Effects of eccentric loading in TKR: an explicit FE study

Effects of eccentric loading in TKR: an explicit FE study
The stress distribution within the polyethylene component of a TKR is ultimately dependent on the kinematics of the replaced knee. In turn, the kinematics are dependent on the design of the implant, the relative alignment of the components and tensions of the surrounding soft tissues. Clinical fluoroscopy studies have shown that unicondylar loading occurs in up to 90% of replaced knees [1]. However, the impact on the polyethylene stresses is unknown. The aim of this study was to examine the influence of unicondylar loading during a gait cycle on the predicted kinematics and stresses generated by a commercially available TKR.

Abstract

The stress distribution within the polyethylene component of a TKR is ultimately dependent on the kinematics of the replaced knee. In turn, the kinematics are dependent on the design of the implant, the relative alignment of the components and tensions of the surrounding soft tissues. Clinical fluoroscopy studies have shown that unicondylar loading occurs in up to 90% of replaced knees [1]. However, the impact on the polyethylene stresses is unknown. The aim of this study was to examine the influence of unicondylar loading during a gait cycle on the predicted kinematics and stresses generated by a commercially available TKR.
