Review Question - QID 219955

A 51-year-old active accountant has had shoulder pain for the last 9 months that is preventing her from playing tennis at her country club. She has exhausted physical therapy, including a comprehensive rotator cuff strengthening protocol, and had a platelet-rich plasma (PRP) injection in the office 3 months ago that provided minimal relief. Radiographs and MRI of her affected shoulder are shown in Figures A-D. Clinically, she has no appreciable weakness on exam, but does have pain with Jobe and empty can testing, no tenderness over the AC joint, and negative cross-body adduction and O'brien's testing. Which of the following is the most appropriate treatment option to offer her at this time?
