Internal rotation (IR) force measurements and IR ROM have been made and compared to the healthy contralateral side. Then the footprint of the SSC was routinely investigated by arthroscopy with standardized measurement of the bony footprint lesion. The partial tears were classified according to the mediolateral and craniocaudal extension of the rupture in the transverse and coronal plane, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Partial SSC tears could be classified into split lesions (type 1, <jats:italic>n<\/jats:italic>\u2009=\u200911) and 3 further groups depending on the mediolateral peeled\u2010off length of the bony footprint (type 2:\u2009&lt;\u200910\u00a0mm, <jats:italic>n<\/jats:italic>\u2009=\u200920; type 3: 10\u201315\u00a0mm, <jats:italic>n<\/jats:italic>\u2009=\u200910; type 4:\u2009&gt;\u200915\u00a0mm, <jats:italic>n<\/jats:italic>\u2009=\u20099). Type 2\u20134 could be further divided depending on the craniocaudal peeled\u2010off length of the bony footprint (group A:\u2009&lt;\u200910\u00a0mm, group B: 10\u201315\u00a0mm, group C:\u2009&gt;\u200915\u00a0mm). Significantly decreased IR strength was shown for types 2\u20134 (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05) but not for split lesions as compared to healthy side. Types 1\u20134 showed significant decreased active IR ROM and all except type 3 (n.s.) which showed decreased passive IR ROM compared to the healthy side (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>We present a novel classification for partial SSC tears for a more detailed and reproducible description.
