Summary

Femoral component rotation in total knee arthroplasty (TKA) has been considered an important factor for outcome. However, measurement of femoral component rotation is difficult to perform.

Femoral TKA component rotation can be assessed on special radiographs (Kanekasu technique), axial CT slices and 3D reconstructed CT images.

It was the hypothesis that measurements on radiographs are comparable to measurement on CT images.

Measurements of femoral TKA rotation will be measured three times by three different observers and inter- and intraobserver reliability is calculated. The absolute values of each measurement method is noted in degrees.

OTHER

Kanekasu radiographs

No interventions are performed here. All patients undergo CT and special radiographs of the knee to assess femoral TKA rotation.
