We studied the results for 168 available hips from a series of 324 consecutive primary total hip arthroplasties that had been performed with insertion of a Harris-Galante-I acetabular component without cement. The acetabulum had been reamed in a so-called line-to-line manner, and the cup had been fixed with one to four screws. A femoral component with a modular alumina-ceramic head had been inserted with cement in all hips. The median duration of follow-up was 112 months (range, 101 to 131 months).Of the original 324 hips, 109 could not be included in the clinical and radiographic follow-up because the patients had died and thirty could not be included because the patients were not available for examination. Seventeen hips had had a revision of the acetabular cup: five, because of infection; five, because of dislocation; three, because of aseptic loosening; and four, because of technical failure. This left 168 hips for clinical and radiographic follow-up; of these, fifteen had had a revision of the femoral component only. Of the remaining 153 hips, which had not had a revision, 147 (96 percent) were considered by the patient to have a satisfactory, good, or excellent result. One hip was found to have a loose cup on radiographic evaluation and was therefore considered to have failed, but the clinical function was good.We concluded that, with an overall rate of aseptic loosening of 1 percent (four of 324) after an intermediate (ten-year) duration of follow-up, use of this cup has good results.
