Assessment of repair integrity and clinical outcome after arthroscopic repair of rotator cuff tears in double-row suture-bridge technique with the use of a new knotless suture-anchor system.
The first treated 25 patients with arthroscopic rotator cuff repair in the suture-bridge technique using a novel knotless anchor and chain-link suture system were evaluated. Patients with isolated full-thickness supraspinatus tears were selected. They were followed clinically with functional scores (Constant score, ASES index), visual analog scale (VAS), and instrumentally with Isobex digital strength analyzer preoperatively, at 6 and 14 months postoperatively. The repair integrity was evaluated with MRI at an average of 14 months postoperatively.
Significant improvement of pain, strength, range of motion, and functional scores occurred (P < 0.05). There was a re-tear rate of 20%. The subjective parameters (VAS and ASES Index) showed non-significant (n.s.) differences between the re-tear and intact repair groups, whereas the objective parameters (Constant score, muscle power and active ROM) showed significant differences between both groups (P < 0.05).
The functional outcome has improved significantly with this new knotless anchor-chain system and was more superior in shoulders with intact repair, whereas the resulted repair integrity was not better than other types of double-row repair techniques mentioned in the recent literature. However, this early report of the novel technique may show limited power for comparison due to the relatively small sample size.
评估使用新型无结缝线锚钉和链式缝线系统的关节镜下双排缝线桥技术修复肩袖撕裂的修复完整性和临床结果。
对 25 例采用新型无结锚钉和链式缝线系统行关节镜下缝线桥技术修复肩袖撕裂的患者进行评估。入选患者均为单纯全层冈上肌腱撕裂。采用 Constant 评分、ASES 指数、视觉模拟评分(VAS)和 Isobex 数字力量分析器对患者进行术前、术后 6 个月和 14 个月的临床随访,评估修复完整性。MRI 评估在术后平均 14 个月进行。
疼痛、力量、活动度和功能评分均显著改善(P < 0.05)。再撕裂率为 20%。再撕裂组和完整修复组的主观参数(VAS 和 ASES 指数)差异无统计学意义(n.s.),而客观参数(Constant 评分、肌肉力量和主动活动度)差异有统计学意义(P < 0.05)。
与其他类型的双排修复技术相比,这种新型无结锚钉-链式缝线系统的功能结果显著改善,在完整修复的肩中更为优越。然而,由于样本量较小,这种新技术的早期报告可能由于比较受限而显示出有限的效力。
