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.

Tibial prosthesis with tibial bearing component securing feature

An orthopaedic knee prosthesis includes a tibial bearing component with articular features which operate to protect adjacent soft tissues of the natural knee, promote and/or accommodate desired articulation with an abutting femoral component, and facilitate expedient and effective implantation by a surgeon.

Tibial bearing component for a knee prosthesis with improved articular characteristics

According to one example, a system for a knee arthroplasty that can optionally comprise: a femoral prosthesis having a joint facing surface and an opposing bone facing surface, wherein the femoral prosthesis has one or more attachment elements at or adjacent the bone facing surface; and one or more features selectively attachable with the femoral prosthesis via the one or more attachment elements, wherein the one or more features comprise one of a box, a stem, or a combination of the box and the stem.

Knee prosthesis system and method

According to one example, a tibial replacement assembly for a knee arthroplasty can be configured to couple to a resected proximal surface of a tibia of a human knee. The tibial replacement assembly can include a tibial tray and a first spike. The tibial tray can include a proximal surface and a distal surface opposing the proximal surface. The distal surface can be configured to be disposed on a resected proximal surface of a tibia. The first spike can be removably secured to the tibial tray and can extend generally distally away from the distal surface. The first spike can be configured to extend beneath the resected proximal surface of the tibia.

Tibial tray with removable spikes

A set of distal femoral knee prostheses which are designed to be more narrow in medial/lateral dimensions with increasing anterior/posterior size than existing prostheses to more closely correspond to the physical anatomy of female patients. The prostheses are designed to have a substantially trapezoidal shape or profile when viewed distally which features a more pronounced narrowing of the medial/lateral dimensions beginning at the posterior end of the prostheses and progressing anteriorly to the anterior end of the prostheses. Additionally, the prostheses each include a reduced profile patellar sulcus and reduced profile anterior condyles to more closely conform to the anatomy of a resected femur, and also include sulcus tracking optimized to conform to female anatomy.

Distal femoral knee prostheses

A provisional femoral component, in one embodiment, including at least one first visual indicator and at least one second visual indicator, the first and second visual indicators providing indicating means for simultaneously visually representing a first profile of a first femoral prosthesis and a second profile of a second femoral prosthesis. In another embodiment, a provisional femoral component including a patellofemoral flange having two sulci and a central ridge between the two sulci. In this manner, the provisional femoral component can be positioned on a resected distal femur surface of both a right and left knee joint.

Femoral prosthesis system

An orthopaedic knee prosthesis includes a tibial bearing component with surface features which operate to protect adjacent soft tissues of the natural knee throughout a wide range of flexion. More particularly, the tibial bearing component provides an anterior relief space disposed between the dished lateral and medial articular compartments, in which the relief space is convex as viewed from a sagittal perspective across the medial/lateral extent of the relief space.

The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.
