The goal of this pilot study was to develop and test an integrated method to
assess kinematics, kinetics and muscle activation of total knee prostheses during
dynamic activities, by integrating fluoroscopic measurements with force plate,
electromyography and external motion registration measurements. Subsequently,
this multi-instrumental analysis was then used to assess the relationship between
kinematics, kinetics and muscle activation and early migration of the tibial
component of total knee prostheses. This pilot study showed that it is feasible
to integrate fluoroscopic, kinematic and kinetic measurements and relate findings
to early migration data. Results showed that there might be an association
between deviant kinematics and early migration in patients with a highly
congruent mobile-bearing total knee prosthesis. Patients that showed high levels
of coactivation, diverging axial rotations of the insert and a deviant pivot
point showed increased migration and might be at higher risk for tibial component
loosening. In the future, to confirm our findings, the same integrated
measurements have to be performed in larger patient groups and different
prosthesis designs.
