Administration of a Methylprednisolone Taper and Complication Rates Following Total Knee Arthroplasty: A Multicenter Retrospective Study.

Background: Most patients undergoing total knee arthroplasty (TKA) report moderate to severe pain in the acute postoperative period. Recent preliminary data have suggested that a short course of oral corticosteroid may improve early postoperative pain after various orthopedic operations, but the safety of this practice has not been rigorously evaluated in larger patient populations. The purpose of this study was to evaluate complication rates in patients receiving a methylprednisolone taper (MT) vs controls after primary TKA. Methods: Records were reviewed for patients undergoing primary TKA from 2018 to 2023 by 2 surgeons at different institutions who began routinely prescribing a 6-day MT to patients without a contraindication or poorly controlled diabetes. The primary outcome of periprosthetic joint infection at 90 days and final follow-up was assessed as were secondary outcomes of surgical site infection and wound complications. A total of 930 patients were included in the study, with 641 patients in the control cohort and 289 patients in the methylprednisolone cohort. Results: There were no significant differences between the methylprednisolone and control cohorts in 90-day periprosthetic joint infection (0.7% vs 0%, Conclusions: MT following TKA did not significantly increase rates of wound complications or infections in this multi-institutional retrospective cohort study. This study provides preliminary evidence regarding the safety profile of a short duration of postoperative oral corticosteroids following TKA.
