Design outcomes

Primary

Measure	Time frame
Biomechanical limb alignment, femoral and tibial component position	—

Secondary

Measure	Time frame
All patients are operated with PSMI. The operating surgeon reviewed all the pre operative digital plans and had the ability to change the default settings provided from the software. Per operative changes of the approved size of the planned femoral and tibial component are noted if approved pre operative planning changed. Mean operation time (incision to closure in minutes) and blood loss (in ml) will be obtained from the operative record.	—
