Increased Use of Intra-Articular Steroid Injection to Treat Osteoarthritis is Associated With Chronic Opioid Dependence After Later Total Knee Arthroplasty But Not Total Hip Arthroplasty.

Background: Intra-articular (IA) injections of corticosteroid (CO) and hyaluronic acid (HA) are commonly used for osteoarthritis. The efficacy of these interventions is controversial. Furthermore, research regarding the potential association of IA injection with later postoperative pain trajectories is lacking.

Methods: We performed analysis on Truven Health MarketScan database (2012-2016) in total hip arthroplasty (THA) and total knee arthroplasty (TKA). Trends over time were assessed. Multivariable logistic regression analyses were executed to evaluate the impact of IA injections on postoperative chronic opioid use.

Results: Preoperative CO and HA injections decreased throughout the study period in both THA and TKA. Preoperative CO and HA injections, regardless of frequency, had no significant impact on the odds of THA patients becoming chronic opioid users postoperatively. TKA patients who had 1 CO injection in the year before surgery experienced lower odds of postoperative chronic opioid use (odds ratio [OR], 0.89; 95% confidence interval [95% CI], 0.82-0.97), whereas patients who had 2 or more CO injections experienced significantly greater odds (OR, 1.14; 95% CI, 1.04-1.24). TKA patients who received 2 or more HA injections before surgery had significantly lower odds of chronic opioid use (OR, 0.90; 95% CI, 0.81-0.99).

Conclusion: The utilization of IA injections in patients with hip and knee osteoarthritis appears to be decreasing over time. TKA patients who received 2 or more preoperative CO injections experienced greater odds of chronic opioid utilization, whereas TKA patients with 2 or more HA injections in the year before surgery had decreased odds of chronic opioid use.
