PURPOSE: To employ a national database to evaluate the association between intraoperative corticosteroid injection at the time of ankle arthroscopy and @entity86 rates in Medicare @entity1 . METHODS: A national insurance database was queried for Medicare @entity1 who underwent ankle arthroscopy, including arthroscopic @entity12458 , synovectomy, and limited or extensive debridement. Two groups were created: ankle arthroscopy with concomitant local @entity479 injection (n  = 459) and a control group of @entity1 who underwent ankle arthroscopy without intraoperative local @entity479 injection (n  = 9,327). The demographics and Charlson Comorbidity Index of each group were compared. Infection rates within 6 months postoperatively were assessed using International Classification of Diseases, 9th revision, and Current Procedural Terminology codes and compared between groups using   (2)-tests. RESULTS: A total of 9,786 unique @entity1 who underwent ankle arthroscopy were included in the study. There were no statistically significant differences between the @entity479 injection study group and controls for the assessed infection-related variables, including gender, age group, @entity28 , smoking, and average Charlson Comorbidity Index. The infection rate for @entity1 who had a local @entity479 injection at the time of surgery was 3.9% (18/459 @entity1 ), compared with 1.8% (168/9,327 @entity1 ) in the control group (odds ratio, 2.2; 95% confidence interval, 1.4 to 3.7; P  = .002.) The majority of this difference was noted between the 65 and 79 years age groups. CONCLUSIONS: The use of intraoperative intraarticular corticosteroid injection at the time of ankle arthroscopy in Medicare @entity1 is associated with significantly increased rates of @entity86 compared with controls without intraoperative @entity479 injections. LEVEL OF EVIDENCE: Level IV, therapeutic case series.
