Acetabular revision in a total hip arthroplasty (THA) with pelvic discontinuity is uncommon and challenging. Optimal management remains controversial, particularly with graft and implant selection. Interpretation of outcomes is confounded by the heterogeneity of patterns of bone loss and the lack of long-term results in great numbers for any given choice of treatment. We report a revision THA using a press-fit bulk acetabular allograft and an uncemented porous-coated anatomic prosthesis for the management of pelvic discontinuity. After 20 years, the patient still had an excellent functional outcome with radiographic evidence of graft incorporation and no signs of loosening.
