Study Overview
Brief Summary
Clinical manifestations of rotator cuff tear include shoulder pain, weakness, and stiffness. The level of pain is often a limiting factor when assessing shoulder range of motion and strength pre-operatively. Pain itself has even been a cause of weakness due to muscle atrophy.
The purpose of this study is to further understand the effect pain has by measuring constant shoulder scores in patients before and after ultrasound guided subacromial (the outer end of the shoulder blade) injection of lidocaine (a local anesthetic or numbing agent) compared to saline (salt solution), in patients indicated for arthroscopic rotator cuff repair. The saline and lidocaine has been approved for use by the U.S. Food and Drug Administration (FDA). The constant shoulder score includes your level of pain, activity level, range of motion and strength measures.

Arms & Interventions
Subacromial Lidocaine Injection
Both of your shoulders will be examined and evaluated (shoulder survey). Following the exam, you will be randomized (assigned by chance, similar to a coin toss) to receive a 10cc (2 teaspoon) subacromial injection of lidocaine, will be given under ultrasound (using sound waves) guidance to your affected shoulder. A repeat shoulder exam will be performed and recorded
Intervention: Lidocaine (Drug)
Subacromial Saline Injection
Both of your shoulders will be examined and evaluated (shoulder survey). Following the exam, you will be randomized (assigned by chance, similar to a coin toss) to receive a 10cc (2 teaspoon) subacromial injection of saline, will be given under ultrasound (using sound waves) guidance to your affected shoulder. A repeat shoulder exam will be performed and recorded
Intervention: Saline (Drug)
