Background: In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment ofthe femoral component in total knee arthroplasty (TKA).Methods: There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittalfemoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cor...

INTRODUCTION Differences in the magnitude of bowing between races are well-known characteristics of the femur. Asian races have an increased magnitude of femoral bowing but most of the orthopedic implants designed for the femur do not match this exaggerated bowing. We calculated the sagittal and coronal femoral bowing in the Japanese population at different levels of the femur and addressed its...

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 landmarks of the femur, lateral epicondyle, and anterior margin of the greater trochanter were identified. The line connecting these two landmarks was defined as the "palpable sagittal axis". The mechanical axis of the fem...

BACKGROUND Precise measurement of lateral femoral bowing is important to achieve postoperative lower limb alignment. We aimed to investigate factors that affect the precision of the radiographic lateral femoral bowing (RLFB) angle using three-dimensional (3D) models and whether the angle affects surgery design. METHODS Forty femurs in total were divided into two groups based on their preopera...

In the current study, we investigated that how sagittal femoral bowing can affect the sagittal alignment of the femoral component in total knee arthroplasty (TKA). There were 25 patients underwent TKA. Long leg radiography in lateral view was performed. The sagittal femoral bowing (SFB) and component alignment in relation to the sagittal mechanical axis and distal anterior cortical line (DACL) ...

BACKGROUND The purpose of this study was to analyze femoral shaft sagittal parameters in Chinese osteoarthritis (OA) patients undergoing total knee arthroplasty (TKA) and identify whether the parameters in the coronal plane could be predictors of those in the sagittal plane. METHODS Standard long-standing anteroposterior and femoral lateral radiographs of 50 lower limbs in 50 Chinese OA patie...

BACKGROUND We retrospectively investigated the prevalence of femoral anterior notching and risk factors after total knee arthroplasty (TKA) using an image-free navigation system. METHODS We retrospectively reviewed 148 consecutive TKAs in 130 patients beginning in July 2005. Seventy knees (62 patients) underwent conventional TKA, and 78 knees (68 patients) received navigated TKA. We investiga...

PURPOSE Atypical femoral fractures (AFFs) occur in two distinct part, subtrochanter and diaphysis. The aim of this study was to investigate the relationship between the lateral femoral bowing angle and the location of AFF. MATERIALS AND METHODS This study included a total of 56 cases in 45 patients who underwent surgical treatment between January 2010 and December 2015. For the diaphyseal and...
