title: Impacted autograft and cementless components in acetabular revision: a retrospective series.
abstract: OBJECTIVE
  A retrospective review of the short- to medium-term results of acetabular revision using impacted autograft combined with cementless acetabular components is reported.
  
  
  METHODS
  Twenty-five cases with aseptic acetabular loosening and associated bone defects were revised using impacted autograft and a cementless acetabular component.
  
  
  RESULTS
  Twenty-five patients were followed for a minimum of 4 years. Mean follow-up was 5.5 years (range 4.0-8.0 years). Radiographs showed that good incorporation of autograft occurred in all cases. Mean Harris hip score improved from 36.0 points (range 20.0 to 50.0) pre-operatively to 85.7 points (range 50.0 to 91.0) at latest follow-up. Outcome was Excellent in 8 cases, Good in 13 cases and Fair in 4 cases. No cases required further revision.
  
  
  CONCLUSIONS
  The use of impacted autograft in combination with cementless components for acetabular revision can achieve good short- to medium-term result in patients with acetabular bone deficiency.
