Schematic drawing of the experimentalsetup.

A: Experimental setup, B: Measurementsystem | 1: stopper, 2: fallingweight, 3: pulley, 4: steel rope, 5: force transducer, 6:force plate, 7: visual cover, 8: linear potentiometer.Arrows indicate the direction of the force. Posterior-anteriortibial translation was assessed by two linear potentiometers (8)placed on the patella and the tibial tuberosity. A force transducer (5)was used to measure the force transmitted to the shank.
