Therefore, medial opening-wedge HTO is a technically demanding procedure despite the use of 2-dimensional (2-D) navigation.<\/jats:p>\n          <jats:p>\n            The authors evaluated the posterior tibial slope pre- and postoperatively in patients who underwent navigation-assisted opening-wedge HTO and compared posterior slope changes for 2-D and 3-dimensional (3-D) navigation versions. Patients were randomly divided into 2 groups based on the navigation system used: group A (2-D guidance for coronal alignment; 17 patients) and group B (3-D guidance for coronal and sagittal alignments; 17 patients). Postoperatively, the mechanical axis was corrected to a mean valgus of 2.81\u00b0 (range, 1\u00b0\u20135.4\u00b0) in group A and 3.15\u00b0 (range, 1.5\u00b0\u20135.6\u00b0) in group B. A significant intergroup difference existed for the amount of posterior tibial slope change (\u0394 slope) pre- and postoperatively (\n            <jats:italic>P<\/jats:italic>\n            =.04).\n          <\/jats:p>\n          <jats:p>Opening-wedge HTO using navigation offers accurate alignment of the lower limb. In particular, the use of 3-D navigation results in significantly less change in the posterior tibial slope postoperatively than does the use of 2-D navigation. Accordingly, the authors recommend the use of 3-D navigation systems because they provide real-time intraoperative information about coronal, sagittal, and transverse axes and guide the maintenance of the native posterior tibial slope.<\/jats:p>","DOI":"10.3928\/01477447-20120919-60","type":"journal-article","created":{"date-parts":[[2012,10,1]],"date-time":"2012-10-01T17:39:14Z","timestamp":1349113154000},"page":"60-63","source":"Crossref","is-referenced-by-count":12,"title":["Posterior Tibial Slope in Medial Opening-wedge High Tibial Osteotomy: 2-D Versus 3-D Navigation"],"prefix":"10.3928","volume":"35","author":[{"given":"Ji Hyeon","family":"Yim","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jong Keun","family":"Seon","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eun Kyoo","family":"Song","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2308","reference":[{"key":"e_1_3_1_2_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-198769030-00005"},{"key":"e_1_3_1_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00167-002-0334-7"},{"key":"e_1_3_1_4_2","doi-asserted-by":"publisher","DOI":"10.2106\/00004623-200303000-00011"},{"key":"e_1_3_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocl.2005.05.009"},{"key":"e_1_3_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.knee.2005.08.002"},{"key":"e_1_3_1_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/01.btk.0000164755.04528.da"},{"key":"e_1_3_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.arthro.2004.01.024"},{"key":"e_1_3_1_9_2","doi-asserted-by":"publisher","DOI":"10.1097\/JSA.0b013e3180303592"},{"key":"e_1_3_1_10_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546503258880"},{"key":"e_1_3_1_11_2","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506287297"},{"key":"e_1_3_1_12_2","doi-asserted-by":"publisher","DOI":"10.1007\/s00402-005-0038-9"},{"key":"e_1_3_1_13_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0030-1248032"},{"key":"e_1_3_1_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.injury.2004.05.013"},{"issue":"10","key":"e_1_3_1_15_2","first-page":"s130","article-title":"High tibial osteotomy: does navigation improve results?","volume":"29","author":"Maurer F","year":"2006","unstructured":"Maurer F, Wassmer G.
