NCT03984474

Brief Summary

Retrospective cohort study. The investigators evaluated the early, middle and long term effects of different surgical methods of anterior cruciate ligament reconstruction on knee function. In the evaluation, the investigators focused on the differences between different age groups, different genders and different basic motor states, the differences between early reconstruction and non-early reconstruction, and the differences in clinical outcomes of different surgical methods.

Outcome Measures

Primary Outcomes (14)

  • International Knee Documentation Committee(IKDC) score

    The entire IKDC form, which includes a demographic form, current health assessment form, subjective knee evaluation form, knee history form, surgical documentation form, and knee examination form, may be used as separate forms. The knee history form and surgical documentation form are provided for convenience. All researchers are required to complete the subjective knee evaluation and knee examination form. Instructions for scoring the subjective knee evaluation form and the knee examination form are provided on the back of the forms. Total score 100, ≥75 being considered excellent.

  • KT-2000 test

    It is a kind of joint measuring instrument used to determine the anteroposterior stability of knee joint. The contrast between the uninjured side and the surgical measurement showed that the difference of ≤3mm was considered excellent.

  • Magnatic Resonance Imaging evaluation

    All patients undergoing anterior cruciate ligament reconstruction underwent MRI imaging evaluation of both knees. Use International Cartilage Repair Society(ICRS) score to evaluate, total score is 12, classified into four grades,grade Ⅰ: normal (12), grade Ⅱ: nearly normal (8-11), grade Ⅲ: abnormal (4-7), grade Ⅳ: severely abnormal (1-3).
