Ann Fam Med. 2013;11(3):229–237.](http://www.annfammed.org/lookup/volpage/11/229) In Table 1, under Solution, the components for intra-articular 25% dextrose erroneously contained 1% saline. There is no saline in the intra-articular injection, just the specified 5 mL 50% dextrose and 5 mL 1% lidocaine. * © 2013 Annals of Family Medicine, Inc.
