Abstract

Although knee kinematics has been investigated widely, no standard, objective evaluation of the kinematics behaviour of the joint is used at present during surgical treatment. We propose a kinematic protocol for a manual intraoperative evaluation of the knee behaviour, with which the range of motion, the 'screw-home' mechanism and knee instabilities could be quantified. The method does not require anatomical landmarks, because it is computed from standard tests used in clinical practice and gives a decomposition of the knee movement comparable to the well known Grood and Suntay analysis [E.S. Grood, W.J. Suntay, A joint coordinate system for the clinical description of three-dimensional motions: application to the knee, J. Biomech. Eng. 105 (1983) 136-144]. We describe the protocol, report the evaluation of its numerical features and provide a comparison with Grood and Suntay method on ten porcine knees. Copyright (C) 1999 Elsevier Science Ireland Ltd.
