Purpose: When downsizing the femoral component to prevent mediolateral overhang, notching of the anterior femoral cortex may occur, which could be solved by flexing the femoral component. In this study, we investigated the effect of flexion of the femoral component on patellar tendon moment arm, patellofemoral forces and kinematics in posterior-re...

Purpose: In total knee arthroplasty (TKA), the posterior tibial slope is not always reconstructed correctly, and the knee ligaments may become too tight in flexion. To release a tight flexion gap, surgeons can increase the posterior tibial slope using two surgical resection techniques: the anterior tibial cortex (ACR) or the centre of tibial plate...

INTRODUCTION: Tibial slope can affect the outcomes of Total Knee Arthroplasty (TKA). More posterior slope potentially helps releasing a too tight flexion gap and it is generally associated with a wider range of post-operative knee flexion. However, the mechanism by which tibial slope affects the function of TKA during dynamic activities of daily li...

INTRODUCTION: Increasing the amount of posterior tibial slope in Total Knee Arthroplasty (TKA) was suggested as a manner to release a tight flexion gap. However, an excessive tibial slope could jeopardize the knee stability in flexion. The effects of varying tibial slope on the amount of laxity of the knee joint remain unclear. The aim of this stud...

INTRODUCTION: One of the main goals in Total Knee Arthroplasty (TKA) is to restore natural knee kinematics and physiological loads in tibiofemoral (TF) and patellofemoral (PF) joint. The extent to which this is achieved may differ substantially, depending on many factors. Adding extra flexion of the femoral component (FFC) in the sagittal plane dur...
