Design outcomes

Primary

Measure	Time frame
"Pain," "gait function," "mobility," "stability," and "alignment" from the "Japanese Society of Foot Surgery's Rearfoot Function Evaluation Scale" are measured for clinical function evaluation, "pain," "physical function," "social function," "shoes," and "overall sense of health" from "Safe-Q" for patient-oriented evaluation, and "talar tilt angle," "Anterior Drawer %," and "joint dissection distance" from stress radiographs for the radiologic assessment before surgery and one year after surgery.	—
