ABSTRACT
BACKGROUND: Glucocorticoids have been widely used in perioperative period for postoperative pain relief after total knee arthroplasty (TKA). However, the optimal administration protocols of glucocorticoids remain controversial. This study aims to compare the efficacy of glucocorticoids between intravenous and periarticular injection on clinical outcomes.
METHODS: A total of 114 patients were randomly assigned to intravenous (IV) group (n = 57) and periarticular injection (PI) group (n = 57). The IV group received 10 mg dexamethasone intravenously and the PI group received periarticular injection of 10 mg dexamethasone during the procedure. The clinical outcomes were assessed using visual analogue scale (VAS), knee society score (KSS), range of motion (ROM), knee swelling, inflammation markers and complications after TKA.
RESULTS: The VAS score during walking at 2nd day postoperatively was lower in the PI group compared with the IV group (2.08 ± 1.45 vs 2.73 ± 1.69, p = .039), and there was no significant difference at the other time points of VAS score in two groups. The inflammation markers, knee swelling, knee ROM and KSS score were not statistically different. Vomiting and other complications occurrence were not significantly different between the two groups.
CONCLUSIONS: Intraoperative periarticular injection of glucocorticoids has similar analgesic effect compared to intravenous in the postoperative period following TKA and may be even more effective on the second postoperative day. In addition, periarticular injection of glucocorticoids does not impose an excess risk or complication on patients.
