Background. Chronic periprosthetic joint infection (PJI) remains the one among the most severe complications of total hip arthroplasty. Presence of sinus tract assosiated with polymicrobial infection development, complexity of bacteriological diagnostics and damage of soft tissues lead to constrictions of one-stage revision hip arthroplasty (RHA). The aim of this studywas to assess the influence of draining sinus tract on the outcomes of one-stage RHA in patients with chronic hip PJI. Materials and Methods.A prospective cohort comparative study included 78 patients who underwent one-stage RHA in 2017-2020. Two groups were formed: 48 (61.54%) patients without sinus tract (WST) and 30 (38.45%) patients with sinus tract (ST). Results. The presence of a sinus tract significantly increased the duration of a one-stage RHA in groups of ST and WST (230 and 197.5 min respectively, p = 0.02), as well as blood loss (850 ml and 700 ml, respectively, p = 0.046). Sinus tract was a reliable symptom of soft tissue local infectious inflammation (86.67%, p = 0.00031), fasciitis (36.67%, p = 0.012), purulent cavity (66.67%, p = 0.00027). The structure of the pathogens was comparable. Monobacterial infections predominated in the WST group (82.98%) and in the ST group (77.78%, p = 0.08). In most cases staphylococci were isolated. The median follow-up was 20 months for both groups. The PJI was healed in 93.0% (n = 28) patients in WST group and 82.2% (n = 43) in ST PJI (p0.05). Postoperative evaluation in the WST and ST groups: HHS 92 and 90 points (p = 0.79), EQ-5D-5L – 0.82 and 0.78 points (p = 0.84) respectively. The proportion of patients who were indicated revision surgery with no PJI association in the ST group exceeded this indicator more than twice according to the WST group — 25 and 11.62%, respectively (p0.05). Conclusion.As a result of the study, there was no statistically significant difference between the outcomes of one-stage RHA in patients with and without sinus tract. Factors such as the anamnesis morbi, the soft tissues condition at the surgical site and the pathogenic microflora characteristics should be taken into account in order to achieve favourable outcomes of surgical treatment.
