Outcomes

Primary Outcomes

Knee Society Score, KSS

Time Frame: 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery

Use of Knee Society Score scales for assessment. Including pain, mobility, stability, the patient\'s ability to walk, up and down the stairs, etc. on the assessment, 85-100 is excellent, 70-84 is good, 60-69 is pass, less than 60 is poor

Secondary Outcomes

WOMAC(Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery)
Stride length(Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery)
Stride frequency(Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery)
Percentage of stance phase(Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery)
