MULTIPLE REVISION FOR FAILED CHARNLEY LOW-FRICTION ARTHROPLASTY

We reviewed 54 patients at a mean follow-up of 4 years 4 months after rerevisions for failure of Charnley low-friction arthroplasty. Rerevis ion for aseptic loosening in 26 hips was satisfactory; there were no c linical failures and at the latest radiological assessment only one st em and three sockets showed signs of loosening. By contrast, nine of 2 0 multiple revisions for recurrent dislocation failed, as did five of eight multiple revisions for deep infection, There was radiological ev idence of loosening in one stem and nine sockets in the former group a nd in three stems and five sockets in the latter.
