摘要： A tibial prosthesis that includes a baseplate (100) and a tibial keel (108). The baseplate including: a distal surface (104) sized and shaped to substantially cover a proximal resected surface of a tibia; a proximal surface (102) opposite the distal surface, the proximal surface having a lateral compartment (116) and a medial compartment (114) opposite the lateral compartment; a periphery (106) extending between the distal surface and the proximal surface; a first pocket (124) 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 (126) 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 (S1).

摘要： 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.
