• 一般注記: Background Rotational mismatch between femoral and tibial components has been recognized as a risk factor of unsuccessful total knee arthroplasty (TKA), but a main cause of rotational mismatch is uncertain. This study aims to evaluate rotational alignment of the knee by measuring both component rotation and version of the knee in TKA. Method Fifty one TKAs (mean age 73.7 years) were included in this study. The three dimensional, weight-bearing knee alignment was measured before and after TKA. A transepicondylar axis was referenced to femoral component rotation, and an anteroposterior axis of the tibia (middle of posterior cruciate ligament attachment to medial border of patella tendon attachment) was referenced to tibial component rotation. Knee rotational angle was defined as the angle between these two axes. Result The mean preoperative knee rotation angle of 9.7° (±8.5°) internal rotation was significantly reduced to 1.8° (±7.3°) external rotation after TKA. Twenty-one of 51 knees (41 %) exhibited rotational mismatch (>10°) preoperatively, and this number was reduced to 8 knees (16 %) post-TKA. The femoral component was rotationally aligned within 5° of neutral in all knees, while rotational alignment of the tibial component showed a high degree of variability (range 20.7° internal rotation to 17.2° external rotation). Conclusion Rotational malposition of the tibial component was considered to be a main factor of rotational mismatch of the knee after TKA; 学位の種類: 博士（医学）. 報告番号: 甲第3942号. 学位記番号: 新大院博（医）甲第609号.学位授与年月日: 平成26年9月22日; Journal of Orthopaedic Science. 2014, 19(4), 571-578.; 新大院博（医）甲第609号; 元資料の権利情報 : Copyright © 2014 The Japanese Orthopaedic Association; 元資料の権利情報 : The final publication is available at Springer via http://dx.doi.org/10.1007/s00776-014-0565-8; 開始ページ : 1; 終了ページ : 20
