Due to the rotator cuff retear after being surgically repaired, some strategies have been developed. The authors verified that the possibility of polyetheretherketone (PEEK) vented anchors promoted a better clinical and healing process than PEEK solid anchors.
A prospective and randomized study was designed with 38 patients treated with PEEK anchors, 18 of whom with vented anchors and 20 with solid ones. Demographic, clinical and radiologic data were collected before and during surgery (time 0) and at 12 months of follow-up.
In the final follow-up (12 months), there was no difference in the visual analogic scale (VAS) scale between groups (1.7 points vs 1.9 points; p = 0.731), neither in the DASH score (34.2 points vs 23.9 points; p = 0.268), nor in absolute Constant score (76.9 points vs 77.3 points; p = 0.910). In MRI, 10 patients had their cuff tear healed in the vented group and 15 in the solid group (p = 0.173).
The new designed vented anchors do not add any advantage when compared to solids ones, at least within the first year after surgery.
由于肩袖修复术后出现再撕裂，已制定了一些策略。作者证实，与聚醚醚酮（PEEK）实心锚钉相比，PEEK带孔锚钉在促进更好的临床效果和愈合过程方面具有更大的可能性。
设计了一项前瞻性随机研究，38例患者接受了PEEK锚钉治疗，其中18例使用带孔锚钉，20例使用实心锚钉。在手术前、手术期间（时间0）以及随访12个月时收集人口统计学、临床和放射学数据。
在最终随访（12个月）时，两组之间的视觉模拟评分量表（VAS）评分无差异（1.7分对1.9分；p = 0.731），上肢功能障碍评分（DASH）（34.2分对23.9分；p = 0.268）以及绝对Constant评分（76.9分对77.3分；p = 0.910）也无差异。在磁共振成像（MRI）检查中，带孔组有10例患者的肩袖撕裂愈合，实心组有15例（p = 0.173）。
至少在手术后的第一年内，新设计的带孔锚钉与实心锚钉相比没有任何优势。
