Comparison of the Radiologic Results of Total Knee Arthroplasty using Electromagnetic Navigation with the Conventional Technique

Abstract

Purpose:We wanted to examine the accuracy of the lower limb alignment and implant positioning that was obtained with using the electromagnetic (EM) navigation technique. Conclusion:The use of EM navigation technique in TKA does not always guarantee the precise alignment of the mechanical axis in all planes, as compared to using the conventional technique. Yet it is useful for obtaining better coronal alignment of the femoral component.

The Position of Proximal Reference Point of Tibia Plateau for Correct Tibial Osteotomy in Total Knee Replacement: Prospective Randomized and 6 Years Follow-up Study

“…Favorable results were documented in the studies carried out by Bellemans et al20) using Robodoc and Mizu-Uchi et al21) using a computed tomographybased navigation system. However, Won et al22) reported that the incidence of outliers was 6% in their study of TKA using an electromagnetic navigation. Bae et al23) suggested the need to be cautious with navigation-assisted TKA in knees with varus deformity based on their observation that the postoperative mechanical axis was more significantly varus in patients with 20°-30° of preoperative varus deformity than those with 10°-20° of preoperative varus deformity.…”
