Abstract:
Classic techniques in arthroscopic hip labral repair use circumferential or intrasubstance suture secured with anchors typically placed behind the labrum (capsular side). The primary goal of labral repair is to re-establish the hip suction seal and is often achieved via fixation techniques that invert viable labral tissue to restore or improve contact with the femoral head. Many repair techniques use only 1 suture limb either passed circumferentially around the labrum or passed in an intrasubstance manner, resulting in smaller purchase of labral tissue and lack of a strong inverting vector. In some cases, this may evert the labral tissue, compromising the suction seal. We describe a technique in which both suture limbs are passed in a mattress, figure-of-8 configuration, through the labral tissue, and tied on the capsular side to yield an inverting, double-limb repair. Therefore, each anchor results in a wider, more impactful repair footprint while reliably inverting the labral tissue.
