This study was conducted to measure the tension of torn cuff during arthroscopic rotator cuff repair (ARCR) and to evaluate the short-term postoperative results. 12 men and 8 women with complete rotator cuff tear were included in this study. Their mean age was 60.7 years old. The mean follow-up period was 10.3 months. All patients underwent ARCR using the dual-row fixation technique. The tension of torn cuff was measured with a tension meter during operation. The postoperative MRI was performed at six months after the operation. The short-term clinical results were evaluated with the JOA score and postoperative MRIs. The mean tension of torn cuff was 2.46kg (1.7 to 4.8kg). The tension of small, medium and large tear was 1.87kg, 2.32kg and 3.56kg, respectively. The average JOA score was improved from 61.6 to 90.5 points postoperatively. However, the postoperative MRI showed 3 cases of re-torn cuff; 1 case of medium and 2 cases of large tear. We believe that to decrease the tension of the cuff is one of the important factors to improve the postoperative cuff integrity. This study indicated that the rate of postoperative re-torn cuffs becomes high when the tension of cuff during ARCR is high.
