Femoral condyle motion of the knee is generally reported using a morphological trans-
epicondyle axis (TEA) or geometric center axis (GCA) in the investigation of the knee …

Purpose The purpose of this study was to identify factors related to the external rotation of
the femur during knee flexion. Methods Three-dimensional (3D) digital models of the femur …

While there is general agreement on the transverse plane knee joint motion for loaded
flexion activities, its kinematics during functional movements such as level walking are …

Objective: Osteoarthritis (OA) is a multifactorial musculoskeletal disorder affecting mostly
weight-bearing joints. Chondrocyte response to load is modulated by inflammatory …

This study aimed to compare the in-vivo kinematics and articular contact status between
medial-pivot total knee arthroplasty (MP-TKA) and posterior stabilized (PS) TKA during …

Axial tibial rotation is a characteristic motion of the knee, but how it occurs with knee flexion
is controversial. We investigated the mechanisms of tibial rotations by analyzing in vivo …

Introduction The impact of rotational angle between the femoral and tibial components is
often overlooked in the 2D evaluation of varus/valgus stability after TKA with anterior …

This study aimed to develop and validate a novel flexion axis concept by calculating the
points on femoral condyles that could maintain constant heights during knee flexion. Twenty …

Abstract Knowledge of anterior–posterior (AP) movement of the femoral condyles on the
tibia in healthy knees serves to assess whether an artificial knee restores natural movement …

Total knee arthroplasty (TKA) is a standard surgical procedure commonly used for the
treatment of end-stage osteoarthritis and rheumatoid arthritis. However, a substantial …
