Materials and Methods: Twenty-five patients, ages 42 to 71 years, underwent MDCO with FDL tendon transfer for stage II posterior tibial tendon dysfunction. Follow-up was 2.6 to 10.2 years. Preoperative and postoperative Japanese Society for Surgery of the Foot (JSSF), Foot Function Index, and SF-36 scores and physical and radiographic findings were compared. Eight measures of foot alignment were obtained from weight-bearing radiographs at 3, 6, 9, and 12 months after surgery and every 6 months thereafter. Differences in scores and values over time were analyzed statistically. Results: Average JSSF scores improved from 59 preoperatively to 91.3 postoperatively ( p &lt; .001). The only x-ray parameters that improved significantly and showed maintenance of the surgical correction were the lateral talometatarsal (LTMT) and tibiocalcaneal (TBC) angles. With preoperative LTMT and TBC angles of &gt;25\u00b0 and &gt;15\u00b0, respectively, correction was inadequate. Conclusions: It was concluded that indications for MDCO with FDL tendon transfer in cases of adult-acquired flatfoot are a preoperative LTMT angle of &lt;25\u00b0 and hindfoot coronal alignment (TBC angle) of &lt;15\u00b0. <\/jats:p><jats:p> Level of Evidence: IV, Case Series <\/jats:p>","DOI":"10.3113\/fai.2012.0940","type":"journal-article","created":{"date-parts":[[2012,12,18]],"date-time":"2012-12-18T18:39:48Z","timestamp":1355855988000},"page":"940-946","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":74,"title":["Outcome of Medial Displacement Calcaneal Osteotomy for Correction of Adult-Acquired Flatfoot"],"prefix":"10.1177","volume":"33","author":[{"given":"Hisateru","family":"Niki","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Marianna University School of Medicine, Kanagawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takaaki","family":"Hirano","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Marianna University School of Medicine, Kanagawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirokazu","family":"Okada","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Marianna University School of Medicine, Kanagawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moroe","family":"Beppu","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, St. Marianna University School of Medicine, Kanagawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2012,11,1]]},"reference":[{"key":"bibr1-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1016\/j.clinbiomech.2009.01.009"},{"key":"bibr2-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1016\/j.fcl.2007.03.003"},{"key":"bibr3-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2007.1115"},{"key":"bibr4-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(91)90220-4"},{"key":"bibr5-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110079701800915"},{"key":"bibr6-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110078100200106"},{"key":"bibr7-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1007\/s11420-006-9017-0"},{"key":"bibr8-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.5435\/00124635-200807000-00005"},{"key":"bibr9-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2009.1168"},{"key":"bibr10-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110070202301205"},{"key":"bibr11-FAI.2012.0940","volume-title":"Manual of SF-36v2 (Japanese Version)","author":"Fukuhara S","year":"2004"},{"key":"bibr12-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198668010-00012"},{"key":"bibr13-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1097\/01.blo.0000157658.17056.46"},{"key":"bibr14-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110070102200802"},{"key":"bibr15-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110079902001212"},{"key":"bibr16-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-198902000-00022"},{"key":"bibr17-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110079501601108"},{"key":"bibr18-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1177\/107110070402500701"},{"key":"bibr19-FAI.2012.0940","doi-asserted-by":"publisher","DOI":"10.1007\/s00776-005-0937-1"},{"key":"bibr20-FAI.2012.0940","first-page":"457","volume":"10","author":"Niki H","year":"2005","journal-title":"I: Development of standard rating system.
