Die laterale extraartikuläre Tenodese in der modifizierten Ellison-Technik bei Kindern
摘要
Lateral extra-articular tenodesis (LET) and anterolateral ligament (ALL) reconstruction have become well-established adjunctive procedures to anterior cruciate ligament (ACL) reconstruction and are currently performed using a variety of surgical techniques. Compared with other LET procedures, the modified Ellison technique offers several important advantages, particularly in pediatric and adolescent patients. In addition to its distance from the physes, resulting in a low risk of growth plate injury, the technique eliminates the risk of tunnel convergence with the ACL graft. Furthermore, biomechanical studies have demonstrated less rotational overconstraint, particularly with respect to internal tibial rotation, compared with the modified Lemaire technique. The modified Ellison tenodesis is performed through a lateral approach over the iliotibial band (ITB) between Gerdy’s tubercle and the lateral femoral epicondyle. Following exposure of the ITB, an approximately 10-mm-wide strip is detached from Gerdy’s tubercle and mobilized proximally in line with its fiber orientation to a point just posterior to the lateral epicondyle. The strip is then passed deep to the lateral collateral ligament (LCL) and reinserted at Gerdy’s tubercle. Several fixation methods have been described; however, in clinical practice, the use of suture anchors in an onlay fashion has proven to be a reliable and effective technique. Subsequently, the distal ITB is adapted to the Ellison graft, and the proximal split in the ITB is closed over the reconstruction. Postoperative rehabilitation following ACL reconstruction does not require specific adaptation or modification due to the addition of an LET procedure.
