The Risk of a Deep Infection Associated With Intraarticular Injections Before a Total Knee Arthroplasty

摘要

The aim of the study is to identify the risks associated with an intraarticular injection before a total knee arthroplasty (TKA). A total of 1628 patients were retrospectively studied over a 7-year period. The patients were divided into 2 groups: patient who received an intraarticular injection before a TKA and patients who did not receive an injection before a TKA. There were 16 deep infections identified (0.98%). Ten deep infections were identified in the patients who did not receive an injection before a TKA (1.18%), and 6 deep infections were identified in patients who received an injection before a TKA (0.77%). There does not appear to be a correlation with the timing of the injection before surgery and increased risk of infection. (C) 2016 Elsevier Inc. All rights reserved.
