AB0864 DO CORTICOSTEROIDS AND HYALURONIC ACID INJECTIONS CAUSE INFECTIONS? A SYSTEMATIC REVIEW OF LITERATURE ON ADVERSE EFFECTS AND INFECTION RATES OF INTRA-ARTICULAR CORTICOSTEROID AND HYALURONIC ACID INJECTIONS IN PATIENTS WITH KNEE OSTEOARTHRITIS
Background:Knee osteoarthritis has been a leading cause of chronic pain and disability in our increasingly aging population. Conservative management options of physiotherapy and oral analgesics offer some relief, but delivery of intra-articular injections such as corticosteroids or hyaluronic acid has increasingly become the mainstay of pain management of knee osteoarthritis. In a clinical setting, intra-articular injections offer a means to delay a total knee replacement. Despite the abundance of literature on corticosteroids and hyaluronic acid, there is no known percentage of infection rates or adverse effects that clinicians may use to inform patients prior to obtaining consent for the injection.Objectives:To determine a rate of adverse events and infection rates in patients undergoing intra-articular injections of corticosteroids or hyaluronic acid.Methods:A systematic review of current literature including studies involving patients ranging from 45 patients (Carmona L, 2018) to Cochrane reviews of 1767 patients (Campbell Kirk, 2015). From these studies, the number of patients, adverse reactions (i.e. pain, erythema) and serious adverse reactions (infections) were calculated.Results:Within our study, there was a large variation of numbers of adverse effects of hyaluronic acid and corticosteroids amongst studies, with percentages as variable as 0-9.3%. Corticosteroids demonstrated 11-26% reduction of adverse events compared to hyaluronic acid. However, confidence intervals were found to not be statistically significant.Conclusion:Intra-articular injections of corticosteroids and hyaluronic acid, although deemed clinically effective, continue to demonstrate variable rates of adverse effects and infection amongst patients with progressive knee osteoarthritis.Disclosure of Interests:None declared
