Risk Factors for Periprosthetic Infection after Large Joint Arthroplasty

Risk factors for the development of purulent complications after large joints arthroplasty were studied by the results of 3641 operations (3210 patients). Hip, knee, shoulder and elbow arthroplasty was performed in 2523, 881, 105 and 132 patients, respectively. Hip and knee revision replacements were performed in 221 cases and in 492 cases surgical interventions were performed for dysplastic coxarthrosis, congenital and acquired deformities, under conditions of bone tissue deficit and other complicated cases. Three hundred fifty one patients were operated on due to acute injury. Periprosthetic infection was diagnosed in 58 cases (1.59%). It was stated that risk factors for periprosthetic infection development included severe concomitant pathology (diabetes mellitus,operations somatic diseases, degree of their severity and duration, HIV infection and other conditions), surgical interventions for dysplastic coxarthrosis and complex total hip replacement. In those cases the risk of complications increased by 1.5-3.5 times. Pyo-inflammatory process in the area of hip joint in history as well as every repeated surgery on the hip increased therisk of postoperative complications significantly. No differences in complication rate depending on the type of fixation and implant manufacturers were noted.
