Cementless fixation in 2-stage reimplantation for periprosthetic sepsis

Twenty-five patients with documented infection of the hip were reviewed. All patients underwent reconstruction in a 2-stage fashion with cementless implants. The average follow-up in this group was 41 months. The average time to reimplantation was 4.8 months. Of the 25 living patients, 22 retained their implants. There were 2 recurrences of infection, for an infection recurrence rate of 8% (2 of 25). The average postoperative Harris Hip Score was 81. Bone ingrowth was confirmed radiographically via the Engh fixation score in all but 1 of the surviving implants. Cementless fixation in 2-stage reimplantation can result in acceptable eradication rates, while supplying predictable fixation, provided that appropriate cementless revision implants are used.
