Demographic information of the patient population
Figure 1Grashey view of the retraction zones of supraspinatus tears of the rotator cuff, against a normal x-ray of the left shoulder.

Operative findings: zones of retraction and tendon involvement
Post-operative comparison of objective outcomes (ROM in degrees, strength measurements in kg) and functional outcomes (ASES scores, constant scores, and SSV) between Group 1 (maximal medial retraction to the mid-line level of the humeral head (Boileau stage<3) and Group 2 (maximal medial retraction to the glenohumeral joint or greater (Boileau stage≥3). Significance set at P<0.05
Post-operative comparison of the strength (kg) and ASES scores between the operative side and the contralateral side. Significance set at P<0.05)
Retraction stage (Boileau) determined intra-operatively and Goutallier scores from pre-operative MRI correlated with healing based post-operatively with ultrasound. Gray indicates massive tears based on number of complete tendons involved≥2
