Natural-Knee® Modular Cemented Baseplate Designed to meet the challenges of a cemented procedure

Natural-Knee® Modular Cemented Baseplate The Natural-Knee Modular Cemented Baseplate is made from cast cobalt chrome and is designed to optimally address the issues and challenges of a cemented baseplate procedure. The baseplate complements the existing family of baseplates and can be used with the primary, revision and CRK (constrained) femoral components as well as all Natural-Knee tibial insert congurations. A/P and M/L postoperative radiographs Design Rationale • Keel and boss surface nish affords bone ongrowth and cement adhesion • Asymmetric design matches the proximal tibia and avoids...

• Outer periphery surface nish of the tibial tray prevents cement adhesion, thus reducing cleanup time • Inside surface of the tibial tray has a smooth nish to reduce the potential for backside wear • Reduced boss diameter and thin keel ns are bone-conserving The radius of the keel ns prevents stress risers in the cement and also expands out to the areas of dense bone for optimal anti-rotation • Baseplate, distal plug and stem/ plug screw are made of cobalt chrome to reduce the potential problems associated with combining dissimilar metals • Stem/plug screw is “self-captured” to prevent disassembly...
