The purpose of study is to investigate the difference of the daN force applied during the examination using Telos Device and the degree of fluctuation of anterior cruciate ligament according to the individual differences of the muscles involved in knee stability. The examination was done by the Lachman test using Telos Device and the changes of anterior cruciate ligament were measured by varying the force of 0. 15, 30 daN on each right and left side and the force of 30 daN after the bruce protocol. Computed tomography (CT) was used to measure muscle mass. As a result of measuring the degree of fluctuation of the anterior cruciate ligament according to the change of the force applied to the Telos Device, there was a statistically significant difference in the knee fluctuation when 15 daN and 30 daN were applied on both right and left. Also, it is analyzed that the degree of fluctuation of anterior cruciate ligament varies according to the difference of individual’s muscle mass. Therefore, it is considered that the force applied to the Telos Device should be changed according to the difference of individual’s muscle mass.
