Abstract
The purpose of this study was to evaluate changes in movement patterns during a sit-to-stand (STS) task before and after total knee replacement (TKR), the impact of the prosthesis on the kinematic parameters of sit-to-stand flexion movement and to compare biomechanical outcomes after TKR to a control group. A sample of seven healthy control subjects and five patients suffering of knee osteoarthritis (KOA) participated in three-dimensional motion analysis. Although there were significant improvements in movement 4 months after TKR, patients continued to demonstrate smaller moments on the prosthetic knee compared to non-operated and to control knees.
