One hundred Newtons was decided on as the maximum force following measurements in theatre showing a force of approximately 75N were applied to a hamstring ACL graft at the time of fixation in the tibial tunnel. The DVRT’s allowed accurate assessment of the Load/Displacement of each tendon in the construct to be assessed. Repeatability experiments on the DVRT’s were performed. Ten specimens were prepared which were all tested in the different suturing configurations. Each test was repeated three times on each construct.
