Structural and Morselized Allografting Combined with a Cementless Cup for Acetabular Defects in Revision Total Hip Arthroplasty: A 4- to 14-Year Follow-Up

<div>A 69-year-old female patient, with aseptic loosening of right bipolar hemiarthroplasty with acetabuli protrusio. (a) Preoperative radiographs showed up-and-in migration of the bipolar prosthesis with violation of Kohler’s line (Paprosky IIIB). (b) The acetabular component was revised with structural and morselized allograft and Trilogy cup. (c) Loosening of the acetabular component at 7 years after 1st revision THA. (d) The 2nd revision was undertaken by allogenous bone grafting again and a titanium porous revision cup. Radiography at 6 years showed stable cup position and good incorporation of allograft.</div>
