Purpose Coronal alignment of the knee is defined by the hip–knee–ankle angle (HKA), the
femoral mechanical angle (FMA), the tibial mechanical angle (TMA), and the joint line …

Purpose There is a lack of knowledge about the joint line orientation of the femur and tibia in
non-osteoarthritic knees. The primary purpose of the present study was to evaluate the …

Objective This study aimed to investigate alignment based on age in normal knees and
alignment based on deformity in osteoarthritis (OA) knees using detailed radiographic …

Background Coronal alignment is considered key to the function and longevity of a TKA.
However, most studies do not consider femoral and tibial anatomical features such as lateral …

Introduction Stress fractures of the bowed femoral shaft (SBFs) may be one of the causes of
atypical femoral fractures (AFFs). The CT-based finite element method (CT/FEM) can be …

Introduction Loading stress due to individual variations in femoral morphology is thought to
be strongly associated with the pathogenesis of atypical femoral fracture (AFF). In Japan …

Forty extra-articular deformities (22 femoral and 18 tibial) in 34 patients (mean age, 63.1
years) were studied. Mean coronal extra-articular deformity was 9.3°; mean preoperative …

We analyzed the records of 29,895 high tibial osteotomies (HTOs), 12,589
unicompartmental knee arthroplasties (UKAs) and 363,386 total knee arthroplasties (TKAs) …

Background Computer navigation has improved accuracy and reduced the percentage of
alignment outliers in TKA. However, the characteristics of outliers and the risk factors for limb …

Purpose This prospective study aimed to evaluate radiographically, mechanical or hip–knee–
ankle (HKA) axis in healthy, asymptomatic, Asian (Indian and Korean) adults between 20 …
