Long-term Intra-articular Steroid Injections and Knee Cartilage

Abstract

To the Editor Dr McAlindon and colleagues investigated the long-term effects on cartilage of intra-articular corticosteroid injections in the knee every 3 months for 2 years in people with knee osteoarthritis.¹ With respect to the clinical outcome, we agree with the authors that the usual short-term benefits after the injections probably were missed.
