Summary
This study introduces a novel double-bundle anterior cruciate ligament reconstruction technique using hamstring grafts. The procedure offers precise graft placement and secure fixation with minimal hardware.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Anterior cruciate ligament (ACL) injuries are common, often requiring surgical reconstruction.
- Double-bundle ACL reconstruction aims to restore native knee biomechanics more effectively than single-bundle techniques.
- Current techniques face challenges in graft placement accuracy and fixation security.
Purpose of the Study:
- To describe an original double-bundle anterior cruciate ligament reconstruction technique.
- To detail the use of hamstring tendon grafts with preserved tibial osseous insertion.
- To present a simplified and precise femoral drilling method and evaluate graft fixation.
Main Methods:
- Hamstring tendon autografts were utilized for reconstruction.
- Two distinct tibial tunnels were created, preserving tibial osseous insertion.
- A simplified outside-in, double-tunnel femoral drilling technique was employed.
- Graft fixation was achieved using two interference screws.
Main Results:
- The described technique allows for double-bundle reconstruction using hamstring grafts.
- Tibial osseous insertion is maintained throughout the procedure.
- A precise and simplified femoral drilling method is utilized.
- Secure graft fixation is achieved with only two interference screws.
Conclusions:
- This novel technique provides a reproducible method for double-bundle ACL reconstruction.
- The procedure ensures accurate graft placement and robust fixation.
- It offers a potentially advantageous option for restoring knee stability and function.
