  • Title: Acetabular revision total hip arthroplasty using an impacted morselized allograft and a cementless cup: minimum 10-year follow-up.
    Author: Lee JM, Nam HT.
    Journal: J Arthroplasty; 2011 Oct; 26(7):1057-60. PubMed ID: 21592720.
    Abstract:
    This study was undertaken to analyze the clinical and radiologic results of acetabular revision arthroplasty using an impacted morselized allograft and a cementless cup and was performed on 71 hips of 62 patients who were followed up for a minimum of 10 years (10 years to 14 years 8 months; mean, 12 years). The acetabular bone defects were classified using the American Academy of Orthopaedic Surgeons Committee on the Hip and Paprosky classifications. Cementless hemispherical cups were inserted via a press-fit technique, using an impacted morselized allograft. The mean Harris hip score at the last follow-up visit was 92. Only 3 cases were re-revised, and the 12-year survival rate was thus 95.8%. The study shows that acetabular revision arthroplasty using an impacted morselized allograft and a cementless cup is an excellent treatment option.
