Accurate sagittal alignment of the femoral component in total knee arthroplasty is crucial for
prosthesis longevity, improved function, and patient satisfaction. However, there is variation …

Purpose In contrast to coronal alignment, only few is known about sagittal alignment in total
knee arthroplasty (TKA). The aim of this study was to identify the flexion position of the …

Purpose Few studies exist regarding sagittal alignment describing femur morphology in
navigation-aided surgery. This study investigated the three-dimensional (3D) sagittal …

Purpose: This study aimed 1) to identify the rotational axis of the femur that provides a
balanced 90 flexion space in TKA, 2) to assess the changes in the flexion space in deep …

Successful total knee arthroplasty is dependent on the correct alignment of implanted
prostheses. Major clinical problems can be related to poor femoral component positioning …

Background Although several reference axes have been established for determining
femoral rotational alignment during total knee arthroplasty (TKA), the most accurate axis is …

Background: Several reference axes are used to establish femoral rotational alignment
during total knee arthroplasty, but debate continues with regard to which axis is most …

A total knee arthroplasty performed with navigation results in more accurate component
positioning with fewer outliers. It is not known whether image-based or image-free-systems …

Proper mechanical and rotational alignment plays an important role in achieving the
success of the total knee arthroplasty (TKA). The purpose of the present study was to …

Background There is no accepted landmark for the mechanical axis of the femoral axis in
sagittal plane in conventional total knee arthroplasty. Methods As palpable anatomic …
