Abstract: According to one example, a tibial prosthesis that optionally includes a baseplate and a tibial keel. The baseplate optionally including: a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia; a proximal surface opposite the distal surface, the proximal surface having a lateral compartment and a medial compartment opposite the lateral compartment; a periphery extending between the distal surface and the proximal surface; a first pocket formed in the baseplate and recessed from the distal surface, wherein the first pocket is configured to receive a bone cement therein; a second pocket formed in the baseplate and recessed from the first pocket, wherein the second pocket is configured to receive a portion of the bone cement. The tibial keel extending distally from the distal surface to define a longitudinal tibial keel axis.

Abstract: The techniques described herein relate to a tibial prosthesis for a knee arthroplasty optionally including a baseplate and a tibial keel. The baseplate optionally including: a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia; a proximal surface opposite the distal surface, the proximal surface having a lateral compartment and a medial compartment opposite the lateral compartment; a periphery extending between the distal surface and the proximal surface; a first layer of porous material forming at least a majority of the distal surface and extending to the periphery; and a second layer of non-porous or relatively less porous material having a plurality of reference features extending through the first layer, wherein the plurality of reference features form at least a portion of the distal surface; and a tibial keel extending distally from the distal surface to define a longitudinal tibial keel axis.

Abstract: A system that can be used in a knee replacement procedure can include a tibial cut guide and an alignment guide. The tibial cut guide can have a first guide portion coupled to and adjustable relative to a second guide portion. The first guide portion can be configured to define a sagittal cut slot and a proximal cut slot. The alignment guide configured for extramedullary mounting to the patient and configured to couple with the second guide portion of the tibial cut guide, the alignment guide having a first mechanism and a second mechanism of differing construction, the first mechanism and the second mechanism are both configured to be actuated to facilitate extension and retraction of the alignment guide to position the tibial cut guide in a desired proximal-distal location relative a tibia of a patient when the tibial cut guide and the alignment guide are assembled together.

Abstract: 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.

Abstract: An easily assembled provisional orthopaedic implant having first and second components. The first component may include a stem which can be inserted into an intramedullary canal and may be a femoral component of a knee joint prosthesis. The second component has a body and a sliding retention member. The retention member can be manually engaged with a groove on the stem of the first component to lock the two components together. The second component may form of an intercondylar box and have a projecting tab engageable with a recess on the femoral component to properly orient the two components when they are placed in registry with each other.
