Primary stability of tibial plateaus under dynamic compression-shear loading in human tibiae - Influence of keel length, cementation area and tibial stem

From our observations, we conclude that there is no significant difference between a 40 mm and a 28 mm tibial keel & stem length and also between a surface and a full cementation in the effect on the primary stability of a posterior stabilised tibial plateau, in terms of failure load, migration characteristics and cement layer thickness including the penetration into the trabecular bone.
