Beyond that, it is a single-surgeon study using the same appliance in all cases with the uniform diagnosis of osteoarthritis, and presumably, identical physical therapy orders. With that background, it seems that the question should not be: “Is there a difference in outcome between dominant versus nondominant shoulder following total shoulder arthroplasty?” Instead, we should ask: “Why would there be any difference?” The authors go on to suggest that this information could be useful in terms of preoperative “patient counseling concerning the expected outcome.” Is that a good idea?
