Predicting Response to Intra-Articular Corticosteroid Injection in Patients With Osteoarthritis of the Glenohumeral Joint

Predicting Response to Intra-Articular Corticosteroid Injection in Patients With Osteoarthritis of the Glenohumeral Joint

This study will examine the effectiveness of a single cortisone injection in patients with shoulder osteoarthritis over a 6-month period, and identify clinical and radiographic factors to help predict how a patient with shoulder osteoarthritis will respond to a cortisone injection utilizing ultrasound guidance.

The purpose of this study is to assess the effectiveness of intraarticular corticosteroid injections (IACSI) for glenohumeral arthritis by 1) through patient-reported outcomes and 2) identifying clinical and radiographic predictors of IACSI success.

Inclusion Criteria:

• Patients with a diagnosis of symptomatic primary osteoarthritis of the shoulder will be recruited from the patient population seeking treatment at the Orthopaedics Sports Medicine Institute.
• those who have failed previous treatment including over-the-counter analgesics and activity modification
• have elected to receive a medically-indicated, ultrasound-guided IACSI in the shoulder.

Exclusion Criteria:

• Patients will be excluded from the study for any of the following reasons:
• Post traumatic osteoarthritis
• Inflammatory osteoarthritis
• Imaging confirmed rotator cuff tear
• Prior ipsilateral shoulder surgery
• Memory loss or inability to complete study measures
• History of allergy to injection medications
• Diabetic patients with patient-reported fasting blood glucose >200
• Prior injection in the ipsilateral shoulder within three months
