Further, there’s less osteolysis, better long-term survivorship than some modular designs, and better loading of the proximal tibia. What are the pros of an all poly tibia? First, you can resect less tibia for the same poly thickness and for someone who’s young that’s a big advantage. Second, many modular fixed bearing designs have been relatively disastrous and are one reason we spend so much time talking about peri-articular osteolysis. First, the best long term results with fixed bearing knees to date are those with monoblock tibial components. Trousdale: A few facts about all poly tibias or monoblock tibial components.
