Design outcomes

Primary

Measure	Time frame
Aims of the non-invasive study are the acquisition of data on leg axes and joint surfaces via dimensioning of existing radiographs and via two scores (Oxford Knee Score and WOMAC) on postoperative function, mobility and quality of life at least 1 year to maximum 3 years after implantation.	—

Secondary

Measure	Time frame
The aim is to find out which values in terms of stability, function, mobility and quality of life are to be recorded for varus deformities as opposed to valgus deformities, or whether a significant difference can be expected from a degree of severity with regard to the leg axis.	—
