Patent attributes
A bicruciate retaining tibial implant baseplate includes a tibial baseplate with medial and lateral condylar portions configured to receive bearing inserts. The baseplate includes an anterior bridge connecting the medial and lateral portions. A posterior wall of the anterior bridge may be angled to provide downward force on a correspondingly angled anterior portion of the tibial eminence when the baseplate is implanted. A method of preparing the tibia for implant includes a punch tower and punch guide configured to both cut the anterior tibial eminence and provide protection to the tibial eminence during resection of the proximal tibia.
