Summary
Anatomic double-bundle anterior cruciate ligament (ACL) reconstruction provides stable, pain-free knees with outcomes comparable to the native ACL. This technique precisely restores knee function and kinematics.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Biomechanical engineering
Background:
- Anterior cruciate ligament (ACL) injuries are common, often requiring surgical reconstruction.
- Restoring native knee function and biomechanics is crucial for long-term outcomes.
- Anatomic double-bundle reconstruction aims for precise graft placement within the ACL footprint.
Purpose of the Study:
- To evaluate early outcomes of anatomic double-bundle ACL reconstruction.
- To compare reconstructed ACLs with contralateral native ACLs using imaging and clinical scores.
- To assess graft placement accuracy and knee kinematics restoration.
Main Methods:
- Retrospective review of 110 patients undergoing arthroscopic ACL reconstruction (minimum 3-year follow-up).
- Clinical evaluation including Lysholm scores.
- Postoperative MRI and CT scans for 63 patients to assess graft placement and knee angles.
Main Results:
- Reconstructed knees were stable and pain-free with a mean Lysholm score of 95.54.
- CT/MRI confirmed accurate graft centering within the native ACL footprint.
- Sagittal and Blumensaat line angles of reconstructed ACLs closely matched contralateral native ACLs (P > 0.05).
Conclusions:
- Anatomic double-bundle ACL reconstruction allows precise graft placement.
- This technique effectively restores knee kinematics and function.
- Outcomes suggest successful restoration of native ACL biomechanics.
