All studies were reviewed independently by two musculoskeletal radiologists to assess for joint effusion, periarticular collection, and characterization of associated rotator cuff tears. Tendon tears were assessed with respect to (1) thickness: low grade (&lt;50% thickness), high grade (&gt;50% thickness), full thickness; (2) morphology (focal vs. diffuse) and location (insertion vs. critical zone). Inter\u2010reader agreements were determined using Cohen's kappa test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Ninety\u2010seven studies were performed in 72 patients following TSA, RTSA, or hemiarthroplasty. Thirty\u2010seven exams were solely for diagnostic purposes, and 59 were for guiding joint or periarticular collection aspiration. Twenty\u2010eight studies assessed the cuff tendons post TSA. The mean time between surgery and US examination was 29.2\u2009months. Complete or high\u2010grade tears were identified in 8\/28 (28.6%) diagnostic exams. The most commonly torn tendon among TSA patients was the subscapularis, with 13\/28 (46.4%) demonstrating at least partial tearing. Inter\u2010reader agreement was excellent for presence of effusion (<jats:italic>k<\/jats:italic>\u00a0=\u00a00.79, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) and periarticular collection (<jats:italic>k<\/jats:italic>\u00a0=\u00a00.87, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), and excellent agreement for presence of subscapularis tear (<jats:italic>k<\/jats:italic>\u00a0=\u00a00.78, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001), with fair agreement for assessment of supraspinatus (<jats:italic>k<\/jats:italic>\u00a0=\u00a00.66, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) and infraspinatus (<jats:italic>k<\/jats:italic>\u00a0=\u00a00.60, <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001) tears.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The most commonly torn tendon following anatomic TSA identified by US was the subscapularis, which was torn or deficient in 46.4% of cases.
