Anatomic Double-Bundle Anterior Cruciate Ligament Reconstruction Using Two Hamstring Tendon Autografts With Hybrid...

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Anterior cruciate ligament (ACL) injuries are common, often requiring surgical reconstruction.
• Traditional single-bundle ACL reconstruction may not fully restore native knee anatomy and function.
• Double-bundle ACL reconstruction aims for more anatomical restoration of the ACL footprint.

Purpose of the Study:

• To describe and evaluate a novel hybrid technique for double-bundle ACL reconstruction.
• To assess the anatomical accuracy and rotational stability of this hybrid technique.
• To compare the benefits of hybrid fixation versus traditional methods.

Main Methods:

• A hybrid reconstruction technique combining all-suspensory and partial suspensory/interference fixation was developed.
• The technique focuses on accurate anatomical placement of both bundles on the femoral and tibial sides.
• Graft thickness and footprint coverage were key considerations in the surgical approach.

Main Results:

• The hybrid technique allows for complete coverage of the native ACL footprint on both femoral and tibial sides.
• This method provides enhanced rotational stability compared to some traditional double-bundle techniques.
• Adequate graft thickness ensures comprehensive restoration of the joint's biomechanics.

Conclusions:

• The described hybrid double-bundle ACL reconstruction offers an anatomically accurate approach.
• This technique potentially improves rotational control and restores knee function more effectively.
• It represents a viable alternative for achieving superior outcomes in ACL reconstruction surgery.
