Cementless tibial bearing

1.The keel wing design provides initial implantation stability. 2.With 5° retroversion angle，prevent the fontal cortex from collision； 3.Accurate and stable locking design reduces movement; 4. Wide range of AP/ML,provides better coverage of tibial plateau； 5. Can match with PS&CR two types of tibial insert. 6. The anatomical tibial plateau design,better coverage anf lower subsidence.
