A prospectively randomized double-blind study on the effect of initial graft tension on knee stability after anterior cruciate ligament reconstruction.

Background: No consensus exists on the amount of tension that should be applied to anterior cruciate ligament grafts to best facilitate graft incorporation and re-create normal knee mechanics.

Hypothesis: Differences in initial graft tension will affect postoperative knee stability.

Study Design: Prospective, randomized, double-blind clinical trial.
