Two-stage revision hip arthroplasty in the treatment of periprosthetic joint infection

Introduction. One of the rare complications following hip arthroplasty is periprosthetic joint infection (PJI). Two-stage revision arthroplasty is the gold standard in the treatment of deep periprosthetic infection of large joints, providing high probability of infection process resolution as well as functional recovery of the limb and elimination of pain syndrome.Aim: to improve the treatment results of patients with periprosthetic infection after primary hip arthroplasty.Materials and Methods. 121 patients (62 patients in the main group and 59 in the control group) after primary hip arthroplasty were included in the study. In the main group, treatment was performed using a two-stage technique with implantation of a preformed spacer and our proposed algorithm. In the control group, treatment was performed using a homemade spacer and without using the developed algorithm.Results. When using our developed treatment algorithm, a good result in the treatment of UTI was achieved. The infectious process was controlled in 80.6 % of cases, as compared with 64.4 % in the control group, which is comparable with the data of domestic and foreign literature.Conclusion. Treatment of patients with periprosthetic infection should be performed only in specialized centers that perform all stages of treatment, have all necessary instruments, an equipped operating room, necessary drugs in the hospital pharmacy, experienced staff and equipped bacteriological laboratory, as well as many years of experience of surgeons with these patients.
