Primary total hip replacement with a noncemented acetabular component: minimum 5-year clinical follow-up. Academic Article uri icon

Overview

abstract

  • The results of 123 total hip replacements with a noncemented Harris-Galante I acetabular component were reviewed (minimum 5-year clinical follow-up). The average clinical follow-up was 7 years (range, 5-10.8 years). No acetabular components were revised for loosening. One cup was revised for recurrent dislocation. In 3 cases, the acetabular liner was replaced at the time of femoral component revision (aseptic loosening), and in 1 case, a liner was revised because of recurrent dislocations. Of the hips, 92 had a complete set of radiographs for analysis. None of the acetabular components had migrated. Of the 92 acetabular components, 90 were considered radiographically stable (98%). Of these hips, 24 had linear radiolucencies of < or =2 mm in < or =2 of 4 zones and were considered stable. Two cups (2%) were considered possibly unstable. One of these had a linear radiolucent line in 3 zones, and the other had an osteolytic lesion measuring 6 x 11 mm in greatest dimensions. No acetabular components were definitely unstable. The average Harris Hip Score improved from 50 points (range, 17-89 points) preoperatively to 95 points (range, 74-99 points) at the latest follow-up examination. The average Hospital for Special Surgery hip score improved from 21 points (range, 10-31 points) preoperatively to 38 points (range, 27-40) at the last follow-up examination. Noncemented acetabular fixation with the Harris-Galante I component showed excellent clinical results at a minimum of 5 years' follow-up.
