This retrospective study of prospectively collected data establishes clinically significant outcome thresholds for the single-question SANE score after total and reverse shoulder arthroplasty. It asks whether SANE thresholds for MCID, SCB, and PASS correlate with achievement on the longer ASES and Constant scores.
When a patient is one year out from shoulder arthroplasty, you can gauge meaningful improvement with a single question rather than a multi-item form. Memorize the SANE thresholds: a 28.8-point rise is the MCID, 50.2 is the SCB, and a postoperative score of 75.5 is the PASS.
The study's core teaching point is that raw SANE values correlate only weakly with ASES and Constant, so you cannot convert one score to another. What transfers is threshold achievement, meaning a patient who clears SANE SCB usually clears it on legacy scores too. Be cautious with ASES MCID, where SANE agreement was not significant.
One appraisal caveat: thresholds shift with the anchor question used, so these numbers apply to satisfaction and activity anchors, not global Likert anchors from other papers. The main limitation is a single-center retrospective cohort of 207 with only 61.7% compliance, which introduces selection bias.
