摘要：
FIELD: medicine.SUBSTANCE: through a trocar inserted into the joint cavity, biomaterials are sampled for research by alternate evacuation of the joint aspirate with a syringe through the central channel of the trocar. The biofilm is taken from the implanted endoprosthesis surface by directing a cylindrical brush attached to an elastic wire element through the central channel of the trocar, and moving along the endoprosthesis surface in the "back-forward" direction. During the bacteriological study, the quantitative values of optical densities of the cultured biofilm obtained from the endoprosthesis surface Kbiop. and articular aspirate Kasp. are determined. During the cytological study, the neutrophilic leukocyte count in articular aspirate L. is determined. The coefficient K is calculated according to the proposed formula. At K≥2 and L≥3600/mcL the endoprosthesis is remove followed by a two-stage surgical treatment, including installation of an articulating antibacterial spacer and endoprosthesis replacement. At K≤1 and L≥3600/mcL the endoprosthesis components are replaced with sanation and drainage of the infection focus. At 1
