Clinical Trial Summary

It is difficult to establish the standard of return to sports post anterior cruciate ligament (ACL) reconstruction. The amplitude of low frequency fluctuation (ALFF) and functional connectivity (FC) of resting state functional magnetic resonance imaging (fMRI) can explore the differences in neural function of different populations, but have not been applied in the study of ACL postoperative return to sports.This project intends to use ALFF algorithm to calculate the changes of BLOD signals of coppers and non- coppers after ACL surgery in the subfrequency band and the functional network in the subfrequency band, explore the relationship between the default network (DMN) and the sensorimotor network (SMN), and use three-dimensional gait analysis to carry out accurate functional test..This project will explore the central strategy of ACL postoperative functional recovery from a new perspective, to provide a more reasonable high-level evaluation index for the timing of return to sports, and to reduce the incidence of postoperative re-tearing.

Outcome

Type Measure Description Time frame Safety issue
Primary ALFF ALFF algorithm to calculate BLOD signals in the subfrequency band of resting state functional magnetic resonance imaging (fMRI) 2 years post-operation
Primary FC functional connection between brain region of interest in the subfrequency band of resting state magnetic resonance imaging (fMRI) 2 years post-operation
Secondary Lysholm Lysholm scale, which is used to measure the functional status of a patient's knee joint has a minimum value of 0 and a maximum value of 100, with the higher the score, the better the function 2 years post-operation
Secondary Tegner Tegner scale,which is used to measure the functional status of patients has a minimum value of 0 and a maximum value of 10, with the higher the score, the better of the function. 2 years post-operation
Secondary COP(center of pressure ) symmetry of center of pressure transfer path by using Plantar pressure testing system when patients are walking and running. limb symmetry index =injury limb score/good limb score *100 2 years post-operation
Secondary CR Hamstring Co-contraction ratio(CR) in the Single foot support phase by using the Surface electromyography when patients are walking and running. 2 years post-operation
Secondary single leg jump test Patient stands onhis or her leg , toe on starting line, try to jump forward and land on ipsilateral limb, measure the distance between starting line and patient's feet. limb symmetry index =injury limb score/good limb score *100 2 years post-operation
Secondary 6M timing single leg jump test The patient stood on his or her leg, with the toes on the starting line. After the tester gave the command of "each in position, prepare, run", the chronograph was accurate to 0.01 seconds to start the time. The patient's healthy limbs jump as soon as possible and stop the timing when reaching the 6m terminal.limb symmetry index =injury limb score/good limb score *100 2 years post-operation
