Comparison of Kinematic Movements Between ACL Deficiency With ACL Reconstruction and Healthy People - Investigator Initiated Trial-

Brief Summary

Detailed Description

On a treadmill equipped with a mobile dynamic X-ray device, the subject will take three movements: walking, downhill walking, and squat, and the movement of the knee joint will be tracked. The investigators plan to quantify and compare the motion of the knee joint taken in patients with anterior cruciate ligament rupture, anterior cruciate ligament reconstruction, and normal people according to 6 degrees of freedom. Through this, the investigators plan to compare the functional instability between normal people and the ACL rupture patient group in daily life, and compare this with the ACL reconstruction patient group to see if surgery can reduce knee joint instability in everyday life. To confirm this, with mobile dynamic X-rays taken as the primary variable, the investigators took 1) normal subjects, 2) patients with anterior cruciate ligament rupture, 3) patients with more than 1 year after double bundle ACL reconstruction, and 4) single bundle anterior patients. the investigators plan to compare 6 degrees of freedom between patient groups who have had more than 1 year after cruciate ligament reconstruction and anterolateral ligament reconstruction. As secondary variables, the Lachman test and the Pivot shift test will be compared between the four groups.
