Abstract
Introduction: The impending burden of revision shoulder arthroplasty has increased interest in outcomes of revision procedures. Glenoid component removal and conversion to a hemiarthroplasty (HA) is an option for aseptic glenoid loosening after anatomic total shoulder arthroplasty (aTSA).
Methods: Patients who underwent revision shoulder arthroplasty over a 15-year period were identified. Pre-surgical and operative data were analyzed for 17 patients who met inclusion and exclusion criteria. Patients were contacted at a mean follow-up of 70 months from revision surgery for functional outcomes scores, reoperations, and implant survival.
Results: Implant survival was estimated to be 88% at 2 years and 67% at 5 years. Mean ASES score for surviving implants was 58 ± 22. Mean SANE score was 54 ± 24, and mean VAS pain score was 3.5 ± 2.8. Mean SF-12 Mental and Physical scores were 46 ± 15 and 38 ± 10, respectively. Five patients (50% of those with surviving implants) reported being either satisfied or very satisfied with the status of their shoulder. Complications were seen in 6 patients (35%) and 5 patients (29%) required reoperation.
Conclusions: HA following failed aTSA due to glenoid loosening produced modest clinical results and satisfaction rates. Reverse arthroplasty may be a more reliable treatment strategy in this patient population.
