This randomized trial seeks to investigate the difference if any between cortisone injection
versus bone marrow aspirate injection in the glenohumeral joint of patients with confirmed
osteoarthritis. The investigators hope that results from a prospective randomized controlled
pilot study on bone marrow aspirate (BMA) glenohumeral joint (GHJ) injections will provide
valuable early information on an alternative treatment for GHJ osteoarthritis (OA). This
novel study will also contribute clinical data to the growing pool of research around BMA in
the treatment of osteoarthritis. This study has the potential to uncover a new and more
effective therapy to add to the arsenal of an orthopaedic surgeon in the management of GHJ
OA. This would provide improved care and treatment for those disabled by GHJ OA.
Additionally, this knowledge would be applicable to a variety of medical practitioners who
treat GHJ OA from the general orthopaedic surgeon to pain subspecialists.
