Summary
The functional reconstruction of the anterior cruciate ligament (ACL) requires the following:
-
1.
Minimal length change, preferably less than 5 mm.
-
2.
Prevention of length change conducive to anterolateral rotatory instability (ALRI), namely 5.7 mm between the knee flexion of 0° and 30°.
-
3.
The over-the-top (OTT) pattern with its superior stability in extension.
-
4.
Proximal placement of the patellar tendon in the femoral tunnel to produce an OTT graft tracking pattern.
