Abstract
Aim: We studied changes in opioid prescriptions and corticosteroid injection use for knee osteoarthritispatients before and after intra-articular hyaluronic acid (HA) useand opioid prescriptions before and after knee arthroplasty (KA). Materials &methods:A total of1,017,578 knee osteoarthritis members were ascertained from a commercial claims database (Health Intelligence Company LLC, IL, USA) using ICD9/ICD10 diagnosis codes. Results:Eighty two percent of HA patients did not fill opioid prescriptions postinjection, with 54% of opioid users discontinuing fills. Two-thirds of KA patients filled opioid prescriptions within 6months postsurgery, with 78% of opioid users continuing fills and 62% of nonusers initiating use. Conclusion: Alternative therapies, such as HA, that reduce opioid use may alleviate opioid addiction risks for KA patients who use opioids in the pre- and postoperative periods.
