Shields E, et al. - In this study, authors estimated the data to assess the outcomes after conversion of anatomic total shoulder arthroplasty (aTSA) to reverse total shoulder arthroplasty (RTSA) vs a matched cohort. At final follow-up, they noticed similar visual analog scale pain (2.4 ± 2.8 vs 1.7 ± 2.8) and American Shoulder and Elbow Surgeons (68 ± 26 vs 76 ± 24) scores. They observed worse subjective shoulder value scores (63 ± 30 vs 79 ± 21), satisfaction (74% vs 90%), and more complications (31% vs 13%) in the revision group.
