Prolonged use of corticosteroid injections for knee osteoarthritis reduces cartilage volume .
This study has been identified as potentially high impact.
OE's AI-driven High Impact metric estimates the influence a paper is likely to have by integrating signals from both the journal in which it is published and the scientific content of the article itself.
Developed using state-of-the-art natural language processing, the OE High Impact model more accurately predicts a study's future citation performance than journal impact factor alone.
This enables earlier recognition of clinically meaningful research and helps readers focus on articles most likely to shape future practice.
Effect of Intra-articular Triamcinolone vs Saline on Knee Cartilage Volume and Pain in Patients With Knee Osteoarthritis: A Randomized Clinical Trial.
JAMA. 2017 May 16;317(19):1967-1975140 patients with symptomatic knee osteoarthritis (Kellgren-Lawrence grade II-III) and ultrasonographic evidence of synovitis were included in this trial to determine the effects of prolonged corticosteroid use on cartilage loss and pain. Patients were randomized to injections of triamcinolone acetonide or saline every 12 weeks for a period of two years. The outcomes assessed included cartilage loss and damage (MRI), pain, function, and adverse events. The results of this trial indicated that corticosteroid treatment led to a greater loss of cartilage at 2 years compared to the saline group, with no significant differences in pain outcomes between groups.
