title: Harris-Galante II acetabular cup: a survival analysis.
abstract: OBJECTIVE
  To determine the survival rate of the Harris-Galante (HG) II cup and identify factors contributing to failure.
  
  
  METHODS
  271 primary total hip arthroplasties (THAs) performed between 1992 and 1999 in our hospitals using the HG II acetabular cup were retrospectively reviewed due to a high incidence of liner dissociation.
  
  
  RESULTS
  48 THAs were revised, 32 (67%) of which were due to liner dissociation. The Kaplan-Meier 10-year survival rate was 73%. Dislocation (p<0.001) and acetabular size (p=0.042) were independent predictors of acetabular component failure in the Cox's regression model.
  
  
  CONCLUSIONS
  The long-term outcome of the HG II cup is unsatisfactory. Although the HG II cup is no longer produced, numerous patients have this prosthesis in situ and should be reviewed regularly, as liner dissociation and retroacetabular osteolysis may occur.
