Abstract EN
Using morselized and structural allograft to restore bone stock for massive acetabular bone defect in revision total hip arthroplasty (THA) is an appealing procedure.
However, concerns about inability to achieve long-term stability following allograft resorption remained.
From 2003 to 2012, 59 hips in 58 patients undergoing revision THA for Paprosky type II or III acetabular defects were retrospectively reviewed.
The acetabular defects were managed with deep-frozen morselized and structural allografts, and a press-fit cementless cup along with supplementary screws.
Clinical outcomes and radiographic results were analyzed with a mean follow-up of 8.7 years.
The clinical successful rate was 100% for hips with Paprosky type II defect, 95.2% for IIIA defect, and 92.8% for IIIB defect.
Three hips with type III defect failed at 4, 7, and 9 years, respectively.
Harris Hip Score improved significantly from 60.1 preoperatively to 91.3 at the latest follow-up.
All hips with good clinical results showed trabecular bridging in the allograft-host bone interface.
Deep-frozen structural and morselized allograft in combination with a press-fit cementless cup represented a viable option to reconstruct acetabular defects in revision THA.
