Problems solved by technology

[0009] Finally, traditional planning software does not allow users to simply input their alignment targets for each and have the system automatically output a transformation between implant and bone, which can be easily used by computer-assisted surgery systems

Embodiment Construction

[0023] The present invention is useful as a method and system for performing the method and system to assist a user in planning at least a portion of an arthroplasty procedure, such as a total knee arthroplasty. The systems and methods automatically align implant components and bone according to desired clinical alignment goals with minimal user input. The system and method also allow the user to adjust the position and orientation of the bone of the femur, tibia, or implant in a knee arthroplasty in a clinical direction regardless of the pre-adjusted position and orientation of the femur, tibia, or implant.

[0024] The following description of preferred embodiments of the invention in the context of TKA is not intended to construe the invention as such preferred embodiments, but rather to enable a person skilled in the art to make and use the invention. Reference is made herein to the planning of total knee arthroplasty, but it should be understood that embodiments of the pr...

Abstract

Systems and methods are provided to aid in planning at least a portion of a total knee arthroplasty procedure. The system and method automatically aligns the implant components and the bones accordingto a desired clinical alignment goal with minimum user input. The system and method further allows the user to adjust the position and orientation of the femur, tibia, or implant in a clinical direction regardless of a pre-adjusted position and orientation of the femur, tibia, or implant. The graphical user interface is provided that includes a three- dimensional (3-D) view window, a view optionswindow, a patient information window, an implant family window, a workflow-specific tasks window, and a limb and knee alignment measures window.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application Serial No. 62 / 302,770, filed March 2, 2016, which is incorporated herein by reference. technical field [0003] The present invention relates generally to computers for computer-assisted surgical planning, and more particularly, to computerized methods for intuitively planning a total knee arthroplasty procedure. Background technique [0004] Total knee arthroplasty (TKA) is a surgical treatment in which the articular surface of the knee is replaced with a prosthetic component or implant. TKA requires removal of worn or damaged cartilage and bone on the distal femur and proximal tibia. The removed cartilage and bone are then replaced with a synthetic implant, usually formed of metal or plastic, to create a new bonding surface. [0005] Computer-assisted surgical systems and patient-specific instrumentation (PSI) are gaining popularity as tools for...
