Abstract
In this study, 40 patients who underwent total hip arthroplasty (THA) and had a history of previous steroid injections were compared retrospectively with 40 carefully matched patients who underwent THA in the same period but had never received steroid injections. The development of sepsis under standard care was one of the outcome measures. This occurred in 20% of steroid patients within the first 36 months after THA, compared to 0% in the control group. Further, in a detailed analysis of Harris and Oxford scores, patients treated with steroid had a higher incidence of night pain, more severe pain, and greater loss of function in activities of daily living at one year. There were two revisions for deep infection in the steroid and control groups.
Based on the incidence of pain and infectious complications in the first postoperative year, and pending completion of the study, we provisionally suggest that steroid injection of hips may be ill advised in patients who are likely candidates for future THA.
