Evaluation of The Standard Procedure for the Treatment of Periprosthetic Joint Infections (PJI) in Germany - Results of a Survey within the EndoCert Initiative
Abstract Background: The PJI is a severe complication in the field of arthroplasty.Despite the rising number of primary joint replacements, no therapeutic standard has been established for the treatment of PJI yet.Methods: A survey on the principles of treatment of PJI in Germany wasconducted. A total of 515 EndoProthetikZentren were included, resulting in a response rate of 100%.Results: For early infections 97.6% of the centers use DAIR. A one-stage exchange was implemented by less than 50% of the centers. If implemented, this treatment entails a prior selection of patients for a successful treatment. The two-stage exchange is performed in all centers, and most centers proceed with the implantation of a cemented spacer between stages. 75% of the centers proceed with a center-based concept for the treatment of PJI.Conclusion: The rising number of primary joint replacements underlines the importance of developing standards and harmonized definitions for the treatment of PJI. These standards have not yet been fully achieved. The most relevant treatment options in Germany are displayed. The two-stage revision with a cemented spacer is the most widely implemented treatment option in Germany. This summary of principles could serve as a basis for the development of standardized treatment guidelines and definitions.
