摘要： According to one example, a tibial prosthesis that can include a tibial bearing component, tibial baseplate, an insert and a fastener. The tibial bearing component can have medial and lateral proximal articular surfaces and an opposing distal surface. The tibial bearing component can define at least one recess therein with the recess having an opening at a periphery of the tibial bearing component. The tibial baseplate can be coupled to the tibial bearing component on the proximal surface thereof and having a distal surface configured to be disposed on a resected proximal surface of a tibia. The insert can be configured to be disposed within the recess and can engage the tibial baseplate and the tibial bearing component. The fastener can be insertable into the tibial bearing component and can be configured to retain the insert to the tibial baseplate.

摘要： A tibial prosthesis has a bearing component configured for an anterior-medial insertion, which advantageously avoids the extensor mechanism of the knee. A tibial tray may include a banana-shaped boss that corresponds to a notch formed in the bearing component. After the bearing component is inserted along the anterior-medial path, the boss is received within the notch by rotating the bearing component with respect to the tibial tray. This rotation seat the bearing component upon the tibial tray in the manner of a fixed-bearing prosthesis. Alternatively, the boss and notch may define angled central axes which allow straight anterior-medial insertion of the bearing component and locking engagement to the tibial tray.

摘要： A trialing assembly for use during knee replacement procedures to determine size and position of a tibial plate implant as well as the size and thickness of the articular surface prior to implantation of the implant. The trialing assembly includes a broaching plate having a tibia engaging bottom surface adapted for placement atop a tibia and an opposite top surface, the bottom and top surfaces extending between an anterior edge and a posterior edge of the broaching plate. The broaching plate includes an anterior rail and a posterior rail protruding superiorly from the top surface and extending along the anterior and posterior edges, respectively. A trialing plate is configured to removably fit atop the broaching plate between the anterior and posterior rails. The trialing plate includes an engagement member extending from a superior surface of the trialing plate and adapted to engage with an articular surface provisional.

摘要： A tibial prosthesis, and, particularly, a fixed bearing tibial prosthesis has a two-pronged securement mechanism. The securement mechanism may or may not be angled. Advantageously, the securement mechanism, working alone or in cooperation with other securement features, minimizes micromotion between the tibial tray and tibial bearing component.

摘要： A mobile bearing knee prosthesis apparatus includes a tibial plate. The tibial plate includes a medial lobe and a lateral lobe conjoined in a dividing plane. The apparatus further includes a tibio-femoral insert and a stud-like protuberance extending from the tibial plate into the tibio-femoral insert. The stud-like protuberance includes a protuberance sidewall positioned in the tibio-femoral insert. The protuberance sidewall is bisected by the dividing plane and includes a pair of opposing eccentric convex arcuate portions, and the tibio-femoral insert is moveable relative to the tibial plate about an axis medially disposed from the dividing plane. A mobile bearing knee prosthesis apparatus includes a tibial plate and a tibio-femoral insert coupled to the tibial plate. The tibio-femoral insert includes a generally posteriorly positioned chamfered superior surface and defines a generally posteriorly positioned generally U-shaped space bounded at least in part by the chamfered surface.
