Clinical Fate of Glenohumeral Osteoarthritis Following Intraarticular Corticosteroid Injection: An Analysis in 311 Shoulders.

Approximately one third of glenohumeral OA patients who had received an intraarticular corticosteroid injection eventually elected to undergo shoulder arthroplasty within 3 to 8 years of the injection. High-grade arthritic changes in radiographs, female gender, and younger age were found to be independent factors associated with undergoing arthroplasty. This information may be useful in counseling patients about their future clinical course.Level of Evidence: Level III Retrospective comparative study.
