The importance of the acetabular labrum has been well documented for the function and overall health of the hip joint. Several biomechanical studies have shown the sealing effect of the acetabular labrum. In the past decade, labral repair procedures have gained increased attention, with the literature suggesting that the outcomes after hip arthroscopy are directly related to labral preservation. However, a primary labral repair can be challenging in cases of hypoplastic, ossified, or complex and irreparable labral tears in which there is insufficient tissue to perform a primary repair. For these cases, labral reconstruction becomes a viable option with good outcomes at short-term and midterm follow-up. A subset of these patients may show viable remnants of the labral circumferential fibers but, because of the low tissue volume, these remnant fibers are unable to maintain the suction seal. In this situation, a labral augmentation may be a viable alternative to labral reconstruction while preserving as much native labral tissue as possible. The purpose of this Technical Note is to describe an arthroscopic hip labral augmentation technique using iliotibial band autograft or allograft.
髋臼盂唇对髋关节功能和整体健康的重要性已得到充分证明。多项生物力学研究表明了髋臼盂唇的密封作用。在过去十年中，盂唇修复手术越来越受到关注，文献表明髋关节镜检查后的结果与盂唇保留直接相关。然而，在髋臼发育不全、盂唇骨化或复杂且无法修复的盂唇撕裂病例中，进行初次盂唇修复可能具有挑战性，因为没有足够的组织进行初次修复。对于这些病例，盂唇重建成为一种可行的选择，在短期和中期随访中效果良好。这些患者中有一部分可能显示出盂唇圆周纤维的存活残余部分，但由于组织量少，这些残余纤维无法维持吸力密封。在这种情况下，盂唇增强术可能是盂唇重建的一种可行替代方法，同时尽可能保留更多的天然盂唇组织。本技术说明的目的是描述一种使用自体或异体髂胫束的关节镜下髋关节盂唇增强技术。
