Knee Society Score, KSS
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
Time frame: 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery
WOMAC
The Western Ontario and McMaster Universities Arthritis Index (WOMAC) is widely used in the evaluation of Hip and Knee Osteoarthritis. It is a composite outcome measure consisting of multiple measures: pain, stiffness and physical function. The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function. Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.
Time frame: Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery
Stride length
The step length data were collected using a gait analysis instrument to analyze whether there was a difference between the right and left sides.
Time frame: Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery
Stride frequency
The step frequency data were collected using an instrument to analyze whether there were any differences.
Time frame: Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery
Percentage of stance phase
The stance phase is the time during which the lower limbs are in contact with the ground and are subjected to gravity, and accounts for 60% of the walking cycle. In walking disorders, the prolongation of the stance phase is often associated with impaired walking.
Time frame: Preoperative, 6 weeks, 3 months, 6 months, 12 months, 24 months after surgery
