Preoperative tear size was the best predictor of overall postoperative tear rate 6 months after a rotator cuff repair, according to this study.
“Tear size was the best intraoperative predictor of repair integrity after rotator cuff repair, with tears less than 2 cm2 twice as likely to heal than tears greater than 6 cm2,” Xiao L. Wu, MBBS, and colleagues stated in the study abstract.
Preoperative tears ≤ 2 cm2 were the least likely to cause retears at 10%, according to the abstract. Between 2 cm2 and 4 cm2, the risk of retear was 16% and between 4 and 6 cm2, the risk was 31%. A tear greater than 8 cm2 represented a 57% risk for retear, according to the abstract.
Other correlations with retears included repair quality, tendon mobility and tendon quality, but these associations are not as strong, according to the abstract.
