Fig. 4From: Comparative retrieval analysis of a novel anatomic tibial tray backside: alterations in tibial component design and surface coating can increase cement adhesions and surface roughnessBox plots showing comparison of area covered by cement in the two designs analyzed. The difference between the novel anatomic knee system (Persona®) and the predecessor knee system (NexGen®) was significant (p < 0.001). The partitioning of NexGen® according to time to revision shows that time to revision did not influence the amount of cement adhesions significantlyBack to article page
