Abstract

A tibial implant for knee arthroplasty includes a tibial plate, a tibial keel, and at least one anchoring projection. The tibial plate is sized and shaped for placement on a proximal end of a tibia of a patient. The tibial plate includes opposite proximal and distal surfaces with the distal surface configured to engage the end of the tibia. The tibial keel extends distally from the distal surface of the tibial plate and is configured to be inserted into the proximal end of the tibia. The anchoring projection extends distally from the distal surface of the tibial plate and is configured to be inserted into the proximal end of the tibia.
