Design outcomes

Primary

Measure	Time frame
Differences between navigated and conventional operated knees regarding clinical outcome and patient satisfaction. The following parameters will be evaluated: active and passive range of motion as well as anterior, medial, and lateral knee stability. All clinical tests will be done in a side-to-side comparison manner between the operated and non-operated knee. Knee range of motion will be assessed utilizing a goniometer. Stability assessment will include the Lachmann-test for anterior stability as well as valgus/varus tests for medial/lateral knee stability. Additionally, knee function will be objectively assessed utilizing the Timed up and Go-Test and subjectively with the Oxford Knee Score and Knee Osteoarthritis Outcome Score - Physical Function Short Form. Patient satisfaction will be assessed with the EQ-5D-3L.	—
