Comparison of kinematic movements between patients with anterior cruciate ligament rupture and post-operative patients and normal people using a mobile dynamic X-ray device.
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.

Difference for 6-Degree of freedom
Evaluate the difference in the result of measuring the six degrees of freedom of the knee joint, including the front and rear potentials of the knee joint, the inner and outer potentials, and the inner rotation/outer rotation. Measure the vertical distance between the femur posterior condyle and posterior tibia. The unit of measurement is millimeter .
