Design outcomes

Primary

Measure	Time frame
Threshold difference between high- and low-satisfaction groups in contact pressure for the mediolateral surface of the femorotibial joint at 1 year after TKA	—

Secondary

Measure	Time frame
Difference at 1 year after TKA in clinical outcome (ROM, 2011 KSS Total Score) and patient satisfaction (2011 KSS Patient Satisfaction Score) between patients with lower contact pressure difference at the mediolateral surface of the femorotibial joint during surgery (stable group) and those with higher contact pressure difference (unstable group).	—
