Measurement of anterior-posterior knee laxity: a comparison of three techniques.


Several non-invasive techniques have been developed to assess anterior-posterior (A-P) laxity of the knee, however, their accuracy remains unclear. Roentgen Stereophotogrammetry Analysis (RSA) is a three-dimensional motion analysis method that has been shown to be an accurate tool for evaluating joint kinematics. Thus. RSA provides a means that can be used… (More)
