Abstract
The purpose was to compare postoperative outcomes and functional improvement between patients with preoperative aER deficits vs. preserved aER function. There were 115 patients in the <0° aER group and 314 in the ≥30° aER group. Preoperative patients in the <0° group were worse for all measures except subjective pain while post-operatively, they had significantly greater improvement for all measures of motion. Postoperatively, both groups achieved comparable scores for forward elevation, pain, SST and ASES. This study demonstrates that patients with a complete aER deficit can recover substantial and comparable function after RTSA.
