This retrospective series from Mayo Clinic examined outcomes of glenoid component revision surgery after failed total shoulder arthroplasty. Forty-eight shoulders were followed at mean 4.9 years to determine whether reimplantation of a new glenoid component produces better outcomes than removal with bone grafting.
When you take a failed TSA back to the OR for glenoid revision, the single most important intraoperative decision is whether to reimplant a component or leave native bone with graft. This series provides the clearest available data on that choice: reimplantation yields satisfactory pain relief in 86% vs 66% with removal alone, with significantly higher patient satisfaction.
The key enabler of that decision is bone stock. The authors' classification — grading deficiencies as mild, moderate, or severe based on what fraction of the glenoid rim and surface remains. Gives you a framework to make that call intraoperatively. Mild and moderate deficiencies generally support reimplantation; severe central or combined loss often forces removal-only.
Do not treat this as an isolated glenoid problem. Two-thirds of these patients had additional pathology. Instability was present in 35% and must be addressed at the same sitting, or the new component will loosen again through eccentric loading.
If bone loss forces a removal-only procedure and the patient develops painful glenoid arthritis afterward, staged reimplantation after graft consolidation is a real option with good early results. Worth counseling patients on preoperatively.
