Inclusion Criteria

Male or female patients aged = 18 years.
- Primary gonarthrosis with indication for implantation of a KTEP

Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The primary endpoint is the Oxford Knee Score (OKS) of the uncemented implant after 2 years, the non-inferiority of which will be shown compared to an already clinically established cemented procedure.

Secondary Outcome Measures

Name	Time	Method
- Recording of surgery-specific parameters (incision-suture time, blood loss, postoperative transfusion requirements)<br>- Recording of early complications, revision rate, implant survival<br>- Examination of the native radiological images during the course of the operation for early signs of loosening (radio lucent lines) and recording of the positioning and position of the prostheses in a group comparison.
