About this study

The aim of this study is to compare knee Flexion after cruciate-retaining (CR) and cruciate-substituting (posterior stabilized - PS) Total Knee Arthroplasty (TKA).

For this purpose, flexion and extension of the knee joint are measured using a goniometer preoperatively and up to ten years after surgery In addition, the clinical outcome will be assessed and evaluated using internationally recognised and evaluated scores (Knee Society Score, Oxford Knee Score, EQ5D, UCLA Activity Score).

Patients are randomized to receive a PS or CR TKA. Patients are assessed before surgery, after 3 months, 1 year, 2 years, 5 years, 7 years and 10 years postoperatively.

Who can participate
