The effect of different graft tensioning in anterior cruciate ligament reconstruction: a prospective randomized study.
A prospective study was performed to establish the influence on stability of tensioning the graft after anterior cruciate ligament reconstruction with a bone-patellar tendon-bone graft. There were 38 consecutive patients randomly divided into two groups; in the first group (19 patients) the graft was tensioned at 20 N, and in the second group the tension was 40 N. Evaluation included Lysholm scores, instrumented Lachman tests, IKDC level, and lateral radiographs to measure the tibia position versus the femur. One year after surgery we did not find any significant difference between the two groups. We conclude that the importance of graft tensioning has yet to be established in the clinical situation. Based on our results, graft tension of 20 N seems to be sufficient, without the risk of overconstraining the knee joint.
