A modular tibial implant includes a tibial baseplate having a top surface, a bottom surface, and first and second openings extending between the top and bottom surfaces, and a bone engaging element having a distal end, a proximal end, and a longitudinal axis extending between the distal and proximal ends, the proximal end of the bone engaging element having a threaded opening alignable with the first opening of the tibial baseplate and a post insertible into the second opening of the tibial baseplate. The implant include a threaded fastener insertible into the aligned first opening and threaded opening, wherein the threaded fastener is rotatable for securing the proximal end of the bone engaging element to the bottom surface of the tibial baseplate, and a cam element insertible into the second opening of the tibial baseplate for engaging the post. The cam element is rotatable for moving the baseplate relative to the bone engaging element along an axis that traverses the longitudinal axis of the bone engaging element.
