<p>A device (10) for measurement of laxity of the knee comprises a thigh support (12) and a foot support (13) so arranged that the leg of the patient will be bent at the knee when the patient's thigh is resting in the thigh support (12) and his foot is strapped to the foot rest (13). A potentiometer (26) measures movement of the tibial tuberosity of the patient's leg relative to the patella, and a strain gauge mounted on plate (15) measures the force applied by a patient seeking to straighten the leg such as by tensioning the quadriceps muscle. A computer (9) plots and displays a graph (8) or other output of the force applied against the relative movement between the tibial tuberosity and the patella.</p> |
