Opening gap width influences distal tibial rotation below the osteotomy site following open wedge high tibial osteotomy.

ABSTRACT: PURPOSE:Although rotation of the distal portion of the tibia below the osteotomy site is considered an inevitable change in the axial plane in open wedge high tibial osteotomy (HTO), several studies on this issue have shown contradictory results. The purpose of this study was, therefore, to determine the direction and amount of distal tibial rotation following open wedge HTO using a three-dimensional reconstructed model. METHODS:This study involved 41 patients (42 knees) undergoing open wedge HTO for primary medial osteoarthritis. Distal tibial rotation was measured on the overlaid tibial plateau of a preoperative and postoperative 3-dimensional reconstructed model based on computed tomography. RESULTS:The mean distal tibial external rotation was 2.7° ± 2.3° (range, -0.9° to 9.9°), and the
