Assessment of pre- and post-operative gait dynamics in total knee arthroplasty by a wearable capture system.

Background: Walking function reconstruction is suboptimal after total knee arthroplasty. However, a comprehensive investigation of kinematic and kinetic parameters before and after total knee arthroplasty is lacking. This study aimed to quantitatively compare the differences in gait parameters before and after total knee arthroplasty with those of healthy control group.
