Abstract: The exemplary embodiments of the present disclosure are described and illustrated below to encompass methods and devices for designing patient specific prosthetic cutting jigs and, more specifically, to devices and methods for segmenting bone of the knee and the resulting cutting guides themselves. Moreover, the present disclosure relates to systems and methods for manufacturing customized surgical devices, more specifically, the present disclosure relates to automated systems and methods of arthroplasty cutting guides, systems and methods for image segmentation in generating computer models of knee joint.

Abstract: A method of designing a prosthetic implant. Exemplary methods may include developing a three-dimensional model of an anatomic feature from one or more two-dimensional images. The three-dimensional model may include a plurality of radii of curvature representing the shape of respective portions of a contact surface. In some exemplary embodiments, three-dimensional models associated with a large number members of a population may be utilized to create templates for prosthetic implants. A three-dimensional model of an anatomic feature of a patient may be compared to the available templates, and a suitable template may be tested by virtually implanting the template on the three-dimensional model of the patient's anatomical feature. In some embodiments, a patient's three-dimensional model for which a suitable pre-made template is not available may be used to customize a pre-made template to design a suitable implant.

Abstract: A method for anatomical analysis and joint implant design. Embodiments provide users with the ability to anatoically analyze a single bone or a series of bones that exist in a database, evaluate surgical landmarks and axes, identify differences among specific characteristics of a given population, and modify existing implants or create new implant designs based on anatomical analyses.
