Lateral Extra-articular Tenodesis Utilizing Modified Ellison Technique With Knotless Anchor Fixation

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Anterior cruciate ligament (ACL) reconstruction is a common orthopedic procedure.
• Graft failure remains a significant concern, necessitating augmentation techniques.
• Lateral extra-articular tenodesis (LET) has shown promise in reducing ACL graft failure.

Purpose of the Study:

• To describe a preferred technique for lateral extra-articular tenodesis (LET) augmenting ACL reconstruction.
• To highlight the advantages of the modified Ellison technique with knotless anchors.
• To demonstrate a reproducible and efficient method for enhancing ACL graft stability.

Main Methods:

• Utilized the modified Ellison technique for LET.
• Employed both all-suture and hardbody knotless anchors for fixation.
• Integrated LET into standard ACL reconstruction procedures.

Main Results:

• The described technique provides dynamic rotational stability.
• It minimizes the risk of lateral compartment overload.
• Eliminates concerns regarding femoral tunnel convergence.

Conclusions:

• Knotless anchor fixation offers a reproducible and efficient method for LET.
• This approach enhances extra-articular stability in ACL reconstruction.
• The technique does not necessitate alterations to postoperative rehabilitation protocols.
