Abstract
A biomechanical gait analysis of patients before and after total knee replacement is used as an objective means to evaluate the functional effect of such a surgical procedure. Two types of knee prostheses are selected for this evaluation. The experimental setup for the gait analysis includes a specially designed walkway with overhanging movable data tracks, a dynamic force plate flush mounted in the middle of the walkway, knee electrogoniometers, foot switches, and a knee muscle torque tester. Data collection and reduction are automated. The gait variables are subjected to statistical analysis, harmonic spectrum analysis, and parametric phase-plot evaluation. The preliminary results have shown that the biomechanical evaluation method is reliable and effective in assessing the functional improvements brought about by this reconstructive surgery.
