영문 초록

Purpose This study is to compare the radiologic results of limb alignment after total knee replacement(TKR) using CT-based surgical planning system(Robodoc system) and conventional system. Materials and methods From July 2004 to December 2006, We selected that 25cases were operated TKR using CT-based surgical planning(group A) and conventional method(group B). We measured mechanical femoro-tibial angle, femoral and tibial component angle in coronal. and sagittal plane using the weight bearing whole leg radiograph taken 1-month postoperatively. Results Mechanical femoro-tibial angle was 0.73° of valgus in CT-based surgical planning group(group A) and 2.53° of valgus in conventional group(group B) on average. Mechanical femoro-tibial angle was significantly more accurate in group A than group B. Femoral and tibial component angle in the coronal plane was 91.09° and 89.49° in group A, 91.70° and 89.52° in group B on average. Femoral and tibial component angle in the sagittal plane was 89.12° and 88.29° in group A, 88.19° and 88.49° in group B on average. There were no signigicant differences between two groups in the femoral and tibial component angle in coronal and sagittal plane. Conclusion According to the results CT-based surgical planning system(Robodoc system) helped increase alignment accuracy of the lower extremity in total knee replacement(TKR).
