0.001) postoperatively.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>Flatfoot correction using lateral column and Achilles tendon lengthening caused dorsiflexion and an anterior shift of the articular talar body in patients without osteoarthritis. Correction of flatfoot deformity might affect the articular contact area at the ankle joint. The biomechanical effects of this change need to be investigated further.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0286013","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T18:06:09Z","timestamp":1698948369000},"page":"e0286013","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":3,"title":["Effect
