A Clinical Trial of Precise Positioning and Intelligent Operation of Surgical Robots to Reconstruct Cruciate Ligaments

Not Applicable
Conditions
Cruciate Ligament Rupture
Interventions
Device: Arthroscopic surgical robot
Device: Conventional arthroscopic cruciate ligament reconstruction
Registration Number
NCT04980183
Lead Sponsor
Peking University Third Hospital
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.

Primary Outcome Measures
NameTimeMethod
3D-CT compares the position of the tibial canal made by the robot-assisted positioning and the traditional positioning methodKnee 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 methodKnee 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.
