Initial Graft Tension and ACL Surgery

"The amount of tension that is applied to the graft at the time of fixation is being performed with the knee in two different positions. When the knee is at 30 degrees of flexion, the resulting laxity is approximately 2 mm less than the contralateral leg (the High Tension treatment). When the tension is performed with the knee in extension (0 degrees of flexion), the the laxity is equal to that of the contralateral leg (the Low Tension treatment). Both methods are commonly used in clinical practice. The effect it may have on articular cartilage remains unknown."
