The purpose of the present study was to evaluate the radiographic outcome of opening-wedge high tibial osteotomy (OWHTO) using this new internal fixator. Sixty OWHTOs were performed in patients with medial compartment osteoarthritis and varus deformity (28 males and 23 females). Patients' mean age was 60.4 years. Preoperative and postoperative radiographs were obtained. The paired t-test was used to evaluate the differences over time with respect to radiographic variables. Union of the osteotomy gap was obtained in all patients, and no implant breakage was found. On anterior\u2013posterior radiographs, a significant difference was observed (p\u2009&lt;\u20090.01) between the preoperative and postoperative mean values of femorotibial angles (179.6\u2009\u00b1\u20093.2 vs. 170.6\u2009\u00b1\u20092.5\u2009degrees), weight-bearing line ratios (23.8\u2009\u00b1\u200913.5 vs. 60.5\u2009\u00b1\u200911.5%), anatomical medial proximal tibial angles (84.8\u2009\u00b1\u20092.5 vs. 91.0\u2009\u00b1\u20092.6\u2009degrees), and joint line coverage angles (3.6\u2009\u00b1\u20092.0 vs. 2.4\u2009\u00b1\u20091.7\u2009degrees). On lateral radiographs, posterior tibial slopes were 11.5\u2009\u00b1\u20093.9\u2009degrees preoperatively and 12.2\u2009\u00b1\u20094.0\u2009degrees postoperatively (p\u2009&lt;\u20090.01), and Insall\u2013Salvati ratios were 1.04\u2009\u00b1\u20090.12 preoperatively and 1.06\u2009\u00b1\u20090.13 postoperatively (p\u2009=\u20090.24). Performing OWHTO using a new internal fixator with a wedge-shaped spacer achieves adequate correction of lower limb alignment without implant-related complications. This is a Level IV, case series study.<\/jats:p>","DOI":"10.1055\/s-0039-1700977","type":"journal-article","created":{"date-parts":[[2020,1,14]],"date-time":"2020-01-14T00:16:23Z","timestamp":1578960983000},"page":"997-1001","source":"Crossref","is-referenced-by-count":0,"title":["Radiographic
