ABSTRACT

There have been great advances in extending how long an artificial knee will last. The current investigation deals with one of the most important parameters in controlling the life span of artificial knee, which is the thickness of the polyethylene layer of Tibia Tray of artificial knee joint. Three different thickness of polyethylene layers (8, 9, and 10 mm) are available at hospitals assembled with similar identical tibia trays. This makes knee surgeons confused which polyethylene layer thickness to choose. The present work showed that a 10 mm layer is recommended for active patients, while the 9 mm layer is recommended for elder people.
