title: Polyethylene liner exchange of the Harris-Galante porous I and II acetabular components without cement: results and complications.
abstract: This study reviewed the long-term efficacy of the locking mechanism of the Harris-Galante porous (HGP) I and II acetabular components and the results and complications of polyethylene liner exchange without cement. There were 400 HGP-I components with a mean follow-up of 10 years (range, 2-19 years) and 78 HGP-II components with 8 years of mean follow-up (range, 2-13 years). There has been only 1 liner dislodgement (0.2%). Thirty-five hips (34 patients) have undergone liner exchange without cement. The index acetabular component was implanted as a primary procedure in 19 hips and a revision in 16 hips. No exchanged liner has dislodged at a mean follow-up time of 5.1 years (range, 2-11 years). However, there have been 7 patients (20%) with recurrent dislocation and all required reoperation. Dislocation was significantly lower when an elevated rim liner was used.
