Figs. 2-A, 2-B, and 2-C Lateral shoot-through radiographs of the left hip.



Figs. 3-A and 3-B Twelve months following surgery, the E1 acetabular liner with the fractured rim and acetabular cup was retrieved and sent to the laboratory.



Anteroposterior (Fig. 4-A) and lateral shoot-through (Fig. 4-B) radiographs six weeks after the second revision.



The vitamin E profile following the E1 retrieval after twelve months of implantation shows no decrease in vitamin E content at the surfaces of the rim or at the articular surface.



The carbonyl profile shows lipid absorption to a depth of 0.5 mm below the articular surface and no measurable oxidation in the E1 acetabular liner after twelve months of in vivo service.
