Establishing minimally important differences for the American Shoulder and Elbow Surgeons score and the Western Ontario Rotator Cuff Index in patients with full-thickness rotator cuff tears

This is the first study to report MIDs for the ASES and WORC in a population of patients with only full-thickness RCTs. This information will directly improve our ability to determine when patients with RCTs are changing in a meaningful manner and accurately power clinical studies using these outcome measures.
