The purpose of this study was to clarify the preoperative clinical features and MRI findings that related to reruptures after repaired massive and large rotator cuff tears. There were 21 patients who underwent the primary repair for massive and large rotator cuff tears from April, 1996 to April, 2005. The integrity of rotator cuff was evaluated on MRI after surgery in 16 patients. According to the integrity of rotator cuff, the patients were divided into the repaired group and re-ruptured group. Preoperative clinical features and MRI findings were compared between the 2 groups. There were 7 patients in the repaired group and 9 in re-ruptured group. There were significant differences in active range of abduction of the shoulder (114°: 64°) and postoperative JOA score (95: 73) between the 2 groups. The incidence of preoperative active abduction under 90 o in re-ruptured group (8 cases) was also significantly higher than those in the repaired group (3 cases). Regarding to muscle fatty degeneration, Goutallier stage of the supraspinatus was 0 or 1 in all cases of the repaired group and 2 or 3 in 5 cases of re-ruptured group. That of infraspinatus was also 1 or 2 in all cases in the repaired group and 3 or 4 in 4 cases in re-ruptured group. In conclusion, if a patient with large or massive rotator cuff tear has a poor range of active abduction of the shoulder and high intensity in the supraspinatus and the infraspinatus on MRI, the primary repair might result in re-rupture of the rotator cuff.
