This study (1) compared clinical outcomes and tissue healing between delaminated and nondelaminated rotator tear after repair and (2) evaluated clinical results according to the degree of tissue healing.Materials and methodsNinety-five patients who underwent arthroscopic rotator cuff repair were divided into delaminated tear and nondelaminated tear groups. Tissue healing was evaluated using computed tomography arthrogram and classified into anatomic healing, partially healed defect, and retear. The American Shoulder and Elbow Surgeons Shoulder Assessment score and Constant score were evaluated to quantify the clinical results.ResultsThe mean American Shoulder and Elbow Surgeons and Constant scores at final follow-up were 82 ± 10 and 77 ± 7 in the delaminated tear group and 83 ± 12 and 75 ± 9 in the nondelaminated tear group, respectively. There was no statistical difference (P = .13 and P = .17, respectively). Anatomic healing was most common in both groups. A partially healed defect was the second most common in the delaminated tear group (20 [40.8%]) and retear was the second most common in the nondelaminated tear group (11 [23.9%]; P = .04). Clinical scores showed a statistically significant difference according to tissue healing.ConclusionsA delaminated tear showed no difference in the clinical outcome but a difference in tissue healing compared with a non-delaminated tear. Although clinical scores showed a difference according to tissue healing, a higher partially healing defect and lower retear compared with a nondelaminated tear may imply that a delaminated tear may not be a poor prognostic factor after repair.
