The purpose of this study is to determine the most effective intraarticular steroid dose for
the treatment of glenohumeral osteoarthritis. The investigators aim to randomize patients
into low, medium, and high dose groups of injectable corticosteroids as these doses are
typically used in the standard of care for our patients. To date there has been no study to
evaluate which dose is most efficient with the fewest side effects for glenohumeral
osteoarthritis. The investigators objective will be to provide ultrasound guided
intraarticular glenohumeral injections of these randomized concentrations and to evaluate
pain and function before and following injection with the Shoulder Pain and Disability Index
(SPADI). The investigators hypothesize that the low dose steroid will provide equivalent
improvement of the pain and function to the medium and high doses, while minimizing side
effects.
