## Abstract Wear performance and debris‐size distribution of vitamin E (DL‐α 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 b
The size and morphology of particulate wear debris retrieved from tissues around 18 failed total knee replacements (TKR) were characterized. Interfacial membranes from nine cemented and nine uncemented TKR were harvested from below the tibial components during revision surgery. Wear debris were extr
