Effect of intra-articular steroids on deep infections following total knee arthroplasty.

Intra-articular steroids have been commonly used for the treatment of arthritis. The aim of our study was to discover any relation between deep infections following total knee arthroplasty and intra-articular steroid use before the arthroplasty. We undertook a retrospective matched cohort study. In the study group there were 32 patients with confirmed deep infection following total knee replacement. The control group consisted of 32 patients with no evidence of infection in the knee. There was no significant difference between the numbers of patients who received intra-articular steroid injection between the groups (P=1). We believe that infection following total knee replacement is due to multiple factors and that the use of intra-articular steroids does not alter the incidence of deep infections following total knee arthroplasty.
