The JPEG files of the radiographs were imported to landmark\u2010based software. Deformity analysis and planning of correction were performed by 1 experienced and 2 unexperienced observers. Osteotomy planning was aimed at correction to the predefined mechanical tibiofemoral angle of 3\u00b0 valgus leg alignment. The interrater reliability of measurements was assessed using intraclass correlation coefficients (ICCs) and the confidence interval.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The ICC of PreOPlan<jats:sup>\u00ae<\/jats:sup> was from 0.841 (mechanical lateral distal femur angle) to 0.993 (wedge\u2010angle) and from 0.896 (joint line convergence angle) to 0.995 (mechanical tibiofemoral angle) of mediCAD<jats:sup>\u00ae<\/jats:sup>. The ICC of height of wedge\u2010base was 0.979 with PreOPlan<jats:sup>\u00ae<\/jats:sup> and 0.969 with mediCAD<jats:sup>\u00ae<\/jats:sup>. Comparing PreOPlan<jats:sup>\u00ae<\/jats:sup> and mediCAD<jats:sup>\u00ae<\/jats:sup>, the ICC of the height of wedge\u2010base of the observers was 0.966, 0.956 and 0.969, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The results show a high interrater reliability of digital planning software. Experience of the observer had no influence on results. Furthermore, a high interrater reliability and correlation of digital planning specific parameters was found. Surgeons need to master limb geometry measurements and osteotomy planning on digital radiographs as digital planning reports are used for intercolleagual correspondence, teaching purposes and as medicolegal documents. The digital planning software tested agrees with the actual demands and could be recommended for deformity analysis and planning of osteotomies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Level of evidence<\/jats:title><jats:p>Diagnostic studies, Level I.<\/jats:p><\/jats:sec>","DOI":"10.1007\/s00167-012-2114-3","type":"journal-article","created":{"date-parts":[[2012,7,6]],"date-time":"2012-07-06T02:37:41Z","timestamp":1341542261000},"page":"189-196","source":"Crossref","is-referenced-by-count":113,"title":["Digital planning of high tibial osteotomy.
