ABSTRACT:
Disclosed is a determination device for the size of a cutting block. The determination device includes the connection device mounted to a tibia to be placed at a top surface thereof along an upper line of a predetermined flexion gap; a body including a slide groove on a central portion of a front surface thereof, a bent part on an upper portion thereof to be placed at a precut anterior cortex of a femur, and a plurality of graduations provided on the body to determine the size of the cutting block; a slider to be slidably engaged with the slide groove of the body and including an indicating line on an upper portion thereof, and a guide to be assembled with the slider and come into surface contact with the top surface of the connection device at a lower portion thereof. The conventional devices are problematic in terms of being incapable of determining a cutting block suitable for the damaged state of a knee joint of a patient because the size of the cutting block is determined by measuring only the height of the femur with no consideration of a flexion gap. The problem encountered in the prior art can be overcome by using the determination device for the size of the cutting block according to the present invention.
