Hemostasis test parameters in patients requiring revision knee arthroplasty

Objective: comparative analysis of the blood coagulation system in patients requiring revision arthroplasty of the knee joint in connection with the developed infectious and aseptic complications after total arthroplasty. Material and Methods. 37 patients with complications of total knee replacement were examined. Patients were divided into 2 groups: 1st - with signs of suppuration (n=19); 2nd - with signs of aseptic instability of the endoprosthesis components (n=18). The control group consisted of 22 conditionally healthy people. Studied screening coagulation: activated partial thromboplastin time, prothrombin time, fibrinogen concentration, thrombin time, antithrombin III, protein C, the content of soluble fibrin-monomer complexes and D-dimers. Results. There was an increase in activated partial thromboplastin time in patients of group 2, prothrombin time - in patients of groups 1 and 2 compared with the data obtained in the control group (p
