摘要：
Disclosed is a method for evaluating material properties of a knee ligament. According to embodiments of the present invention, the method for evaluating material properties of a knee ligament (S100) comprises: a load application step (S110) of applying a load with a predetermined magnitude to knees in a specific direction while a patient to be measured is lying on his or her side and his or her knees are bent at a predetermined angle； a photographing step (S120) of performing CT scanning on the knees bent at the predetermined angle to obtain photographed data； a knee model generation step (S130) of generating a three-dimensional model for finite element analysis of the knees and setting a material property value of the knee ligament as an average material property value based on the data obtained in the photographing step； a sensitive body part selection step (S140) of selecting a ligament having sensitivity equal to or higher than a predetermined measurement value through sensitivity analysis of the knee ligament； and material property optimization step (S150) of optimizing the material property value of the ligament selected in the sensitive body part selection step based on a pressing force value applied in the load application step and the photographed data obtained in the photographing step. According to the present invention, the method for evaluating material properties of a knee ligament is capable of accurately evaluating the material properties of the ligament of the patient to be measured without conducting a cadaver study by combining a method for specifying by synchronizing a CT device and a TELOS device with a CT device that does not receive a load due to X-Ray Telos measurement.무릎인대 물성 도출방법이 개시된다. 본 발명의 실시예에 따른 무릎인대 물성 도출방법(S100)은, (a) 측정대상환자를 옆으로 눕힌 상태에서, 무릎을 특정 각도로 구부린 후, 무릎에 소정 크기의 하중을 특정 방향으로 가하는 하중인가단계(S110)； (b) 특정 각도로 구부러진 무릎에 대해 CT 촬영을 실시하여 촬영데이터를 획득하는 촬영단계(S120)； (c) 촬영단계로부터 획득한 데이터를 바탕으로 무릎에 대한 유한요소해석을 위한 3차원 모델을 생성시키고, 무릎인대의 물성값은 기공지된 평균
