Acetabular components without bulk bone graft in revision surgery: A 5- to 13-year follow-up study.
Eighty-three consecutive revisions in 74 patients using a porous-coated acetabular component without bulk bone graft were followed up for an average of 9.3 years (range, 5-13 years). A large-diameter cup was implanted in hips with adequate osseous support, and a high hip center technique using a standard- or smaller-diameter cup was selected in hips without sufficient bone stock. Acetabular bone deficiency was segmental in 18 hips, cavitary in 30, and combined segmental and cavitary in 35. Four (5%) cups were revised again; 1 for infection, 1 for dislodgement of the polyethylene liner from the metal shell, and 2 for recurrent dislocation. No acetabular components were categorized as definitely loose at final follow-up. The current satisfactory results encourage the use of this simple technique.
