Reverse shoulder arthroplasty in patients with rheumatoid arthritis.

Background: The purpose of this study was to describe the pathoanatomy of patients diagnosed with rheumatoid arthritis and rotator cuff deficiency and report their outcomes following reverse shoulder arthroplasty.

Methods: Twenty-one shoulders were evaluated prospectively. Nine had no prior surgery, 9 had a failed rotator cuff repair, and 3 had a failed arthroplasty.

Is a formal physical therapy program necessary after total shoulder arthroplasty for osteoarthritis?

Hypothesis: A retrospective analysis was conducted of 2 consecutive groups of patients undergoing total shoulder arthroplasty (TSA) for primary osteoarthritis. One group was treated with formal physical therapy (PT), and one group was treated with home-based, physician-guided PT. We hypothesized that patients with a formal postoperative PT protocol would have significantly better postoperative clinical outcomes than patients with no formal PT.

Revision reverse shoulder arthroplasty for glenoid baseplate failure after primary reverse shoulder arthroplasty.

Background: The aim of this study is to document a single surgeon's experience performing revision reverse shoulder arthroplasty after baseplate failure.

Methods: Revision reverse shoulder arthroplasty (RSA) for mechanical failure of the glenoid baseplate after RSA was performed in 14 patients. Clinical and radiographic data were collected preoperatively, prior to baseplate failure, after baseplate failure, and at latest follow-up after revision (average, 33 months).
