Intervention

Procedure:
• Anatomical single-bundle reconstruction(ASBR method)
406 people were enrolled in the outpatient clinic, after screening for inclusion and exclusion. Of the remaining 243 patients who participated in this RCT, 81 were randomly assigned to the ASBR group to receive anatomic single-bundle reconstruction.We used hamstring as an autograft in the operation, and we chose the anatomical footprint of the anterior cruciate ligament for the positioning of the bone tunnel.Arthroscopic ASB ACL reconstruction was conducted with AMP technique.
• Double-bundle reconstruction (DBR method)
406 people were enrolled in the outpatient clinic, after screening for inclusion and exclusion. Of the remaining 243 patients who participated in this RCT, 81 were randomly assigned to the DBR group to receive double bundle reconstruction.The hamstring autograft is still used for double-bundle reconstruction. The surgical approach is to treat the native ligaments as anteromedial bundles and posterolateral bundles and restore the structure of the two bundles of ligaments in the process of a
• Central axial single-bundle reconstruction(CASBR group)
406 people were enrolled in the outpatient clinic, after screening for inclusion and exclusion. Of the remaining 243 patients who participated in this RCT, 81 were randomly assigned to CASBR group.Arthroscopic ASB ACL reconstruction was conducted with transtibial technique and using Hamstring as autograft.Single-bundle reconstruction is used in CASBR reconstruction surgery. The footprint of the implant on the lateral femoral condyle was chosen to be the location of the AMB bone canal in DB reconstruction surgery while the footprint of the implant on the tibial plateau was chosen to be the location of the bone canal of the PLB in DB reconstruction surgery.

Other:
• rehabilitation training protocol
The rehabilitation program for all patients followed a standardized Process. The first day after surgery, quadriceps sets, straight-leg raises, and prone hangs were initiated. All of the patients were allowed to walk with crutches and braces but with no weightbearing. The range of motion (ROM) progressed from 0 to 90 degrees 3 to 7 days postoperatively and reached 115 degrees within fourth week. Closed kinetic chain exercises and full weightbearing were started in the sixth week. Patients progressed to running without braces at 4 to 6 months.
• Educate patients on return to sports and the importance of quadriceps strength
Patients were interviewed by telephone preoperatively, 6 months postoperatively, and 1 year postoperatively to ask about Tegner scores and to encourage reasonable return to sports from 6 months postoperatively. Inform patients of the possibility of osteoarthritis in patients undergoing ACL reconstruction preoperatively, 6 months postoperatively, and 1 year postoperatively in telephone interviews.Tell the patient that return to sports and quadriceps strength is a must if the knee cartilage damage is to improve.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Magnetic resonance imaging (MRI) to assess graft healing	The difference in signal density between reconstructed ACL and PCL was used to measure graft ligamentation on MRI. Higher signal values represent higher inflammation and lower signal values represent better ligamentation.	At 2 years after surgery
Primary	Quadriceps strength	Side to side quadriceps strength assessed by Biodex arthrometer test	At 2 years after surgery
Primary	Knee laxity (physical exam)	The side to side knee joint laxity of patients after anterior cruciate ligament surgery can be divided into four grades: grade A: -1~2mm(0+), grade B: 3~5mm (1+), grade C: 6~10mm (2+) and D Grade: >10mm(3+) assessed by Lachman test of physical examination.	At 2 years after surgery
Primary	International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form 2000	Patients will be asked to fill out the IKDC2000 score to document the functional status. The minimum is 0 and the maximum value is 100. Higher scores mean a better outcome.	At 2 years after surgery
Primary	Knee laxity (KT-2000 arthrometer)	The knee laxity test of the forward KT-2000 measured knee laxity at pressures of 132Nt, 88Nt, 66Nt, and 44Nt, respectively, while the back-pushing KT-2000 was measured at -132NT, 88Nt, 66Nt, and -44Nt. The foward-pushing KT-2000 asessed side-to-side can be stratified into five levels are (A) < - 1 mm, (B) - 1 to 1 mm, (C) 1-3 mm, (D) 3-5 mm and (E) > 5 mm.; The back-pushing KT-2000 is also divided into side to side differences as (A) < - 2 mm, (B) - 2 to - 0.5 mm, (C) - 0.5 to 0.5 mm, (D) 0.5-1 mm and ( E) > 1 mm.	At 2 years after surgery
Primary	Magnetic resonance imaging (MRI)	Magnetic resonance was used to calculate the graft bending angle (GBA), which is the angle between the intra-femoral graft and the intra-articular graft. GBA is associated with graft widening and graft healing.	At 2 years after surgery
Primary	Magnetic resonance imaging (MRI)	We used magnetic resonance 3D reconstruction to derive the area perpendicular to the bony canal and subdivide it into the proximal, mid and distal bony canal of the tibia and femur. Since CT is harmful to the human body, we used magnetic resonance imaging instead of CT to collect the last follow-up data of bone tract widening during the return visit.	At 2 years after surgery

Secondary	Knee Outcome Survey Activities of Daily Living (KOS-ADLS) Scale	The ADLS is a 14 item scale that queries patients about how their knee symptoms effect their ability to perform general daily activities (6 items) as well as how their knee condition effects their ability to perform specific functional tasks (8 items). Each item is scored 0-5 with 5 indicating "no difficulty" and 0 representing "unable to perform". The highest possible score is 70. The scores of all items are summed, divided by 70, then multiplied by 100 to give an overall ADLS percent rating. Higher percentages reflect higher levels of functional ability. This scale would be appropriate for patients who either do not participate in sports or recreational activities or for those who have not yet progressed to performing these activities	At 2 years after surgery
