Summary
This study introduces a novel anterior cruciate ligament (ACL) reconstruction technique preserving hamstring tendon neurovascular supply. The new method enhances graft healing and proprioception compared to traditional hamstring tendon ACL surgeries.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomedical Engineering
Background:
- Current anterior cruciate ligament (ACL) reconstruction techniques using hamstring tendons often involve detaching the tibial insertion.
- This detachment can damage the tendons' neurovascular supply, potentially leading to reduced graft proprioception and impaired healing (ligamentization).
Purpose of the Study:
- To describe a novel surgical technique for anatomical single-bundle ACL reconstruction.
- To utilize distally inserted doubled hamstring tendons while preserving their neurovascular supply.
Main Methods:
- A new surgical technique for ACL reconstruction is detailed.
- This method employs distally inserted doubled hamstring tendons.
- Fixation is achieved at the femoral level using a second-generation cortical suspensory device.
Main Results:
- The described technique allows for anatomical single-bundle ACL reconstruction.
- It preserves the neurovascular supply to the hamstring tendons by avoiding tibial insertion detachment.
- This is expected to improve graft ligamentization and residual proprioceptivity.
Conclusions:
- The novel technique offers an alternative for ACL reconstruction using hamstring tendons.
- It aims to improve graft outcomes by preserving tendon neurovascularity.
- This approach may lead to better functional recovery and long-term graft success.
