Abstract: The present disclosure is related to computing devices, systems, and methods for a new task-engine system that connects to a variety of task-interaction providers, enabling a user to use any one of multiple task-interaction providers to create and complete tasks within a workflow. That is, the connection to a variety of task-interaction providers allows a user to interact with the workflow through any of the task-interaction providers and create and/or complete any number of tasks in the workflow. The task-engine system may also update the creation and/or completion of a workflow task in all other task-interaction providers, such that all users may be aware of, or notified of, the current state of the workflow through any of the task-interaction providers.

Abstract: A system for preparing a bone for implantation of a component of an orthopedic implant device. The system includes a forming tool having a sleeve member that is selectively received within a handle member. The sleeve member has a guide slot that is sized to receive axial passage of at least a portion of a guide. The guide slot and/or sleeve member may be positioned and/or configured to facilitate at least linear and/or rotational displacement of the forming tool about, or relative to, the guide, and thereby provide a degree of freedom in the location at which the forming tool may form a shape or opening in the bone relative to one or more reference axes. The handle member may include a connection member that is structured to be operably coupled to a bone preparation device that is structured to facilitate the displacement of bone material.

Abstract: Disclosed herein is a patella clamp configured to grip a patient's patella. The patella clamp includes a clamping assembly, a ratchet arm assembly, and a handle assembly. The clamping assembly includes first and second patella grip portions mounted in opposing relationship. In use, actuation of the handle assembly moves the second patella grip portion towards the first patella grip portion to clamp the patient's patella. The handle assembly is configured to be moveably adjustable (e.g., rotatable) relative to the clamping assembly. For example, each of the first and second patella grip portions are coupled to mating features mounted on the ratchet arm assembly. Decoupling of the mating features allows the first and second patella grip portions to rotate about the longitudinal axis of the ratchet arm assembly. Thus arranged, the patella clamp is configured to enable the surgeon to reposition the handle assembly to provide increased visibility, etc.

Abstract: Patient specific implant technology, in which an outline representation of a portion of an outer surface of a periphery of a bone volume is determined and the outline representation is used in operations related to implant matching. In addition, an instrument may be made to match a perimeter shape of a Patient Specific Knee Implant with features for locating holes in a distal femur such that posts or lugs in a femoral implant locate the femoral implant centered medial-laterally within an acceptable degree of precision to prevent overhang of either the side of the femoral implant over the perimeter of the distal femur bone resections. Further, a two-dimensional outline representation may be segmented into segments that correspond to resection cuts used in fitting an implant on a portion of a bone and operations related to implant matching may be performed based on the segments.

Abstract: Anatomically shaped augments that are configured for implantation in a bone and which have one or more reliefs. A distal end of an outer portion of the augment can have a shape that is configured to generally conform to the shape of a metaphyseal-diaphyseal junction of an intramedullary canal of a bone. A proximal end of the outer portion can have a shape that is configured to generally conform to a shape of the metaphyseal region of the intramedullary canal. The reliefs can be configured to reduce a size of the augment and enhance the degree of freedom in the implant positioning and/or sizing of the augment. Further, such reliefs may contour the augment so as to prevent cortical bone contact and/or prevent contact with the implant device that may be associated with misalignment between an intramedullary canal and metaphyseal or diaphyseal regions of the bone.

Abstract: A computer-implemented method of improving a patello-femoral response is described. A computing system characterizes an anterior geometry of a patella and determines a position of a posterior apex of the patella in relation to one or more features of the anterior geometry of the patella. The computing system further receives location information related to the patella as a knee joint is moved through a range of motion. The computing system provides one or more recommendations to improve a patello-femoral response.
