Design outcomes

Primary

Measure	Time frame
Number of days after surgery until the patient meets the criteria for discharge from hospital	—

Secondary

Measure	Time frame
Correlation between the number of postoperative days until the achievement of discharge criteria and the patient-reported questionnaire at 12 months post-surgery (stratified analysis by number of days achieved: stratified analysis of the KOOS, KOOS Jr, and EQ-5D-5L patient-reported questionnaires at 3, 6, and 12 months post-surgery) Correlation between the number of times the patient education app is used and improvement in walking ability up to 12 months post-surgery Correlation between the type of artificial knee joint, surgical information, knee joint range of motion before and after surgery, rehabilitation information (number of times/number of units) and the patient-based questionnaire.	—
