INTRODUCTION The present teachings provide various methods of pre-operative planning for orthopedic procedures customized for particular patients.
SUMMARY The present teachings provide a method for pre-operative orthopedic planning includes obtaining only a high-resolution knee-joint scan of a patient, determining hip rotation center and ankle rotation center from anthropometric data based on personal data of the patient, and determining a mechanical axis of the knee joint based on the anthropometric data. The method also includes preparing at least a two-dimensional image model of the knee joint using the knee-joint scan and the determined mechanical axis, and preparing a pre-operative surgical plan based on the image model of the knee joint.
In one embodiment, illustrated in reference to FIGS. 16-18, a high-resolution image of the knee joint only is used together with anthropometric data to prepare a three-dimensional model of the knee joint. Anthropometric data are publicly available from many sources and can include, among other things, lengths for body segments, density, mass and inertial properties, and centers of mass and axes of rotation. See, for example, David Winter, Biomechanics and Motor Control of Human Movement, 4th Edition, Chapter 4, Anthropometry, 2009, John Wiley & Sons, Inc. FIG. 4.1 of Winter's book provides, for example, various body segment lengths expressed as a fractions of body height. The Department of Defense maintains a collection of anthropometry resources. See for example the website of the Defense Technical Information Center (DTIC) at �dtic.mil/dticasd/anthro.html#data�.
