Anatomic double-bundle anterior cruciate ligament reconstruction leaving hamstrings tibial insertion intact:...

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Biomechanical Engineering

Background:

• Anterior cruciate ligament (ACL) injuries are common in athletes.
• Traditional ACL reconstruction techniques have limitations.
• Improving graft healing and long-term stability is crucial.

Purpose of the Study:

• To describe a novel anatomic, double-bundle arthroscopic ACL reconstruction technique.
• To evaluate the use of specific surgical tools and graft fixation methods.
• To explore the potential benefits of preserving graft tibial insertion.

Main Methods:

• Arthroscopic technique utilizing autologous gracilis and semitendinosus tendons.
• Second-generation retrograde femoral drills and adjustable suspensory fixation.
• Standard tibial drills and low-profile tibial staples.
• Harvesting tendons with preserved tibial insertion.

Main Results:

• Graft length is customizable to individual knee anatomy.
• Graft tension can be adjusted post-fixation.
• Preservation of tibial insertion may promote neoligamentization via tenodesis.

Conclusions:

• This technique offers precise graft sizing and adjustable tensioning.
• Preserving tendon tibial insertion is a novel approach for potential enhanced graft incorporation.
• The described method aims to improve outcomes in ACL reconstruction.
