Comparing radiologic bone ingrowth and the clinical outcomes of an open-construct (PEEK) (polyether ether ketone) suture anchor with those of a bio-composite suture anchor (glycolic polylactic acid anchors, beta-tricalcium phosphate and calcium sulphate) in patients with arthroscopic rotator cuff repair.
From August 2017 to January 2019, 33 patients of both sexes, aged between 44 and 78 years underwent arthroscopic rotator cuff repair for tears considered repairable with an extension not exceeding4 cm. The bioabsorbable anchors used comprised glycolic polylactic acid/beta-tricalcium phosphate/ calcium sulphate, and the non-absorbable anchors in polyetheretherketone (PEEK). All patients underwent MRI evaluation at 12 months postoperatively to determine complications and identify any re-tear.
Clinical scores showed an improvement from both clinical and functional point of view. There were no statistically significant changes compared to the physical examination. On radiographs, mobilizations, anchor pull-outs or other complications did not occur in each group.
Shoulder function improved after complete repair of the rotator cuff and similar clinical results were achieved regardless of the material and shape of the suture anchor. The bioabsorbable anchors in innovative open architecture material seem to have results comparable to peek anchors. Unfortunately, further studies are needed to define the advantages in using one material compared to the other. (www.actabiomedica.it).
比较开放式结构（PEEK）（聚醚醚酮）缝线锚钉与生物复合材料缝线锚钉（聚乙醇酸/β-磷酸三钙/硫酸钙）在关节镜肩袖修复患者中的影像学骨内生长和临床结果。
2017 年 8 月至 2019 年 1 月，33 名男女患者，年龄 44-78 岁，均接受关节镜肩袖撕裂修复术，撕裂程度被认为可修复，且延长不超过 4cm。使用的生物可吸收锚钉为聚乙醇酸/β-磷酸三钙/硫酸钙，不可吸收锚钉为聚醚醚酮（PEEK）。所有患者均在术后 12 个月行 MRI 评估，以确定并发症并确定任何再撕裂。
临床评分显示从临床和功能角度均有改善。与体格检查相比，无统计学意义的变化。在影像学上，各组均未发生移动、锚钉拔出或其他并发症。
肩袖完全修复后，肩部功能得到改善，无论缝线锚钉的材料和形状如何，均获得相似的临床结果。创新开放式结构材料的生物可吸收锚钉似乎具有与 PEEK 锚钉相当的结果。不幸的是，需要进一步的研究来确定使用一种材料相对于另一种材料的优势。（www.actabiomedica.it）。
