Primary Outcome Measures

Name	Time	Method
The primary objective of this study is to investigate the respective revision rates and the respective implant survival after a change operation using the implant systems cones, sleeves and wedges.

Secondary Outcome Measures

Name	Time	Method
As a secondary objective, patient satisfaction and the subjective function of the joint will be investigated by means of questionnaires within the framework of a patient survey. On the other hand, the radiological images already taken pre- and postoperatively as well as follow-up images will be analyzed with regard to common radiological criteria of knee endoprosthetics (loosening according to Knee Society Roentgenographic Evaluation and Scoring System - KSRESS, joint and implant position pre- and postoperatively with common axial angles).
