Abstract

Using the guiding assumption that the principal direction of motion about the knee is about the true flexion axis, we have developed an objective means to accurately detect and correct for errors in the estimated knee axes of rotation. The method has been shown to be robust against a large magnitude of marker misplacement. This method may improve clinical assessments of gait, specifically in cases of pathologic tibial rotation.
