    Abstract: A computer-implemented method for updating a surgical plan for placement of a joint implant is disclosed. The surgical plan is obtained, including an implant model, an implant size, and an initial value for each of a plurality of placement parameters. At least one knee performance equation is selected from a library based on the surgical plan information, wherein each knee performance equation relates an output response associated with a post-operative influence to the plurality of placement parameters. Each output response is calculated across a range of values for each of a subset of the plurality of placement parameters. A graphical representation of the output response across each range is displayed, and input related to a selected value for each placement parameter of the subset is received. The surgical plan is updated based on the selected values. Devices and non-transitory computer readable media for carrying out the method are also disclosed.

    Abstract: The present invention relates to providing image data of adjustable anatomical planes. In order to provide a more user friendly way of images in selected viewing planes, a device (10) for providing image data of adjustable anatomical planes is provided that comprises a data input (12), a data processor (14), a user interface (16) and an output interface (18). The data input is configured to receive 3D image data of a region of interest of a subject. The data processor is configured to establish anatomical context for identifying anatomical reference locations within the 3D image data. The data processor is also configured to generate a reference coordinate system based on the identified anatomical reference locations. The data processor is also configured to define an anchor point. The data processor is further configured to compute a viewing plane as a selected anatomical imaging plane based on the anchor point and at least one plane-related parameter. The user interface is configured for entering the at least one plane-related parameter for determining the viewing plane as the selected anatomical imaging plane by the user. The output interface is configured to provide a representation of a view in the selected anatomical imaging plane.

    Abstract: A method for visualizing at least one region of a joint that deviates from a baseline anatomy includes receiving image data associated with a joint of a subject, generating a three-dimensional model of at least a portion of the joint using the image data, identifying at least one region of the joint that deviates from the baseline anatomy by comparing the three-dimensional model to a baseline model, generating a measurement of a characteristic of the joint at one or more predefined locations using the three-dimensional model and a coordinate system, and generating a three-dimensional rendering of the model that includes a visual indication of the at least one region of the three-dimensional model that deviates from the baseline so that the region is visually indicated according to degree of deviation, and a representation of the measurement of the characteristic of the joint that is positioned according to the predefined locations.
