Labral Pull-Through Technique for Arthroscopic Labral Reconstruction of the Hip
Video Journal of Sports Medicine(2023)
摘要
Background: The goal of hip labral reconstruction is to restore the suction seal, requiring the labral graft to be precisely secured along the acetabular rim. When performed arthroscopically, controlling the graft as it is suspended in the hip joint between 2 cannulas can be challenging, making fixation in the optimal position to restore the suction seal difficult to achieve. Indications: Labral reconstruction/augmentation is indicated for patients with a deficient/dysfunctional labrum when repair alone cannot restore/maintain the suction seal. Technique Description: Following diagnostic arthroscopy, debridement, and measurement of the labral deficiency (30 mm), 70 mm tibialis anterior allograft was tubularized with a whipstitch and prepared with long suture tails at both ends and a single mattress stitch placed through the graft at the medial end. Holes for the anchors were pre-drilled. Viewing from the anterolateral portal, the graft was introduced down a sled through the modified anterior portal, pulled through the joint, and guided into the posterolateral portal cannula via instrumentation through the distal anterolateral accessory portal. With initial fixation achieved medially with the mattress stitch, directing the graft into position while achieving optimal coverage of the deficient area was facilitated by the excess graft length pulled into the posterolateral portal cannula. Results: Labral reconstruction can restore the suction seal of the hip joint when repair alone is not sufficient. Comparative studies with matched repair cohorts have demonstrated comparable survivorship and patient-reported outcomes between groups, with similar rates of patient acceptable symptomatic state and minimal clinically important difference between groups, and similar rates of return to sport in high-level athletes. Recent systematic reviews have largely corroborated these findings. Discussion/Conclusions: Arthroscopic labral reconstruction is an effective treatment option when repair alone cannot restore the suction seal when the graft is secured in an optimal position, but controlling the graft during passage and fixation while achieving a final length spanning the segmental deficiency in continuity with native tissue at both ends can present technical challenges. The labral pull-through technique greatly facilitates this process.
