Therefore, this study is to investigate the clinical efficacy and safety of a new \u201cU\u201d\u2010shaped staple in the treatment of postoperative ankle valgus of congenital pseudarthrosis of the tibia (CPT).<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>According to the inclusion and exclusion criteria, 33 patients with postoperative ankle valgus of CPT were treated with new \u201cU\u201d\u2010shaped staples from May 2013 to September 2019. The deformity of ankle valgus was gradually corrected by implanting a new \u201cU\u201d\u2010shaped staple on the medial side of the distal tibia. Clinical indexes such as the operation time, intraoperative bleeding and hospital stay were observed. Tibiotalar angle was selected as the evaluation index of ankle valgus. American Orthopedic Foot &amp; Ankle Society (AOFAS) scale was used for clinical evaluation of ankle function. The tibiotalar angle, deformity correction rate and complications were evaluated by preoperative, postoperative and last follow\u2010up imaging data. Student's <jats:italic>t<\/jats:italic>\u2010test was used for statistical analysis.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Thirty\u2010three patients, including 12 males and 21 females were included. All the patients were followed up for at least 14\u2009months, with an average of 35\u2009months. The average operation time was 23 (15\u201340) min, the average amount of intraoperative bleeding was 7.5 (4\u201310) mL, and the average hospital stay was 4.2 (3\u20136) days. The intraoperative tibiotalar angles of all patients were 74.2\u00b0\u2009\u00b1\u20094.6\u00b0, the tibiotalar angle were 86.8\u00b0\u2009\u00b1\u20094.9\u00b0 when internal fixation was removed, and the tibiotalar angles at the last follow\u2010up were 84.3\u00b0\u2009\u00b1\u20095.9\u00b0. The average orthopedic rate was 0.68\u00b0 per month. No patients suffered from serious complications such as screw prolapse, osteomyelitis, wound infection, etc. Postoperative wound pain complications occurred in two patients, which were relieved after conservative treatment. The AOFAS score improved from 46.2\u2009\u00b1\u20099.4 before the operation to 74.6\u2009\u00b1\u20095.7 at the last follow\u2010up (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01).
