Design outcomes

Primary

Measure	Time frame
The primary aim of this study is to obtain short and medium-term results (from a minimum follow-up of 1 year postoperatively) regarding implantation accuracy, implant survival and risk of revision of current implantation techniques of knee endoprostheses. By means of a one-time, postal patient survey about scores and free questions, the above points are raised. In addition, radiological recordings that have already been made in routine clinical checks are to be analyzed with regard to the nature of the prosthesis, loosening and the usual radiological alignment angle of the implant.	—
