AbstractThe aim of the study is to explore the impact of storage time on wear rates. Two groups of acetabular liners with a storage time of 1 and 4 years were tested on 2 hip simulators of the same type. There were 6 liners in each group. Gravimetric analysis was performed every 500 000 cycles for a total of 3 million cycles. The mean wear rate for the group of 4-year-old liners (36.3 mg/million cycles) was significantly higher than that for the 1-year-old group (23.1 mg/million cycles) (P < .05). After the last gravimetric analysis, scanning electron microscopy was used to observe the wear patterns of the bearing surfaces. This study found that wear resistance decreased as storage time increased.
