Multicenter retrospective study of 555 shoulders examining how supraspinatus tendon tears and rotator cuff muscle fatty degeneration — graded by Goutallier CT staging — affect Constant-Murley scores, range of motion, satisfaction, and radiographic outcomes after shoulder arthroplasty for primary glenohumeral osteoarthritis at mean 43-month follow-up.
When evaluating a patient with primary glenohumeral OA for arthroplasty, don't let a supraspinatus tear on imaging change your operative plan — but scrutinize the infraspinatus muscle belly on CT for Goutallier fatty degeneration, because stage 2 or higher predicts meaningfully worse external rotation and overall function regardless of whether you repair the cuff.
