Cruciate Ligament Rupture
Conditions
Brief summary
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.
Detailed description
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.
Interventions
DEVICEArthroscopic surgical robot
The surgeon performs cruciate ligament bone canal positioning and ligament reconstruction with the assistance of an arthroscopic surgical robot
DEVICEConventional arthroscopic cruciate ligament reconstruction
The surgeon performs conventional arthroscopic cruciate ligament reconstruction surgery without other auxiliary equipment

Inclusion criteria
1. 18-45 years old, with closed epiphyses; 2. For the first time, the knee joint is simply ruptured with a cruciate ligament and requires surgical reconstruction; it can be combined with meniscus injury, and the Outerbridge injury score is ≤ II; 3. There is no history of trauma or fracture of the ipsilateral knee joint; 4. The medial collateral ligament or the lateral collateral ligament is not damaged or only slightly damaged (no more than degree I).
Exclusion criteria
1. BMI is less than 18.5 or greater than 35 kg/m2; 2. Patients with moderate or severe knee degeneration; 3. Those with limited flexion angle (\<120 degrees); 4. Cartilage defect area is greater than 2 cm2 or Outerbridge damage score\> Grade II.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 3D-CT compares the position of the tibial canal made by the robot-assisted positioning and the traditional positioning method | Knee CT examinations were performed on patients one week after surgery | 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. |
| 3D-CT compares the position of the femoral canal made by the robot-assisted positioning and the traditional positioning method | Knee CT examinations were performed on patients one week after surgery | 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. |
