Abstract:
Because the UHMWPE components fabricated by the historic process of gamma-sterilization in air are no longer marketed, a surgeon who wishes to continue performing joint replacement surgery must choose among the new polyethylenes, or he or she may choose a modern metal-metal or ceramic-ceramic bearing, each of which has its potential advantages and disadvantages (Table 4). Ultimately, it is the responsibility of the surgeon to assess the risk-benefit ratios of each of the new bearing combinations and make an informed and wise choice among them.
