Functional Positioning for Knee Planning

摘要

Articular features in a joint may be characterized by fitting equations to a series of control points representative of one or more articular features on a bone of the joint. The equations may be fit to the control points by use of a regression, such as a least squares regression. The fit equations may be used to create best fit curves for the articular features. Disease states may be accounted for in deriving the best fit curves from the fit equations. An articular implant may be constructed or selected to match the best fit curves.
