Study Evaluating Reverse Versus Anatomic Shoulder Arthroplasty Techniques in the Treatment of Osteoarthritis: Protocol
This study will compare total shoulder arthroplasty (TSA) reverse shoulder arthroplasty (RSA) procedures, in the context of a prospective, randomized-controlled trial to determine the optimal treatment in patients 65 years of age and older, and equal to or less than 15 degrees of glenoid retroversion, who have glenohumeral osteoarthritis.
• Patients who have failed standard non-surgical management of their idiopathic shoulder osteoarthritis who would benefit from a shoulder arthroplasty. Failed medical management will be defined as persistent pain and disability despite adequate standard non-operative management for 6 months. Medical management will be defined as:
‣ The use of drugs including analgesics and non-steroidal anti-inflammatory drugs
⁃ Physiotherapy consisting of stretching, strengthening and local modalities (ultrasound, cryotherapy, etc.)
⁃ Activity modification
• Imaging, and intra-operative findings confirming advanced glenohumeral cartilage loss
• Patients may present with a glenoid deficiency and \</=15 degrees of retroversion
• 65 years of age and older
