Editorial Commentary: Irreparable, Symptomatic, Hip Labral Tears Should Be Reconstructed in Patients without Osteoarthritis. However, Comparison of the Two, as Well as Allograft versus Autograft Reconstruction, Is Challenging.

Abstract

Hip acetabular labrum plays a chondroprotective role by maintaining stability, providing a suction seal, and contributing to load distribution. In symptomatic patients without osteoarthritis, arthroscopic labral repair has strong clinical and biomechanical data to support its use. For irreparable tears, the labrum should be reconstructed. Biomechanically, labral reconstruction does not demonstrate superiority when compared to labral repair or the intact native labrum state. However, it is superior to labral excision. One challenge in making these comparisons is the heterogeneity in surgical technique. Labral reconstruction techniques can vary significantly. In terms of reconstruction, allograft offers the advantage of no donor site morbidity, but availability, costs, and risks must be considered. Autograft use is limited by donor site morbidity and increased operative time. Direct comparisons again show no clear evidence to suggest superiority of one over the other.
