In order to critically evaluate the effect of surgical correction, a retrospective analysis of our patient cohort was performed. Hereby, special emphasis was set on the analysis of the pre- and post-operative equinus position of the hindfoot.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>Retrospectively, all patients (<jats:italic>n<\/jats:italic>\u2009=\u200982) after midfoot resection arthrodesis in Charcot type Sanders 2 or 3 were included. Complications were recorded, and the mean complication-free interval was calculated. Additionally, the calcaneal pitch as well as Meary\u2019s angle were measured pre- and post-operatively and in case of complications.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>Overall complication rate was 89%. Revision surgery was necessary in 46% of all patients. The mean complication-free interval was 285\u00a0days (0\u20131560\u00a0days). Calcaneal pitch and Meary\u2019s angle significantly improved after operation but returned to pre-operative values after onset of complications. Achilles tendon lengthening showed no significant effects on the mean complication-free interval.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>Operative treatment of Charcot arthropathy remains a surgical challenge with high complication rates. Surgical correction of equinus position has been highlighted for successful treatment but was not able to prevent complications in this study, which is demonstrated by the recurrent decrease of the calcaneal pitch in cases of reoperation. Therefore, as a conclusion of our results, our treatment algorithm changed towards primarily addressing the equinus malpositioning of the hindfoot by corrective arthrodesis of the hindfoot.\n<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00264-022-05567-y","type":"journal-article","created":{"date-parts":[[2022,9,22]],"date-time":"2022-09-22T08:04:14Z","timestamp":1663833854000},"page":"141-150","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["High rate of complications after corrective midfoot\/subtalar arthrodesis and Achilles tendon lengthening in Charcot arthropathy type Sanders 2 and 3"],"prefix":"10.1007","volume":"47","author":[{"given":"Markus","family":"Regauer","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Veronika","family":"Grasegger","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"F\u00fcrmetz","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrian Calvacanti","family":"Kussmaul","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wolfgang","family":"B\u00f6cker","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9439-7632","authenticated-orcid":false,"given":"Christian","family":"Ehrnthaller","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2022,9,22]]},"reference":[{"key":"5567_CR1","doi-asserted-by":"publisher","first-page":"43","DOI":"10.1016\/j.cpm.2016.07.006","volume":"34","author":"Y Alrashidi","year":"2017","unstructured":"Alrashidi Y, Hugle T, Wiewiorski M et al (2017) Surgical treatment options for the diabetic charcot midfoot deformity.
