A system and related method for eliminating microbes from a metal orthopedic appliance includes a counter electrode and working electrode used for applying treatment, and a reference electrode used for monitoring safety parameters. The working electrode is the implanted appliance. Electrical current is applied between the counter electrode and the working electrode to create electrochemical current through the system and create electrochemical reactions on the surface of the working and counter electrode. The chemical species created at the working electrode provide a mechanism to disrupt and kill microbes on that surface, including bacterial biofilms commonly found on infected orthopedic implants. Circuitry connected to the electrodes keeps the applied current constant and allows the voltage between the working and counter electrode to vary. The reference electrode monitors the voltage at the working electrode in order to provide feedback to a processor as part of a feedback mechanism. The processor is programmed with software logic, preventing the voltage from drifting to ranges that correlate with metal immunity or corrosion regions by limiting or altering the applied current.

A measurement device is disclosed that includes a first component having an outer surface having one or more flexible articular surfaces, and an inner surface having a first area having protrusions defining a polygon with a plurality of vertices. A load plate can be in contact with the first area. A printed circuit board can have a central section and a first lateral section. The first lateral section can have a sensor array having a plurality of sensors. Each sensor can be positioned in alignment with a vertex of the polygon and having a load pad in contact with a lower surface of the rigid load plate. A reference sensor can be spaced from the lower surface of the load plate.

A joint prosthesis assembly includes a stem that includes a first end, a second end, and a length that extends between the first and second ends. The stem includes a cylindrical opening that extends into the second end along a portion of the length and terminates within the stem so as to form a base surface that defines an end of the cylindrical opening. The assembly also includes a joint component that has an articular side, a bone contact side, and a cylindrical boss that extends from the bone contact side. The boss is slidingly receivable within the cylindrical opening so that, when the stem and joint component are implanted, the stem is unconstrained in an axial direction and constrained by the stem in a direction transverse to the axial direction.

An orthopedic implant manufacturing method. The method includes preparing a pre-operative surgical plan for a specific patient, the surgical plan including a three-dimensional image of a patient's joint indicating at least one resection plane, communicating the surgical plan to a surgeon of the patient, and receiving approval of the surgical plan and the resection plane by the surgeon. The method also includes providing automated osteophyte/protrusion removal control for surgeon manipulation, receiving a modified three-dimensional image of a patient's joint indicating an osteophyte/protrusion removal and a recommendation for a corresponding selected orthopedic implant from the surgeon, and requesting manufacture of the selected orthopedic implant.

A computing system according to an embodiment includes at least one processor and at least one memory comprising a plurality of instructions stored thereon that, in response to execution by the at least one processor, causes the computing system to determine a plurality of implant size predictions with associated confidence levels based on one or more patient or surgical parameters, wherein each of the implant size predictions identifies a confidence level that a prospective implant of a corresponding size will fit a patient, determine whether a combined confidence level determined based on a subset of the plurality of associated confidence levels is at least a threshold value, and recommend, in response to a determination that the combined confidence level is not at least the threshold value, incorporation of at least one of an additional implant size prediction of the plurality of implant size predictions in the subset or digital templating data to improve an accuracy of an implant size estimation.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

A tibial implant may include a plurality of geometrically conformal implant subunits. The implant subunits may be configured for individual insertion within a wedge-shaped-void of the tibia. The implant subunits may further be configured for assembly in order to provide an implant substantially covering an exposed portion of cortical bone formed when performing a surgical osteotomy. In some embodiments, some or all of the plurality of subunits may be mechanically interlocked with each other. Methods and kits for insertion and assembly of implants are further described.
