RESUMEN
Two-stage exchange in infected total knee arthroplasty is a reliable technique, but it has a high rate of blood loss. The study aims to compare the pre-operative and post-operative haemoglobin levels, the rate of transfusion, and the blood loss in two-stage exchange. From July 2018 to July 2019, eighteen patients underwent two-stage exchange of their infected total knee arthroplasty. Local and systemic tranexamic acid was administered in both surgical stages. Calculated blood loss was 2246 mL (range 1528 - 2850) in the first stage and 2388 mL (1873 - 2829) during reimplantation, respectively. The corresponding transfusion rate was 55 % and 67%, respectively. With the numbers available, these differences were not significant. In conclusion, this study shows that the blood loss and transfusion rate are similar during the two stages of exchange knee arthroplasty for infection.

Over the past decade, the incidence of revision arthroplasty due to infection has increased substantially, often resulting in multiple surgical interventions with variable success rates and poor clinical outcome. Intraoperative wound irrigation has been proposed to reduce bacterial bioburden and contamination, but currently there is no widely accepted recommendation for the use of topical antiseptics, whether as separate molecules or as a mixed solution. We reviewed studies regarding the use of intraoperative topical antiseptics, their security profile and efficacy in preventing and treating infections of orthopedic implants and introduced a possible combination that may prove valuable in the future.
