Abstract：
UNASSIGNED: Even though arthroscopic rotator cuff repair is recognized as a standard treatment option, the risk of postoperative retear is a major concern.
UNASSIGNED: To evaluate the effect of porcine-derived absorbable patch-type atelocollagen during arthroscopic rotator cuff repair.
UNASSIGNED: Randomized controlled trial; Level of evidence, 1.
UNASSIGNED: A total of 64 patients with rotator cuff tears diagnosed on magnetic resonance imaging (MRI) were enrolled prospectively from November 2020 to December 2021. Both groups had repairs using the suture bridge technique. For the atelocollagen group, before securing the lateral anchors, we inserted porcine-derived absorbable patch-type atelocollagen between the footprint and the tendon. On postoperative day 2, the patients underwent MRI to confirm containment of the patch-type atelocollagen. At 6 months and 1 year postoperatively, the signal intensity of the repaired tendon was assessed using MRI. Patients were evaluated using the Constant score as the primary outcome, along with the visual analog scale for pain; range of motion; American Shoulder and Elbow Surgeons score; University of California, Los Angeles, score; and Korean Shoulder Score preoperatively and at 2, 3, 6, and 12 months postoperatively.
UNASSIGNED: No significant changes in the Constant score as primary outcome, pain or other functional scores, and range of motion were observed between the groups at 1 year postoperatively. The patch-type atelocollagen was confirmed to be contained by the time-zero MRI scan taken 2 days postoperatively. Among the 55 patients included in final analysis, 12 retear cases were recorded (21.8% retear rate). A significantly lower retear rate was found in the atelocollagen group, as 3 cases were observed in this group (10.3%) and 9 cases were observed in the conventional repair group (34.6%) (P = .048).
UNASSIGNED: The Constant score was not different between the groups. The retear rate after rotator cuff repair was significantly lower in the group that received porcine-derived absorbable patch-type atelocollagen compared with in the conventional group.

摘要：
■即使关节镜肩袖修复被认为是一种标准治疗选择，术后撕裂的风险是一个主要问题。
■评价猪来源的可吸收斑片型去骨胶原在关节镜肩袖修复中的作用。
■随机对照试验；证据水平，1.
■从2020年11月至2021年12月，前瞻性纳入了64例经磁共振成像（MRI）诊断的肩袖撕裂患者。两组均使用缝合桥技术进行了修复。对于去胶原组，在固定侧锚之前，我们在足印和肌腱之间插入了猪来源的可吸收斑贴型去端胶.术后第2天，患者接受MRI检查以确认斑块型骨胶原的容纳。术后6个月和1年，使用MRI评估修复肌腱的信号强度.使用Constant评分作为主要结果对患者进行评估，以及疼痛的视觉模拟量表；活动范围；美国肩肘外科医生评分；加州大学，洛杉矶,评分；以及术前和术后2、3、6和12个月的韩国肩关节评分。
■作为主要结果的Constant评分没有显著变化，疼痛或其他功能评分，术后1年观察组间的活动范围。术后2天进行的零时间MRI扫描证实了包含贴片型骨胶原。在最终分析的55名患者中，记录了12例再撕裂（21.8％的再撕裂率）。在前胶原组中发现了明显较低的再撕裂率，本组3例（10.3％），常规修复组9例（34.6％）（P=.048）。
■两组之间的Constant评分没有差异。与常规组相比，接受猪源可吸收斑片型前胶原的肩袖修复后的再撕裂率显着降低。
