Background:
The purpose of this study was to report clinical outcomes in patients who underwent revision surgery for glenoid baseplate failure after index reverse shoulder arthroplasty (RSA).
Methods:
A retrospective review was performed to identify patients from 2010 to 2020 at a single institution who sustained glenoid baseplate failure after RSA and underwent revision surgery. Exclusion criteria included periprosthetic joint infection or lack of minimum 1 year clinical and radiographic follow-up. Included patients were contacted for clinical outcomes (American Shoulder Elbow Surgeons (ASES), Visual Analog Scale (VAS) pain, Single Assessment Numeric Evaluation (SANE) and Patient Satisfaction scores).
Results:
A total of 24 patients were identified, and 22 out of 24 (92%) patients were available for clinical follow-up at a mean period of 3.4 years after final revision surgery. The mean age was 70 years, and 15 out of 22 (68%) patients were female. A total of 17 patients were revised to RSA, and five patients were revised to hemiarthroplasty. For the 22 included patients, the mean follow-up ASES score was 64.6, VAS pain was 2.4 and SANE was 58%, which were all significantly improved versus pre-revision. In total, 64% of patients were satisfied or completely satisfied.
Discussion:
Revision surgery after glenoid baseplate failure in RSA yields unpredictable clinical outcomes. Revision to RSA or hemiarthroplasty both resulted in modest functional results with persistent mild pain.
