Design outcomes

Primary

Measure	Time frame
Change in quadriceps muscle thickness according to the presence or absence of electrical muscle stimulation (thickness of the rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius measured by ultrasonography preoperatively and at 3 and 6 months postoperatively, and the change in muscle thickness at each time point compared between the intervention and control groups).	—

Secondary
