This retrospective cohort study tracks 27 patients (28 shoulders) who underwent shoulder hemiarthroplasty for glenohumeral osteoarthritis at a single institution, reporting outcomes at an average of 17.2 years — one of the longest follow-up series available. It asks whether long-term satisfaction, revision rates, and functional outcomes differ based on glenoid wear pattern (concentric vs. eccentric) and osteoarthritis etiology (primary vs. secondary).
When counseling a patient with glenohumeral osteoarthritis about hemiarthroplasty, these data — nearly three-quarters unsatisfied and nearly one-third revised at 17 years.
Should anchor the conversation: eccentric posterior glenoid wear and secondary osteoarthritis etiology predict the worst outcomes, and younger age predicts higher revision risk.
In a shoulder with an intact rotator cuff, this study supports favoring total shoulder arthroplasty as the index procedure rather than planning hemiarthroplasty with intent to convert, given that conversion arthroplasty itself carries high failure rates.
