   Introduction
 
Ceramic-on-ceramic bearings for total hip arthroplasty were pioneered by Boutin in France during the 1970s1. The first generation of alumina ceramic experienced unacceptably high fracture rates2,3. In the 1980s and 1990s, advances in ceramic manufacturing produced alumina components of higher density and smaller grain size, substantially reducing the risk of fracture. The use of ceramics proliferated throughout Europe, although concerns about fracture, raised in the United States, resulted in its classification as a Class-III medical device by the U.S. Food and Drug Administration (FDA). These circumstances, coupled with the consequences of ceramic fracture, led to the dominance of polyethylene bearings for hip arthroplasty in the United States at the end of the twentieth century.

However, in the middle to late 1990s, concern about osteolysis secondary to polyethylene wear prompted a reevaluation of alternate bearings. The fracture rate of second-generation alumina was reported by ceramic producers to be reduced . . . [Full Text of this Article]
