INTERPRETATION There was a clinical ly relevant association between early migration of acetabular cups  and late revision due to loosening .
BACKGROUND AND PURPOSE The association between excessive early migration of acetabular cups  and late aseptic revision has been scantily reported .
We therefore performed 2 parallel systematic review s and meta-analyses to determine the association between early migration of acetabular cups  and late aseptic revision .
The ABG hydroxyapatite-coated hip prosthesis: one hundred consecutive operations with average 6-year follow-up.
One hundred consecutive ABG ( Anatomique Benoist Giraud , Howmedica ) hydroxyapatite-coated hip arthroplasties in 97 patients were evaluated prospect ively with a follow-up time of 4 to 10 years ( mean , 6 years ) . Clinical results were excellent with an improvement in the Merle d'Aubigne score from 9 preoperatively to 17.4 at 5 years . Thigh pain was persistent in only 3 % ; it was mild in nature and controlled with simple analgesics . Kaplan-Meyer survivorship analysis was 100 % for the femoral stem and 95 % for the acetabular cup at 6 years . Of concern was the high polyethylene wear measured with an average of 0.24 mm/y ( range , 0.05 - 0.76 mm/y )
