Long stem cemented revision arthroplasty for aseptic loosening in elderly patients produces good results, despite significant bone loss.

Abstract

We assessed the results of long cemented stems in patients over 65 undergoing a first time revision hip arthroplasty for aseptic loosening. 103 patients were followed up for a minimum of five years after revision surgery; 45% had EndoKlinik C grade preoperative bone loss. At final follow-up 31 patients had died, all but one with the prosthesis in situ. There were 71 revisions alive, one had been revised for a peri-prosthetic fracture. Of the 45 that had radiographs at a minimum of five years, three stems were probably or definitely loose according to the Harris classification. There was 92% patient satisfaction and a mean Oxford Hip Score (OHS) of 25/60 in the 59 patients that had not been revised and had full clinical follow-up. Long-stem cemented revisions for aseptic loosening in elderly patients allow immediate postoperative weight bearing and have good radiological and clinical outcomes.
