Technical Aspect | Advantages | Neutral | Disadvantages |
---|---|---|---|
Flat “ribbon-like” graft | Recreates native fiber arrangement with either a quadriceps tendon or a hamstring graft. | No difference in graft size (cross-sectional area). | Learning curve for graft preparation. |
Rectangular femoral tunnel | Recreates anatomic ACL origin. Reduces the distance for blood vessel ingrowth. |
Guidewire location is the same. | More surgical steps in tunnel preparation. |
C-shaped tibial tunnel | Recreates anatomic “C”-shaped insertion. Preserves the anterior tibial insertion of the lateral meniscus. Reduces the distance for blood vessel ingrowth. |
– | More steps in tunnel preparation. |
Graft insertion | Graft orientation during insertion is achieved with simply extending the knee. | – | Exact graft preparation is required to avoid problems with insertion due to high frictional resistance. |
ACL, anterior cruciate ligament.
