摘要：

Wear performance and debris-size distribution of vitamin E (DL-alpha tocopherol, VE)added ultrahigh molecular weight polyethylene (UHMWPE) was evaluated using a knee-simulator test. VE was mixed with GUR 1050 UHMWPE powder at 0.3 wt%, and the tibial components of the knee joint were made by direct compression molding. The VE-added UHMWPE showed consistently lower wear volume throughout the test. (c) 2007 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.
