30 patients with the first rupture of the cruciate ligament were divided into two groups as 1:1. Experimental group will be treated with arthroscopic robot-assisted navigation and positioning for cruciate ligament reconstruction. Control group will be treated with conventional reconstruction. This project is used to verify the advantages of surgical robots assisting surgeons in cruciate ligament reconstruction surgery.
In this study, 30 patients with the first rupture of the cruciate ligament were recruited as the research objects, and the ratio of the experimental group and the control group was 1:1. Patients in the experimental group will be treated with arthroscopic robot-assisted navigation and positioning for cruciate ligament reconstruction, and patients in the control group will be treated with conventional reconstruction. All subjects will undergo CT evaluation and clinical function evaluation. This project is used to verify the advantages of surgical robots assisting surgeons in cruciate ligament reconstruction surgery.

3D-CT compares the position of the tibial canal made by the robot-assisted positioning and the traditional positioning method
Evaluate the position of the reconstructed tibia canal through 3D-CT using Taukada's method, t / T × 100% was used to evaluate the anteroposterior radial orientation of the tibial tract. Use l / L × 100% to evaluate the orientation of the inner and outer diameters of the tibial tract.
Time frame: Knee CT examinations were performed on patients one week after surgery
3D-CT compares the position of the femoral canal made by the robot-assisted positioning and the traditional positioning method
Evaluate the position of the reconstructed femoral canal through 3D-CT according to Bernard and Hertel (BH) quadrant method, l / L × 100% and h / H × 100% are used to evaluate the femoral bone canal positioning.
Time frame: Knee CT examinations were performed on patients one week after surgery
