Wilson LA, et al. - Given a common use of intra-articular (IA) injections of corticosteroid (CO) and hyaluronic acid (HA) for osteoarthritis, researchers assessed trends over time and evaluated the impact of IA injections on postoperative chronic opioid use in total hip and knee arthroplasty (THA/TKA) via analyzing data from Truven Health MarketScan database (2012 to 2016). Throughout the study period, a decrease in preoperative CO and HA injection was observed in both THA and TKA. Greater odds of chronic opioid utilization were observed in TKA patients who received two or more preoperative CO injections, while decreased odds of chronic opioid use were observed among TKA patients with two or more HA injections in the year prior to surgery.
