Abstract: A method, system, and/or computer program product manages a set of software modules in a software runtime environment, where the set of software modules has one or more dynamic dependencies and one or more static dependencies. Each software module having a static dependency on another software module in a set of software modules is identified. Each subset of the set of software modules that is interdependent with another subset due to static dependencies between subsets is identified. In response to a change in state of a module in an identified subset, the change in state is applied to all modules in the identified subset.

Abstract: A patient-matched cutting block including a surface or point contact features adapted to at least partially conform to or reference a patient specific anatomy. The cutting block having guide slots configured for guiding the movement of cutting tools relative to the patient specific anatomy or features configured to mate to and guide standard cutting guides relative to patient specific anatomy in order to form plateau and eminence resections of the patient specific anatomy.

Abstract: Systems, methods and devices for tensioning posterior crucial ligaments during cruciate or bi-cruciate ligament-sparing arthroplasty. Non-limiting examples of such systems may include at least one series of tibial inserts of equal size; the at least one series of tibial inserts having at least one set of tibial inserts of equal thickness. The at least one set of tibial inserts of equal thickness may include at least two tibial inserts having different geometries in a posterior portion, the different geometries being configured to change the tension in the posterior cruciate ligament (PCL). The different geometries in the posterior portions of the tibial inserts are configured so as to allow the posterior cruciate ligament to be tensioned or loosened independently of the tibial insert thickness and/or size.

Abstract: A method of performing message operations includes receiving a message operation request identifying a queue, retrieving a list of the subset of partitions associated with the alias received in the request, and selecting at least one of the partitions within the retrieved subset. According to the method, the queue includes a plurality of partitions, the request identifies the queue with an alias, and the alias having a subset of the plurality of partitions associated therewith.

Abstract: Systems and methods for optimizing parameters of an orthopaedic procedure for a particular patient, including parameters relating to the anatomic and biomechanic fit of an implant or implant system implanted into the patient's joint. These systems and methods may utilize patient-specific information gathered pre-operatively in conjunction with optimization algorithms to determine an optimal implant design and an optimal position and orientation for implantation of the implant into the particular patient's joint.

Abstract: An orthopaedic implant including a base portion and first and second transverse portions extending transversely from the base portion to thereby define an inner region of the implant sized for receipt of an end portion of a bone therein. The implant further includes at least one anchor structure projecting from the base portion and sized and configured for receipt within an opening formed in the end portion of the bone. The anchor structure extends along a longitudinal axis and includes a proximal end attached to the base portion and an opposite distal end, and further includes a tapered outer surface that inwardly tapers in a proximal-to-distal direction along the longitudinal axis. In one embodiment, the anchor structure also includes one or more grooves extending into the tapered outer surface, with a flowable material positioned about at least a portion of the tapered outer surface and positioned within the grooves, and with the flowable material configured to cure to a hardened state.

Abstract: Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. Other embodiments provide improved lateral and/or medial inserts having a mesial lip that helps relieve and/or prevent impingement between the femoral component and the tibial eminence. Other embodiments provide improved femoral components having various chamfers to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.

Abstract: Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, are described herein. Methods and apparatus for preparing a distal femur for a femoral implant as well as methods and apparatus for preparing a proximal tibia for a tibial implant are described. These methods and apparatus, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures, while maintaining, if not improving on, the safety, accuracy and/or effectiveness of such procedures.

Abstract: A method for preferential reply routing, the method includes: receiving a request-reply message from a requesting application; detecting there is a preferred partition of a reply queue managed locally to an application server to which the requesting application is connected; qualifying a name of a reply queue stored in the request-reply message so that the name refers to the local partition that is managed locally to the application server; determining whether the local partition is available; wherein in the event the local partition is available: storing a reply message in the local partition; and retrieving the reply message from the local partition in response to the requesting application.

Abstract: A method of patterning a functional material (150) onto a substrate (100) comprises the steps of (a) applying a layer of protective material (130), soluble in a solvent in which the functional material is insoluble, to at least one major surface of said substrate; (b) removing areas of said layer (130) to gain access to the substrate in well-defined regions; (c) depositing the functional material (150) at least onto the substrate in the well-defined regions; and (d) removing the remaining layer of protective material from the substrate by dissolution in said solvent.
