Keywords
Anterior Cruciate Ligament Reconstruction, Patient-reported outcome, Meniscus, Cartilage
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.
Detailed description
Age 13-65 included. Only include isolated anterior cruciate ligament(ACL) rupture. Excluded revision surgery. Excluded bilateral ACL rupture. Excluded the contralateral ACL tear after surgery. 40 patients at least in each group.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| International Knee Documentation Committee(IKDC) score | Preoperative | 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 | 2 years after surgery | 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 | Preoperative | 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). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Skeletal force line and various angles by X-ray evaluation | Preoperative | X-ray was used to evaluate the skeletal force line and various angles of patients. Use Qvadriceps Angle to evaluate quadriceps force line and patellar ligament force line. The normal Angle is 18-22° for the adult standing position.Above or below this range is considered abnormal. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Biomechanical analysis of human gait | 2 years after surgery | Biomechanical analysis of human gait was performed in all patients under load and no load conditions. Step length, cadence, speed and Angle of patients were evaluated, and then the assessment reports were summarized into similar or abnormal ones with normal people. |
| Rotational torque of knee by Biodex system isokinetic testing | 2 years after surgery | Use Biodex system(BIODEXMEDICALSYSTEMS,INC) to assess the increase or decrease in the amount of rotational torque applied to the patient's limb velocity as it accelerates and decelerates. The equal-velocity quadriceps moment of the operating leg up to 85% of the uninjured side is considered normal. |
