Reported deviations are not only attributable to the alignment method but also to radiological errors. The purpose of this study was to evaluate the accuracy of the intramedullary alignment method in the sagittal plane using computed tomography (CT) and 3\u2010dimensional imaging software. Thirty\u2010one TKAs were performed using an intramedullary alignment method involving the insertion of a long 8\u2010mm diameter rod into the medullary canal to the distal metaphysis of the tibia. All alignment instruments were set to achieve an ideal varus\/valgus angle of 0\u00b0 in the coronal plane and a tibial slope of 0\u00b0 in the sagittal plane. The accuracy of the intramedullary alignment system was assessed by measuring the coronal tibial component angle and sagittal tibial slope angles, i.e., angles between the tibial anatomical axis and the tangent to the medial and lateral tibial plateau or the cut\u2010surface. The mean coronal tibial component angle was 88.5\u00b0 \u00b1 1.2\u00b0 and the mean tibial component slope in the sagittal plane was 1.6\u00b0 \u00b1 1.2\u00b0 without anterior slope. Our intramedullary tibial alignment method, which involves passing an 8\u2010mm diameter long rod through the tibial shaft isthmus, showed good accuracy (less than 3 degrees of variation and no anterior slope) in the sagittal plane in neutral or varus knees.<\/jats:p>","DOI":"10.1007\/s00167-010-1152-y","type":"journal-article","created":{"date-parts":[[2010,5,7]],"date-time":"2010-05-07T14:53:00Z","timestamp":1273243980000},"page":"1334-1338","source":"Crossref","is-referenced-by-count":11,"title":["The
