Tolerability and Efficacy of 3 Approaches to Intra-articular Corticosteroid Injections of the Knee for Osteoarthritis

Abstract

Other studies have shown that the superolateral portal is the most accurate. This study did not assess accuracy, but it showed that all 3 knee injection sites studied have similar overall clinical benefit at 4-week follow-up. Procedural pain was not significantly different between groups.
