The purpose of this study was to test the strength of a suture capsulorrhaphy repair versus a capsulolabral repair with knotless suture anchors in a cadaveric model with anteroinferior shoulder instability.
Fourteen cadaveric shoulders were tested with either a suture capsulorrhaphy to the intact labrum or a capsulolabral advancement using a knotless suture anchor into the glenoid. Specimens were translated with the shoulder in an abducted, externally rotated position to failure.
The capsulolabral advancement showed a significantly higher load to failure than did the suture capsulorrhaphy group (P = .030).
Capsulolabral advancement with suture anchors may offer greater initial strength when compared with a suture capsulorrhaphy. In the setting of shoulder instability without evidence of a labral tear, the capsulolabral advancement technique may be considered biomechanically superior.
In the setting of shoulder instability due to capsular insufficiency, the capsulolabral advancement may be considered biomechanically superior to a traditional suture capsulorrhaphy.
本研究旨在测试在盂肱前下不稳的尸体模型中，缝线关节囊缝合修复与无结缝线锚钉关节囊-盂唇修复的强度。
14 个尸体肩进行了缝线关节囊缝合修复到完整的盂唇，或用无结缝线锚钉将关节囊-盂唇推进到盂肱关节。标本在肩关节外展和外旋位置下进行翻译直至失效。
关节囊-盂唇推进组的失效负荷明显高于缝线关节囊缝合修复组（P=0.030）。
与缝线关节囊缝合修复相比，缝线锚钉的关节囊-盂唇推进可能提供更大的初始强度。在没有盂唇撕裂证据的肩关节不稳定的情况下，关节囊-盂唇推进技术可能在生物力学上更优越。
在由于囊状不足导致的肩关节不稳定的情况下，与传统的缝线关节囊缝合修复相比，关节囊-盂唇推进可能在生物力学上更优越。
