Intra-articular Injections of the Hip and Knee With Triamcinolone vs Ketorolac: A Randomized Controlled Trial

摘要

Background: Clinicians commonly utilize intra-articular injections to treat symptomatic primary arthritis. Steroid injections are common yet have immune-modulating effects and can alter gene expression which may delay definitive arthroplasty and further damage cartilage. Nonsteroidal anti-inflammatory injections may offer a safer profile due to their differing mechanism of action; however, there is a relative dearth of information regarding their efficacy. This noninferiority study compares the effectiveness of triamcinolone vs ketorolac in treating symptoms of moderate to advanced primary osteoarthritis of the hip and knee.
