title: [Analysis of kinematic parameters of normal-paced gait in subject after posterior cruciate retention and substitution total knee replacement--leading article].
abstract: The main goal of this study was to estimate the variability of gait parameters (angular changes) in patients after cruciate-retaining and cruciate-substituting total knee arthroplasties. Angular changes of the knee joint in three planes were taken into consideration. The three-dimensional analysis of locomotion pattern was carried out on 18 patients aged 60-74, using the Vicon system. 8 patients were after posterior cruciate-retaining (CR) total knee arthroplasty and 10 after posterior-stabilized (PS) arthroplasty. The control group consisted of 30 healthy subjects 50-70 years old. The results showed, that CR patients walked on flexed knees and the varus alignment in stance phase was observed. Increased internal rotation was also visible. The movement analysis of PS knee joints was similar to CR group but the angular changes in frontal and transversal planes were more increased compared to the norm.
