Abstract
A surgical aid for joints which allows the positioning of mono-compartment or three-compartment prosthetic components so that the isometry of the capsular-ligament tissues of the knee is maintained during the entire range of motion. Such surgical aid comprises: a first element (10) intended to be positioned in contact with a first bone of a joint; a second element (20), intended to be positioned in contact with a second bone of the joint; the first and second element (10,20) being movable relatively to one another along at least a first direction (X); a displacement sensor (30) predisposed for measuring a relative displacement between the first and second element (10,20); an actuator/motor (50) predisposed for exerting a force that tends to move the first element (10) and second element (20) away from one another; a pressure sensor (40) which measures the force that is exerted between the first and second bone; a processing module (60) arranged to control the actuator/motor (50) so as to calculate the variation of the slope arising from the relationship between distance and force; the processing module (60) receives in input the signal emitted by the displacement sensor (30), the f…
