Abstract
Introduction and purpose: Two-stage reimplantation of a hip replacement is the treatment of choice for deep periprosthetic infections. The purpose of this study is to analyse the survival of the femoral component in two-stage hip replacement reimplantations and compare the results of cemented and cementless components.
Materials and methods: Between 1988 and 1998 our hospital carried out 169 two-stage reimplantations for treatment of first episodes of deep infection. The femoral component was cemented in 121 cases and cementless in 48. All patients were followed up clinically and radiologically for at least five years.
Results: The two-stage revision was associated with a significant clinical improvement. The reinfection rate was 9% (16/169), of which 11 patients underwent revision surgery and five received chronic suppressive antibiotic treatment. Eight patients required revision due to aseptic loosening and two for periprosthetic fracture. With the numbers available, fixation with or without cement showed no significant differences.
Conclusions: The two-stage revision of an infected hip prosthesis resolved the infection in 91% of the cases. An additional 5% required revision due to aseptic loosening. The surgical outcomes seem to be independent of the femoral component fixation (cemented or cementless).
