Bank bone grafts in revision hip arthroplasty for acetabular protrusion

In 23 revision hip arthroplasties in which acetabular protrusion was encountered, homologous bone grafting was used to reconstruct or reinforce the medial wall of the acetabulum. Loosening of the acetabular component was the cause of the protrusion in all the cases. Postoperative follow-up showed a solid bone socket around the acetabular cup in all the cases and no signs of loosening at 3-years' follow-up.
