Beside the current standard of classical mechanical alignment of total knee replacements, increased interest is being shown in anatomical alignment. However, no surgical technique is capable of controlling the stability of the joint in midflexion. The purpose of the present study was to present and evaluate a new surgical technique, which aims to reduce the need for soft-tissue release and optimize stability in midflexion.

Implantation of total knee arthroplasty using a specific operative technique (GT) serving as control.
Implantation of total knee arthroplasty using a specific operative technique (AA) being experimental.
Friedrich-Schiller University Jena, Campus Eisenberg
Eisenberg, Eisenberg, Germany
RECRUITINGMeasurement of midflexion instability (i.e. tibofemoral gap medially and laterally) in 30° and 60° of flexion
The outcome measures are given in mm.
Time frame: intraoperatively immediately before implantation of definite implants.
performance of soft tissue release (yes / no) and extend of release if done.
The surgeon documents postoeperatively if a soft tissue release was done or not and what extend a release had. The outcome measure is given in numbers (0 ... 4).
Time frame: intraoperatively
