The two and five year implant revision-free survival was 99%. The two and five year re-operation-free survival was 97%. Eighteen (24%) glenoid components required augmentation with corticocancellous autograft from the humeral head. There were two cases of glenoid loosening with gross changes in position. Patients experienced significant pain relief with a 92% satisfaction rate. Shoulder elevation and external rotation improved from 65 and 21 degrees pre-operatively to 138 and 45 degrees post-operatively, respectively (p < .01). Average ASES and SST scores were 72 and 7.0, respectively. The use of prednisone, DMARDs, or biologic medications had no significant impact on outcomes.
