The purpose of the study is to analyse the clinical and radiological results of a postero-stabilized TKA by using a mobile bearing versus fixed. Only patients with medial femorotibial arthritis will be included. The consequences on the patellofemoral joint will be thoroughly analysed on skyline view.
