Rotator cuff repairs with all-suture tape anchors: no difference in outcomes between with or without all-suture tape anchors

Abstract

PurposeThis study aimed at comparing the outcomes of medium‐ to large‐sized rotator cuff repairs performed using the suture bridge technique either with or without tape‐like sutures, and single row techniques with conventional sutures. MethodsA total of 135 eligible patients with medium to large rotator cuff tears were identified and analyzed retrospectively, from 2017 to 2019. Only repairs using all‐suture anchors were included in the study. Patients were divided into the following three groups: single‐row (SR) repair (N = 50), standard double‐row suture bridge (DRSB) repair with conventional sutures (N = 35), and DRSB with tape‐like sutures (N = 50). The average postoperative follow‐up period was 26.3 ± 9.8 months (range, 18–37). ResultsDRSB with tapes had the highest re‐tear rate of 16% (8/50), but there was no significant difference with the re‐tear rates observed in SR (8%, 4/50) and DRSB with conventional sutures (11.4%, 4/35) (n.s.). DRSB with tapes demonstrated higher rate of type 2 re‐tears (10%) compared to type 1 re‐tears (6%), but the other two groups showed either similar or higher rates of type 1 re‐tears compared to that of type 2. Post‐operative functional scores of the three groups improved significantly (all p < 0.05), but the differences between the groups were not statistically significant. ConclusionsNo clinical difference in functional outcomes and re‐tear rates were observed in DRSB with tapes when compared with SR and DRSB using the conventional sutures. Tape‐like DRSB suture which was expected to be superior by its biomechanical advantage was clinically non‐superior to conventional DRSB suture. There were no significant differences in VAS scores and UCLA scores. Level of evidenceLevel III.
