Primary Outcome Measures

Name	Time	Method
The primary objective of this study is to investigate the revision rate and implant survival after UKA-to-TKA replacement surgery over the long term. In addition, the revision rate and implant survival for UKA implants can be determined in the same step and, if possible, different types of sled prostheses can be compared.

Secondary Outcome Measures

Name	Time	Method
As secondary objectives, 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).
