Gait analysis of patients following totalcondylar knee arthroplasty

Abstract

The aim of this study was to evaluate total knee arthroplasty success, throw gait analysis of patients who were underwent a surgery according to objective indicators. Material and methods: Fourteen patients were participated in our study who suffered from a certain type of gonarthrosis. Data were gathered(collected) using a commercial OptiTrack system for motion recording using six infrared cameras. Markers were placed on patients’ lower extremities, on previously determined anatomical regions. After recording the data were processed using computing environment MATLAB. Results: Observing our lab results we noticed a significant reduction in range of motion (ROM) of arthritic knees in relation to the healthy knees. ROM reduction is primarily related to flexion and extension, as well as to medial and lateral translation. Following the TKA, ROM increases, and these values get close to the values that were measured in a healthy knee. The results were presented using graphs for a healthy, damaged and operated knee, and values of corresponding parameters were given using tables. Conclusion: Using our results we showed that there is a big difference in the movement pattern of patients with gonarthrosis before and after the TKA and that that difference can be determined successfully quickly using Optitrack system.
