Injury to this structure may lead to the presence of residual pivot shift in some reconstructions of the anterior cruciate ligament.  The behavior of the length of this structure and its tension during range of motion has not been established and is essential when planning reconstruction.


 Ten unpaired cadavers were dissected.  Computed tomography scans were performed on the dissected parts under extension and 30°, 60°, and 90° of flexion; measurements of the distance between the 2 markers were taken at all mentioned degrees of flexion.  Its mean length at full extension and at 30°, 60°, and 90° of flexion was 37.9 ± 5.3, 39.3 ± 5.4, 40.9 ± 5.4, and 44.1 ± 6.4 mm, respectively.  Knowledge of ALL behavior during the range of motion of the knee will allow for fixation (during its reconstruction) to be performed with a higher or lower tension, depending on the chosen degree of flexion.
