Key result
rTSA predicts decreased ability to tuck in shirts and put on coats versus aTSA.
Why the study?
Equivalence in composite patient-reported outcomes between aTSA and rTSA for glenohumeral osteoarthritis fails to highlight nuanced effects on specific daily activities.
Does reverse total shoulder arthroplasty compared to anatomic total shoulder arthroplasty affect specific daily tasks in patients with glenohumeral osteoarthritis?
Population

Does reverse total shoulder arthroplasty compared to anatomic total shoulder arthroplasty affect specific daily tasks in patients with glenohumeral osteoarthritis?
p-value: p=>0.15
While composite patient-reported outcomes are similar between anatomic and reverse total shoulder arthroplasty, reverse TSA is associated with greater difficulty in specific overhead and behind-the-back activities.
Hill et al. (2025) conducted a cohort in Glenohumeral osteoarthritis (GHOA) (n=317). Reverse total shoulder arthroplasty (rTSA) vs. Anatomic total shoulder arthroplasty (aTSA) was evaluated on Composite patient-reported outcome scores (ASES, WOOS, SANE) and individual component scores for daily tasks (p=>0.15). Reverse total shoulder arthroplasty was an independent predictor for decreased ability to tuck in a shirt (P<0.001) and put on a coat (P=0.03) compared to anatomic TSA.
